Multiarchive RAR bash script (SOLVED)

Dear Fellow Archies!
I use the command
rar a -w<working_folder> -m5 -v<max_volume_size> <archive_name> <target_file_or_folder>
whenever I need to make a multiarchive rar file, because I have not yet found a GUI archive manager that does this.
So, I've decided to write a simple bash script to make things easier.
Here's the script:
#!/bin/bash
echo Please, enter the full path to the target file or folder [without the target itself]!
read PATH
echo Please, enter the target filename [with extension] or folder name!
read TARGET
echo Please, enter the desired archive name [without extension]!
read DESTINATION
echo Please, enter the desired volume size in KB!
read SIZE
rar a -w$PATH -m5 -v$SIZE $DESTINATION $TARGET
Executing the last line of the code in terminal works without any hassle. When I run this entire script however, it doesn't.
What needs to be changed for the script to work?
RAR man page is HERE - CLICK, in case someone needs to take a look at something.
Thank you and thank you,

Done! Working!
Geniuz: Logout-login did it. How simple.
Juster: I added "echo $PATH" to the script and ran it with "bash -x". And the output was the same as after the logout-login. Here it is, in case you are curious.
/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/bin/core_perl:/opt/qt/bin
Thank you all for your help guys :bow:.
OFFTOPIC:
All who intend to use Xfce launchers to run bash scripts: There are two options in the settings for each launcher: "Command" and "Working Directory". And when I had "Working Directory" filled with "/home/username/", the script didn't work. It worked perfectly after I blanked out the "Working Directory" option. Just so you know, in case someone doesn't .
This has never happened to be before, but still, I guess it is better to do it with blank "Working Directory" and entering the entire path into the script in the "Command" field. It might be that Xfce launchers always stick to the "Working Directory", even though a script might tell them otherwise.

Unexpected token `(' in my bash script [Solved]

I've been working on a bash script, and I'm trying to get it to move all directories that are not named certain names to another directory.
EDIT: Fixed the thing papajoke pointed out
#!/bin/bash
mv ~/Downloads/!(folders|pics|docs|code|archives|vids|sounds)/ ~/Downloads/folders/
The command from the script does what I want it to do when I run it from a terminal.
It also works if I run the script as follows:
source script.sh
It doesn't work like this:
bash script.sh
I'm trying to get it to run when I login, and using the running the command with "source" in my MATE Startup Applications doesn't work.
I'm new to bash scripting, any help would be much appreciated. Thanks

[solved] Running a command in background (bash script)

Salut,
as netcfg2 does not work with my wireless connection, I have to set up the connection manually. For not having to type in the commands every time, I created a bash script.
#!/bin/bash
iwconfig wlan0 mode managed essid mynetwork channel 6
ifconfig wlan0 up
wpa_supplicant -D wext -i wlan0 -c /etc/wpa_supplicant.conf -dddd &
dhcpd wlan0
This works fine till the wpa_supplicant line. wpa_supplicant is not started in the background (as I thought, the ampersand at the end of the line would.
So how can I get wpa_supplicant run in the background?
Thanks in advance,
Stefan

The script does not return to the user-prompt. Is an ampersand at the end of the line the correct solution, or are you unsure yourself?
bender02 wrote:On thing is that even if it starts, it does take it a couple of seconds to connect, so it's probably not very good to run dhcpcd right after wpa_supplicant. Another thing is that you probably have a typo up there, shouldn't it be 'dhcpcd' instead of 'dhcpd'?
Well, as the wpa_supplication command is not really run in the background the script did never execute the dhcpcd command. After having solved the above, correcting the spell-mistake will be a smaller problem. Even calling the dhcpcd command myself would be no unworkable way, the open root-shell (as I have to use another as the one calling the script is blocked) is a far greater problem...

