[SOLVED] Parsing output of pacman -Qm to an bash array

Hey guys,
I'm currently writing a small bash script to check if there are any updates for my packages installed from the AUR. For this I need to get an array from the output of
pacman -Qm
. I've tried this
packages=(`pacman -Qm`)
, but this isn't that what I've intended for.
I want to have an array like this
packages=("packagename version", "packagename version" ...)
Does anybody know the way, how to solve this problem?
Best regards,
the_metalgamer

Just to clarify this:
With the solution in post #2 the IFS variable will contain just an "n". So any package name containing an "n" will be cut into pieces.
$ echo ${packages[1]}
e emyli es3 1.2-1
The correct splitting is not caused by the IFS variable but by the read command which ALWAYS stops reading at a newline no matter what the IFS is set to. So there is no need to set the IFS variable to anything different and just use
packages=(); while read -r; do packages+=("$REPLY"); done < <(pacman -Qm)

Error parsing output

Hi There,
New to the Java World and Im getting the following error when submitting this java program for compilation and output. Output is Via a html page
// just import the BufferedReader and inputstream reader
import java.io.BufferedReader;
import java.io.InputStreamReader;
class addtwonumbers
    public static void main(String[] args)
    // system.in reader (e.g. the input from the console)
    InputStreamReader ISR = new InputStreamReader(System.in);
    // buffer the console reader
    BufferedReader BR = new BufferedReader(ISR);
    // the default values for the two numbers
    int val1 = 0;
    int val2 = 0;
    try
        // output the question.
        System.out.print("Enter two Numbers:\n");
        // read in the console intput one line (BR.readLine) and then convert to a integer
        val1 = Integer.parseInt(BR.readLine());
        val2 = Integer.parseInt(BR.readLine());
    catch (Exception ex)
        //if the input was a string.
        System.out.println(ex.toString());
    // output the answer of adding both of the values together and * by 3
    System.out.println("The result is " + (val1 + val2) * 3 );
The error message is "Error parsing output, please try again"
Thanks In advance.

Hi,
What you mean by HTML page(in a table)?
Code what you have written above is a pure application that need to be run in the way i have mentioned above.
If you are interested to create a HTML page where you can enter two numbers and print their out put. You need to change the code altogether.

I never heard of libalpm, but I'll look into for my own information.
If I added the functionality to pacman itself (assuming i knew how), I would have to change the source and recompile every time there was an update. My program should work with new versions unless there is a major change to the output of pacman -Qi(e).
My "program" produces the following output format:
52dec liba52 is a free library for decoding ATSC A/52 streams. 207.860
aalib AAlib is a portable ASCII art GFX library 824.000
abiword A fully-featured word processor 12,833.000
abiword-plugins Various plugins for Abiword 4,199.000
It can be read with a regular text editor or a spreadsheet where it can be sorted by size if you want to see whats taking up hardrive space without scrolling through the detailed output of pacman -Qi.
Obviously, the program has extremely limited usefullness unless you just want to to see installed programs, it description and size in a more compact format either out of curiousity or your planning on reinstalling but want to see the descrition as well as the program name.
I appologize if this functionality is already available in libalpm or elsewhere, but I figured I'd put it up in case anyone wanted it.
Thanks for the additional information.

[Solved] Parsing findmnt output?... Is it reliable/portable in bash.