[SOLVED] problem with spaces and ls command in bash script

I am going mad with a bash script I am trying to finish. The ls command is driving me mad with spaces in path names. This is the portion of my script that is giving me trouble:
HOMEDIR="/home/panos/Web Site"
for file in $(find "$HOMEDIR" -type f)
do
if [ "$(dateDiff -d $(ls -lh "$file" | awk '{ print $6 }') "$(date +%F)")" -gt 30 ];
then echo -e "File $file is $(dateDiff -d $(ls -lh "$file" | awk '{ print $6 }') "$(date +%F)") old\r" >> /home/panos/scripts/temp;
fi
done
The dateDiff() function is defined earlier and the script works fine when I change the HOMEDIR variable to a path where there are no spaces in directory and file names. I have isolated the problem to the ls command, so a simpler code sample that also doesn't work correctly with path names with spaces is this:
#!/bin/bash
HOMEDIR="/home/panos/test dir"
for file in $(find "$HOMEDIR" -type f)
do
ls -lh "$file"
done
TIA

oops, brain fart. *flushes with embarrassment*
-- Edit --
BTW, for this kind of thing, I usually do something like:
find "$HOMEDIR" -type f | while read file ; do something with "$file" ; done
Or put those in an array:
IFS=$'\n' ; files=($(find "$HOMEDIR" -type f)) ; unset IFS
for file in "${files[@]}" ; do something with "$file" ; done
The later method is useful when elements of "${files[@]}" will be used multiple times across the script.

[solved] Segmentation fault with bash script

I have a bash script that checks if it has to do something, if not it sleeps 15 secs and checks again. It works great except that after ~6hrs of just checking and sleeping it seg faults. I upped the stack limit with ulimit -s and it goes ~12hrs before it seg faults. I have a similar script that I have been using for ages that works for 24hrs no problem and I can't pinpoint where the problem is.
The check it does is to see if a file exists, if it's empty and if not, read the first line of a file and do some date comparisons. It doesn't matter if the file is empty or not the seg fault always happens.
Here's the seg fault causing script - it starts at the bottom

[solved]Need help with a bash script for MOC conky artwork.

I need some help with a bash script for displaying artwork from MOC.
Music folders have a file called 'front.jpg' in them, so I need to pull the current directory from MOCP and then display the 'front.jpg' file in conky.
mocp -Q %file
gives me the current file playing, but I need the directory (perhaps some way to use only everything after the last '/'?)
A point in the right direction would be appreciated.
thanks, d

You should also quote the variables and output in double quotes to make the code robust, e.g.
filename="$(mocp -Q %file)"
dirname="${filename%/*}"
cp "$dirname"/front.jpg ~/backup/art.jpg
Without the quotes, whitespace will break the code. Even if you don't expect whitespace in any of the paths, it's still good coding practice to include the quotes imo.
thanks for the tip.
here it is, anyhow:
#!/bin/bash
filename=$(mocp -Q %file)
dirname=${filename%/*}
cp ${dirname}/front.jpg ~/backup/art.jpg
then in conky:
$alignr${execi 30 ~/bin/artc}${image ~/backup/art.jpg -s 100x100 -p -3,60}
thanks for the help.

[SOLVED]bash script

I had created a bash script which ensures that each of the applications has one instance. The problem is no applications are executed during startup. Here is my script:
if [ -z "ps aux | grep wmCalClock | head -n -1" ]
then
wmCalClock -b 100 -arial -tc cyan -bc black -e xterm &
fi
if [ -z "ps aux | grep wmfire | head -n -1" ]
then
wmfire -L1 -B1 -s0 -C2 -P fireload_temp &
fi
if [ -z "ps aux | grep wmcpuload | head -n -1" ]
then
wmcpuload -lc red -a 95 &
fi
if [ -z "ps aux | grep wmmemload | head -n -1" ]
then
wmmemload -lc red -am 95 &
fi
Last edited by heyya (2009-12-25 04:19:33)

Well, obviously not, as the string "ps aux | grep wmCalClock | head -n -1" is
never empty What you probably wanted to write is
"$(ps aux | grep wmCalClock | head -n -1)"
This will put the output of the script into the string, rather than taking the
command string itselft.

[SOLVED] How to get BASH scripts to recognize mounted partition paths?

I don't understand how to get the bash script in the root partition to find the boot partition--both mounted at /mnt.
I'm following the instructions on configuring "dm-crypt with LUKS" tutorial. The mkinitcpio command to generate the "initial ram disk environment" is producing an error while the system is booted from the install disk and the volumes it looks for are mounted at /mnt.
#mkinitcpio -p linux
==> Building image from preset: /etc/mkinitcpio.d/linux/preset: 'default'
-> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux.img
==> ERROR: specified kernel image does not exist: `/boot/vmlinuz-linux'
==> Building image from preset: /etc/mkinitcpio.d/linux/preset: 'fallback'
-> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux-fallback.img -S autodetect
==> ERROR: specified kernel image does not exist: `/boot/vmlinuz-linux`
The script located in /mnt/root/etc can't find the "temporary kernel" located at /mnt/boot.

And read them carefully, there should be no /mnt/root/etc/.
There should be a /mnt/etc/ and a /mnt/boot and /mnt/root/ which is the root user's home directory, not the root filesystem (and of course /mnt/usr ...) - or if you decide to nest the whole thing deeper you could have /mnt/somename/etc and /mnt/somename/boot ...

[SOLVED] XMMS2 media hotkeys, bash scripts

Hi!
For the really beginners of the XMMS2 users as me, should be a nice something like a guide/tutorial.
Here is the bash scripts that might enchant functionality and be more useful for use of the media keys.
For randomizing before any other action you can use even something like:
xmms2 playlist shuffle ; xmms2 jump 1; xmms2 play
# Just for dummies
The Preview hotkey loop.
From the begin of the playlist to the end of it when current is the first one being played:
#!/bin/bash
#Play the previews or first if end of the playlist
if [ "XX"$(xmms2 prev | awk '{print $1}') == "XXServer" ] ; then
if [ "XX"$(xmms2 jump $(xmms2 list | grep -i '/' |wc -l) | awk '{print $1}') == "XXServer" ] ; then
xmms2 playlist list;
echo The playlist is empty, please choose one from of the above ;
echo or add a new songs to the playlist with a '"xmms2 add"';
fi; fi;
#It takes time to count to the last song in the playlist, longer it is more time it takes :(. I haven't found a better way yet.
The Next hotkey loop.
When the end of the playlist is reached then goto jumping to the first one song in the playlist:
#!/bin/bash
#Play the first song if in the end of the playlist
if [ "XX"$(xmms2 next | awk '{print $1}') == "XXServer" ] ; then
if [ "XX"$(xmms2 jump 1 | awk '{print $1}') == "XXServer" ] ; then
xmms2 playlist list;
echo The playlist is empty, please choose one from of the above ;
echo or add a new songs to the playlist with a '"xmms2 add"';
fi; fi;
For the Play/Pause key:
#!/bin/bash
#For the single Play/Pause key
GetStatus=$(xmms2 current | awk -F":" '{print $1}')
#Any command line parameters to the script for randomizing of the playslist.
if [ "S" != "S"$1 ] ; then
xmms2 playlist shuffle
fi;
if [ "$GetStatus" == "Playing" ]; then xmms2 pause;fi
if [ "$GetStatus" == "Paused" ]; then xmms2 play;fi
if [ "$GetStatus" == "Stopped" ]; then
xmms2 play
GetStatus=$(xmms2 current | awk -F":" '{print $1}')
if [ "$GetStatus" == "Stopped" ]; then
xmms2 playlist list;
echo The playlist is empty, please choose one from of the above ;
echo or add a new songs to the playlist with a '"xmms2 add"';
fi
fi
or you can use even xmms2 toggle command line for the play/pause hotkey.
Turn On/Off repeat/loop of the playlist:
#!/bin/bash
GetStatus=$(xmms2 server config playlist.repeat_all )
case $GetStatus in
"playlist.repeat_all = 1") xmms2 server config playlist.repeat_all 0 ; sudo beep; echo is OFF ;;
"playlist.repeat_all = 0") xmms2 server config playlist.repeat_all 1 ; sudo beep ; sudo beep ; echo is ON;;
esac
You can install beep but the beep has a problem, you can run it only as a root but a more danger way is to by pass this by adding the beep into /etc/sudoers , e.g. yourusername ALL=NOPASSWD: /usr/sbin/beep. Be careful! It may expose your system for unwanted access to and do a harm. The best way is to find a better way for notification of changes.
If someone has another script solutions for the multimedia hotkeys or media fun for XMMS2 then please share with us!
Automation is power of the shell
Notice
The hotkey names of my Digital Media Keyboard 3000, but I think that it becomes more as a standard, it is just to get a faster access to the names.
XF86AudioPlay, XF86AudioNext, XF86AudioPrev,XF86AudioStop
XF86AudioMute (amixer -c 0 set Master toggle), *, (pactl set-sink-mute 0 toggle)
XF86AudioRaiseVolume (amixer -c 0 set Master 3+), xmms2 server volume +3, (pactl set-sink-volume 0 +3%)
XF86AudioLowerVolume (amixer -c 0 set Master 3-). xmms2 server volume -3, (pactl set-sink-volume 0 -- -3%)
amixer = ALSA
pactl = PulseAudio (0 is index of the sinks, you can see which you can use with pacmd list-sinks, marked with * is default)
The other way to increase and decrease volumes is here.
Change between ALSA and PulseAudio sound servers for XMMS2
nyxmms2 server config output.plugin pulse
nyxmms2 server config output.plugin alsa
Otherwise you can use xev to retrieve the names of the supported keys by X server, as I know X server has a limitations to the 255 key numbers/keycodes. One more but less useful for GUI is showkey, just to know that it is also and always exists, with a great manual about the kbd keys.
* To mute/unmute XMMS2 you can use xmms2 server volume 0 / xmms2 server volume 100 or for more advanced e.g. xmms2 server volume -c left 100/xmms2 server volume -c right 100 and combine with any keys you wish the way is best for you. I haven't found any way to make anything to remember status after mute/unmute of xmms2. Alias for the mute only is xmms2 mute. If you will find it before me please help .
Here is one more guide for the BlackBox menu. I could not get xmms2 mlib loadall to work in Arch.
In Arch you must use xmms2 playlist sort instead of xmms2 sort because it doesn't work otherwise.
xmms2 playlist sort album
xmms2 playlist sort title
xmms2 playlist sort artis