Solution/better suggestion in second post...
There seems to be little about using anything other than the output of mount or fstab when dealing with filesystems in scripting. Most of what I've read on it uses awk or cut for parsing "mount" but what about findmnt when needing some of the same info. particularly "findmnt -rn" which prints the same raw information as mount but space separated and without the words like "type" and "on". I'm not entrirely concerned with posix compliance as most of it amount to makings it compatible with much much older systems. Personally I think bash has been around long enough to be portable in and of itself in most circumstances but that's just my opinion. Is "findmnt" as portable as "mount" for scripting? that is really my question.
An example would be say I wanted only the "target" and "source" information stored with process substitution in bash.
with mount I could use
#mount | cut -d ' ' -f 1,3
to get that info for all mounted filesystems
OR
#mount | grep sdb1 | cut -d ' ' -f 3
to get where a particular partition (/dev/sdb1) is mounted.
with findmnt it would be just as simple but take the words "on" and "type" out of the parsing.
#findmnt -rn | cut -d ' ' -f 1,2
or for the second example using mount...
#findmnt -rn | grep sdb1 | cut -d ' ' -f 1
if neither of these are the best for getting simple information then I can accept other suggestions as well.
Think of the pipe to grep section having a variable with the needed string instead of "sdb1" for instance...
maybe this is just a minor formatting discrepancy. If so feel free to point it out... I'm kinda on my journey of do's and don't's in shell scripting with only google and the man pages as my resources for learning.

This is an entire misuse of findmnt. If you're going to talk about "portable" or "POSIX", then you can't even use mount.
If you want specific columns from findmnt, then ask for them. Specifically, the -o option is your friend, i.e.
$ findmnt -runo source,target /dev/sdb1
/dev/sdb1 /home
If you're looking for some absurd level of portability where you might encounter systems that don't have findmnt, then you'll need to build a parser for /etc/mtab, and even that isn't portable.
That's clear enough to me. And no I wasn't too interested in POSIX compliance. It seems like overkill in most circumstances. As for the findmnt options.. I should have read the man page a little more... totally skimmed over it... I'll mark this as solved...

[SOLVED]Need to parse output data

I have a program that outputs data to the console in this format:
[1] banana
[2] orange
[7] apple
[17] grape
[42] strawberry
I would like to strip this output and only get the values for [2] and [17]. So my output would be:
orange
grape
My first idea was to pipe the output to grep and then possibly use sed to strip the preceding numbers and brackets. What is the recommended way to do this and why? Is there a better suited utility that I'm not aware of?

Very true.

The idea to use sed was correct, nadman10. You should have googled
remove "square brackets" sed
and you would have found out the answer yourself: http://www.unix.com/showthread.php?t=159143
The slightly tricky part with the square brackets is that they have special meaning, so you have to escape them i.e. precede them with '\'.

[SOLVED] HDMI output not working

I just bought myself a home theater system but can't get my laptop to connect to the reciever.
My laptop is an Asus UX31E with integrated HD 3000 graphics. When I connect a HDMI cable to the reciever (Pioneer VSX-527) it doesn't even detect my laptop. If I go into the Cinnamon/GNOME display settings, it doesn't even show that I'm connected to an external display.
In pavucontrol I'm able to select the HDMI as an output, but it doesn't play any sounds on the reciever (which plays just fine from radio, so at least the speakers are connected correctly).
What to do?
Edit:
And here's the output from xrandr:
HDMI1 disconnected (normal left inverted right x axis y axis)
Solved:
Derp, faulty cable.

Hi:
The only suggestion I can offer would be to try the graphics driver from AMD if you have not already done so.
Your notebook is not supported by HP for W7, and especially not supported for 32 bit operating systems.
http://support.amd.com/en-us/download/mobile?os=Windows%207%20-%2032
As a last resort, try manually installing the W7 x64 graphics driver from your notebook's support and driver page (sp66999).
I explored the driver folder, and there are 32 bit drivers included in that file.

[SOLVED] X fails after pacman -Syu

After a year or so without upgrading (not recommended) I did a pacman -Syu; it took like ages 'cause I was on kernel 2.26, and now my arch is a complete mess: user modules don't load at boot, dhcpcd is not working so I don't have internet access and the X server is erratic too.

So you updated everything except gnome-stuff? Update the gnome-stuff.
But I'm all for gnome 2 , and X should work despite of the gnome version or the desktop environment. Shouldn't it?
No, not if you're using gdm or autoboot into gnome or something similar.

This sounds like one of gnome-sessions dependencies have been updated and isn't compatible with gnome-session anymore.

[SOLVED] Parsing simple config files in pure bash

Hi everyone,
I'd like to implement a bash function to parse a simple config file for a script I've wrote. The conifg file contains different sections for different scenarios. Here's an example how it should look like:
# configuration file
# global settings
global {
DATE_PREFIX="-I"
SSHFS_OPTS="-C"
EXT_FULL="full"
EXT_DIFF="diff"
EXT_CATALOGUE="catalogue"
DAR_OPTS="-v -m 256 -y -s 600M -D"
DAR_NOCOMPR="-Z '*.gz' -Z '*.bz2' -Z '*.zip' -Z '*.png'"
# system settings
system {
DAR_OPTS="-v -m 256 -y -s 200M -D"
It contains some settings which are global for the whole script and special settings groups which can be used to overwrite global settings.
The function to parse this config file looks as follows:
#!/bin/sh
CONFIG="/home/chi/.daruprc"
function readconf() {
match=0
while read line; do
# skip comments
[[ ${line:0:1} == "#" ]] && continue
# still no match? lets check again
if [ $match == 0 ]; then
# do we have an open tag ?
if [[ ${line:$((${#line}-1))} == "{" ]]; then
# strip "{"
group=${line:0:$((${#line}-1))}
# do we have a match ?
if [[ ${group} -eq $1 ]]; then
match=1
continue
fi
continue
fi
# found close tag but still no match - continue
elif [[ ${line:0} == "}" && $match == 0 ]]; then
continue
# found close tag after config was read - exit loop
elif [[ ${line:0} == "}" && $match == 1 ]]; then
break
# got a config line return it
else
echo $line
fi
done < "$CONFIG"
for line in $(readconf "system"); do
echo $line
done
As you can see I try to just echo the lines at the moment. And here's the problem: It seems I have some " escape issues, if I run it I get the following output:
./parseconfig.sh
DATE_PREFIX="-I"
SSHFS_OPTS="-C"
EXT_FULL="full"
EXT_DIFF="diff"
EXT_CATALOGUE="catalogue"
DAR_OPTS="-v
-m
256
-y
-s
600M
-D"
DAR_NOCOMPR="-Z
'*.gz'
-Z
'*.bz2'
-Z
'*.zip'
-Z
'*.png'"
As you can see there are way to much newlines - which leads to problems when I try to use "eval" to initialize the variables.
I am sure I am missing something simple here, however I am looking for a solution for a few days now - maybe one of the bash gurus on this board can enlighten me ;-).
Thanks in advance
PS.: I am trying to do this in pure bash because the script also needs to run on embedded machines with very low memory like my router on which I don't have sed or awk or the like. I also know that I could for example just use different config files to circumvent the whole parsing - but I am just curious if this could work the way I like ;-).

Hi MrWeatherbee,
well yes, but I want to assign (eval) these lines to get variables out of them. Since the while loop is trapped in its' own subshell I need to return the lines into the parent one to be able to make these variables "visible" in the script itself.
Right. But I was trying to show you that the way you were going about it wouldn't work at a very fundamental level.
Without changing too much code just for a quick and dirty demo,
change:
# got a config line return it
else
echo $line
fi
done < "$CONFIG"
# got a config line return it
else
line_array=( "${line_array[@]}" "$line" )
fi
done < "$CONFIG"
numarrayelements=${#line_array[@]}
and then in the main program code, do this:
readconf "system"
for index in $( seq $numarrayelements ); do
line=${line_array[(($index-1))]}
echo $line
done
Using an array to collect the good lines from the function allows you to reuse them later for whatever purpose. Although other ways exist, you certainly don't want to do what you originally did.
Edit:
I posted the code with an incorrectly referenced variable and had to fix it.