/mnt/dvd
& the root list of the optical media is displayed in the active panel of Worker.
I just haven't been able to get Worker to use "mount /mnt/dvd" yet, there will be a way, I wonder how long it will take me to find it? lol

[SOLVED] Bash scripts to mount & unmount optical drive in Worker?

I'm running XFCE on Arch with the HAL daemon being called in /etc/rc.conf.
I can access media on my optical drive (DVD's or CD's) through the desktop icon that appears after HAL has recognised the drive, VLC automatically does its thing as does NeroLinux.
The reason I'm posting is that I found a great DOpus clone yesterday called Worker - http://www.boomerangsworld.de/cms/worker/index?lang=en, which I am in the process of configuring.
A problem I have is being able to access the optical drive via Worker.
The way it is on my system, with HAL handling it, the first line (see below) appears after HAL mounts the media, which basically makes the two lines below it useless:
/media/<title of disk>
/media/cd
/media/dvd
I have tried configuring Worker to use /media/dvd (or cd), to access the optical media, these don't work for the reason stated above, & /dev/sd0 doesn't work either.
So, do I have to turn off HAL, uncomment the lines in fstab & use mount?
A little bash script, that would do the job for me would be great, as Worker will accept a script or a command string.
I am a bash baby, so if someone can see a solution please post it?
All input welcome.
Thanks.

I found the clues for this in the sudoers manual:
handy ALL = NOPASSWD: /sbin/umount /CDROM,\
/sbin/mount -o nosuid\,nodev /dev/cd0a /CDROM
Which works in so far as now mounting no longer needs the password.
Which leaves me with the problem of trying to understand how to get Worker to mount the optical drive on command.
If I enter the bash command in the Terminal as follows:
mount /mnt/dvd
the media is mounted, after which I can push the button in Worker, which I have configured with:
/mnt/dvd
& the root list of the optical media is displayed in the active panel of Worker.

[Solved] Selecting folder span in bash script

Hey all,
Recently, I decided to get an audio-book from Audible and discovered the mp3 player they advertise about is only for ipods. This meant that the only legit way to transfer it to my mp3 player (an .aa file/DRM protected) was to use iTunes burn it to multiple cds. Doingthis had the book span 14 disks and now I'm trying to put it back together. I used a great program called 'ripit' to rip the files back to Linux and now I'm faced with the task of concatenating the files back together again. Ripit ripped the disks to 14 separate folders:
Unknown Artist - Unknown Album
Unknown Artist - Unknown Album 1
Unknown Artist - Unknown Album 2
Unknown Artist - Unknown Album 13
To get these to appear in correct order I first rename the first album:
mv Unknown\ Artist\ -\ Unknown\ Album/ Unknown\ Artist\ -\ Unknown\ Album\ 0
replaced white spaces with hyphens (necessary for the next step):
find -name "* *" -type d | rename 's/ /-/g'
Zeropad the numbers to show in the right order (using this persons excellent script - http://www.walkingrandomly.com/?p=2850):
for i in *; do mv "$i" $(zeropad "$i"); done
#!/bin/bash
# zeropad
# Filter that will take input with basic numbering and zero pad it (i.e. file002)
# e.g. mv file1.png `$(zeropad) $i`
# http://www.walkingrandomly.com/?p=2850
num=`expr match "$1" '[^0-9]*$[0-9]\+$.*'`
paddednum=`printf "%03d" $num`
echo ${1/$num/$paddednum}
So now my directories look like this:
Unknown-Artist---Unknown-Album-000
Unknown-Artist---Unknown-Album-001
Unknown-Artist---Unknown-Album-013
Now I'm trying to create a bash script that will put this mp3s back together again. mp3cat is the right utility to do this so I need to create a bash script that I can tell what folders to use to put them together. Originally the book from Audible came in three parts:
SK...part1.aa
SK...part2.aa
SK...part3.aa
part 1 covers directories 000 to 004, part 2 005 to 008, part 3 009 to 013. The script though I'd like to be generic (to be able to accept input if I decided to ever do this again). Here it is thus as I have it so far figured out:
echo "Join multiple mp3s from which folders?"
echo -n "First folder number [0xx]: "
read first_folder
echo -n " to folder number [0xx]: "
read final_folder
echo -n " Name of file [name].mp3: "
read filename
for f in Unknown-Artist---Unknown-Album-[$first_folder-$final_folder]; do
cat "$f"/*.mp3 | mp3cat - - > "$filename".mp3
done
I'd like to be able to input which directory to begin with and then input which directory to end with. My use of [$first_folder-$final_folder] here shows my limited use of bash and I know that this this is only going to work for a single digit. Any ideas what I can do here?

If there are spaces in the filenames then using globbing won't change anything. When stored in an array the new elements are split at spaces. This has the same problem as using ls. edit: ok so, "newer" versions of bash won't split the elements at spaces but the spaces still screw up when the array is expanded to command arguments.
As usual all problems of existence are just a primitive form of bending. I mean, sorting! Crap. No need to remove the spaces and rename everything. sort and awk like spaces.
# Must... have... number!
mv "Unknown Artist - Unknown Album" "Unknown Artist - Unknown Album 0" \
2>/dev/null
# Sort & awk read as many number chars as possible, then give up.
# ./Unknown Artist - Unknown Album 1/Track 1.mp3
# (Fields) 6_/*^^^^^^ *^^^^\_7
find . -name '*.mp3' | sort -n -k6 -k7 | \
# $6+0 coerces $6 into a number.
awk -v beg="$1" -v end="$2" '$6+0 >= beg && $6+0 <= end' |
# Use NULL chars instead of newlines to make xargs happy.
tr '\n' '\0' | xargs -0 cat
# Without NULL chars and -0, xargs splits on lines AND spaces. Bad.
Instead of changing the data (paths) to make it sort lexicographically, I simply sorted the data explicitly. Two args: beginning number and ending number. It's probably too late, since you renamed everything but maybe you can use the tr | xargs trick. Avoid using bash arrays or get rid of the spaces in the filenames.

Using Bash script to edit config file

This is a really simple question, but given that I'm just learning Bash scripting and having this solved now would be really illustrative for me, I would really thank some help here.
I'm using uzbl, and running Tor+Polipo. So, as you will see below in the tail of the config file, there is a line to redirect the requests of uzbl through Polipo.
# === Post-load misc commands ================================================
sync_spawn_exec @scripts_dir/load_cookies.sh
sync_spawn_exec @scripts_dir/load_cookies.sh @data_home/uzbl/session-cookies.txt
# Set the "home" page.
#set uri = https://duckduckgo.com
# Local polipo proxy
set proxy_url = http://127.0.0.1:8123
# vim: set fdm=syntax:
What I want to accomplish is to comment in/out that line with a key shortcut on Awesome. I've thought of doing 2 scripts to do so and using 2 differente key shortcuts, but I want to "toggle" the proxy redirection with only 1 shortcut. To do so, I suppose that the script should go something like:
if
tool 'set proxy_url = http://127.0.0.1:8123' config_file
then
tool '#set proxy_url = http://127.0.0.1:8123' config_file
else
if
tool '#set proxy_url = http://127.0.0.1:8123' config_file
then
tool 'set proxy_url = http://127.0.0.1:8123' config_file
fi
fi
I know little about sed, but I think is the tool for this job. The most intriging part to me is to ask sed to print the regular expression when it finds it in the config file, and use that as an input in the conditional statement.
Well, this is a mess I have done here. Hope there is a simple answer to this.
Thanks in advance.-