[SOLVED ]makepkg asking for pacman-color binary

After upgrading pacman to 4.1 I'm getting this error every time I run makepkg:

echo $PACMAN
pacman-color
I guess I've forgotten to edit some file that I changed when using pacman-color-testing from the AUR.
EDIT: Indeed, I forgot to edit my .zprofile that used to export PACMAN as pacman-color. Solved now
Thank you, Allan

[SOLVED] GRUB crashed after pacman -Su

Hello all,
I did a system update about 2 hours ago, I did pacman -Syy and pacman -Su. Every thing looked normal.
Restarted and system crashes right in GRB, it doesn't even shows the menu or error message, it just fills the screen with "GRUB GRUB GRUB GRUB GRUB GRUB GRUB".
I checked the disk, partition tables are ok, and the whol HD looks ok, no errors at all (checked with system rescue cd, a gentoo live cd).
I also mounted the boot partition, all files seem to be ok, grub menu, etc..
/grub/menu.lst was modified today, but looks ok.
Any Idea of what could happen?
How to solve it?
Should I try to replace grub?

Thank you hcjl and demian.
Problem solved after GRUB re-install.
Here is the procedure (resume from hcjl links) I made, just in case someone else needs it:
1- Download the arch iso and write it to cd or dvd
2- Run the cd, login as root
3- Mount arch and boot partitions:
-Find boot and arch partitions with
fdisk -l
Create a directory where you would like to mount the arch partition, then mount it:
mkdir /mnt/arch
mount /dev/<device-or-partition-name> /mnt/arch
4- Changing Root:
cd /mnt/arch
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
Mount the boot partition:
mount /dev/<device-or-partition-name> boot/
And change root:
chroot . /bin/bash
5- Install GRUB on hd0 (first hard drive):
# grub
grub> setup (hd0)
6- Exit all, reboot
That fixed my problem, and preserved my original GRUB menu (I did a backup of broken GRUB, but it was nor necesary)
Thank you all for your help.

OK, that gave me a segfault, so
I downloaded the package and copied the folders to root.
no pacman works but gaves me this errors afterwards:
pacman-3.4.1-1: description file is missing
pacman-3.4.1-1: dependency file is missing
pacman-3.4.1-1: file list is missing
how do I solve this?
BTW: should I make a bug-report??
EDIT: any package I try to instal I get this error:
erro: não foi possível abrir o arquivo /var/lib/pacman/local/pacman-3.4.1-1/depends: Arquivo ou diretório não encontrado
(it's in portuguese but i think its understandable)

hi, really sorry as I said I'm somewhat of a newbie, was waiting to see what you guys thought might be relevant so I could tell you what I've got, here goes:
graphics card: nvidia geforce GTX660.
DE/WM (I assume is desktop environment): gnome
unsure about how I start X (sorry I understand I am a newbie)
oh and everything does seem to be hanging, ctrl-c does nothing.
there were no messages from the update, I checked pacman and didn't see any warnings, (is there any kind of log I can check in case I missed something?), I've chrooted into the disk through the installation medium to reinstall the graphics card drivers (as suggested here https://bbs.archlinux.org/viewtopic.php?id=153206)

[Solved] How to reduce "Pacman -Qe" result by dependency?

I know "Pacman -Qe" will list which all package I explict installed.
But, I want to reduce the result by dependency.
For example:
If I've install xpdf & xpdf-Chinese. I want to reduce the report to xpdf-Chinese.
Because there is a dependency of xpdf in xpdf-Chinese.
Ans: pacman -Qt
Thank you, it works.

I think this is what you want:
-t, --unrequired
Restrict or filter output to packages not required by any currently installed package.

[SOLVED] Xscreensaver outputs log text above active screensaver

I'm having problems understanding why this happens. Running the latest xscreensaver and whenever I choose to preview or run a screensaver I get an ugly yellow log-like output either in background or foreground of the active screensaver. Only using
xscreensaver-demo
to change settings and starting the xscreensaver daemon from my ~/.xinitrc. A screenshot:
I've had this problem for a while, so if you people have an idea please share it. Thanks!

Problem solved: had to change the following X resource setting in ~/.Xresources from true to false:
xscreensaver.verbose: false
. Never mind!