You can do this with a single sed command:
sed -i 's/^#set proxy_url/set proxy_url/;
t end;
s/^set proxy_url/#set proxy_url/;
: end' config_file
This edits the file in-place (-i) and first tries to replace the commented with the uncommented line. If that suceeds, sed jumps to the "end" label. If not, it tries to replace the uncommented with the commented line. Thus you don't have to include any logic about the current state: if the first substitution succeeds, the line was obviously commented, if not, it was uncommented, and the second substitution should succeed.
Note that my knowledge of sed is very limited. There might be a simpler way to do this.
EDIT: For the sake of example, here's how to do the same in bash using regular expressions. Note how this script needs to use a temporary file to simulate in-place editing, how it needs to process the file line by line manually, etc. All things that sed does out of the box...
#!/bin/bash
tmp=test.conf.tmp
echo -n "" > "$tmp"
while read line; do
if [[ "$line" =~ ^#set\ proxy ]]; then
echo "${line/\#/}" >> "$tmp"
elif [[ "$line" =~ ^set\ proxy ]]; then
echo "#$line" >> "$tmp"
else
echo "$line" >> "$tmp"
fi
done < test.conf
mv test.conf.tmp test.conf
To answer your original question, the line
if [[ "$line" =~ ^#set\ proxy ]]; then
reads: if the line begins with a "#", followed by "set proxy", then...

Bash script to dumpstream many files simultaneously with mplayer

hi guys
i have a problem which i´m sure can be solved with the power of bash scripting
unfortunately i´m no bash scripting guru and all my experiments failed so far
the problem:
i have a file in which are links(streaminglinks)
mplayer offers the funtion to dump such a stream with simply issuing
mplayer -dumpstream mms://path/to/video -dumpfile video1
for example.
now i want mplayer to download this streams specified in the links-file automatically.
basically all it required is a bash script which goes through the link file and generates a command like mplay -dumpstream <link> -dumpfile video<n>
(where n is the nth link) and execute it.maybe there a even simpler solutions
well since i´m not that experienced with bashscripting i can´t solve that problem at my self....
i´m grateful for any help

hey guys
thx for the two scripts.
my approach was nearly the same as your´s kraluz with the difference that it doesn´t work
but they both have a little blemish
they download the files sequentially not simultaneously
how could that be realised
thx in advance

Bash Scripting with Conky -- How to implement?

Hey Folks, my first post here and I'm looking for a bit of help. I've created a bash script to work with conky in which its purpose is to change the color of the battery bar depending on current voltage.
Here's the bash script:
#!/bin/bash
# Change Conky battery color depending on charge
chrg=`cat /proc/acpi/battery/BAT1/state | grep "remaining capacity" |
awk '{print $3 }'`
echo $chrg
if [ $chrg -lt "3499" ]; then
${color red}${battery_percent BAT1}% ${battery_bar 4 BAT1}
elif [ "$chrg" -lt "5100"]; then
${color orange}${battery_percent BAT1}% ${battery_bar 4 BAT1}
else ${color green}${battery_percent BAT1}% ${battery_bar 4 BAT1}
fi
Essentially what it is supposed to do is grab and store the "remaining capacity" and if its lower than a certain point it changes color. What I'm having trouble with is actually implementing the colors into conky. Right now all it is doing is printing the charge as you can see. Any help would be appreciated. Thanks!

I had this issue, took me three days to solve. Using if_match, put all your if_matches in a line, with each option having its color of choice, then put the bar, or % at the end. You will need to make sure it is in sequential order so the color will not overlap the color you want for the state in the if_match. I know this is an old thread, I will edit my post when I get on my netbook with the code.
I found this thread on a google search for bash and conky usages.
[edit] here was my solution for the if_match using the battery.
${if_match ${battery_percent BAT1} <= 49}${color0}${endif}${if_match ${battery_percent BAT1} <= 20}${color9}${endif}${if_match ${battery_percent BAT1} >= 50}${color4}${endif}${battery BAT1} ${alignr}${battery_bar 6,160 BAT1}
I have my colors set yellow for 49% and below, red 20% and lower, and last green for 50% and higher. Essentially this will pick yellow for under 49% and the if_match for red under 20%, the red will override the yellow, this is why order is important.
Remember this is all in one line, now there are cleaner ways of setting this up using lua. That is something I am still working on.
