Newb bash script

Well I've had linux for about a year or so now....Well I suppose longer than that but I didn't use it for a while but here I am full time user of Linux for about a year now, wahoo!
Anyways, I suppose its time to dabble into some coding so I can understand those pesky pkgbuilds when I wanna change them...
Basically right now I have the linux client Team Fortress 2 dedicated server installed and it has a command to run which starts the script.  I made a script in /usr/bin that I can call on quickly with just 'tf2server' to fire up the server when I want.  It already has the options in that script such as the players and which map to load.
./srcds_run -game tf +maxplayers 5 +map
is basically the line that it calls. What I want to do though is instead of having to go to the folder where it is and running that command with different options when I want to each time I'd like to be able to just do something like...
tf2server cp_well
for example, and then it would use well for the map.  I know that in terminal you can type --help on most commands and it will show you usage, so basically my question is....Is there a guide, or someone willing to give an example on how I can accomplish this? I'm assuming it will only take bash and some wildcards of some kind to do.
Help is appreciated

Unless your script is explicitly cd'ing into the directory for 'srcds_run', then attempting to invoke the command found in the current directory is probably not what you want.  If this is the case, I'd either have the script change to the correct directory itself, or ensure the path to srcds_run is in your $PATH and remove the leading "./".  When running a script, the current directory is that which the script was invoked from and not that which the script is located.
To accept options as in your example is quite simple:
./srcds_run -game tf +maxplayers 5 +map $@
$@ evaluates to the argument(s) specified.  So, assuming the '+map' option takes the name of a map as an argument:
tf2server cp_well
Should work fine.  With this you can also specify any additional settings for the server.  E.g.,:
tf2server cp_well +timelimit 30
(Note: I know nothing about Team Fortress. '+timelimit' probably doesn't exist; I'm just making things up )
If you're interested in learning shell scripting, Advanced Bash Scripting (PDF) is an excellent resource.
Hope this helps.

  • Newbie bash scripting help!

    Hello,
    I would like some help with a simple script.
    I have say 10 text files (***.txt) in a directory.  I want to make each *** into a subdirectory, insert the respective ***.txt file into that subdirectory as well as insert three other files into each subdirectory.
    I then want to create a loop that will run a seperate script, which I already have, on each folder.
    Thanks for any help

  • Iwl3945 and dhcpcd workaround - bash script

    I got tired of typing every command by hand all the time, so i made this simple bash script to do this for me...
    edit the script with your preferences and settings and run it as root. The script sets a static ip, and all the shizzle thats needed to have a workaround for the dhcp not working
    And im a newbie in bash programming, so please dont flame
    anywho, please give med feedback if theres something i could do different and better

    Correct me if I'm wrong, but you could simply add the rmmod / modprobe stuff and all that in PRE_UP='' in any of your netcfg profiles and the just run netcfg <profile>.

  • SQLPlus output within bash script

    Hey everyone, I wasn't sure if this should go here or in the SQL forum or the Linux forum, but here goes:
    Using Oracle10g on Linux, I'm using a bash script to run an sql script, but when I try to echo the results, it shows the output in a single line.
    Here's the script
    USERLIST=`sqlplus -s  / AS SYSDBA <<EOF
       set head off
       set verify off
       set feedback off
       SELECT username from dba_users;

    EOF
    `
    echo $USERLIST;And here's the output:

    Any help would be much appreciated, thanks.

  • Sending email using bash script

    Hello:
    I am working on writing a bash script to notify one or more users by email of certain events. Run from the Terminal command line, and having the script "echo" text of (what would be) a form letter with in-line variable expansion (i.e., ${VARIABLE}), all seems to work as anticipated. Eventually, I want cron to launch this shell script, and send an email to an "on-subnet" user (I have postfix enabled on my Mac, and there are multiple local user accounts).
    I found some stuff on the web about sending mail from bash scripts, and so I made a small little test script, that reads like this:
    #!/bin/bash
    VARIABLE[1]="The 12,345 quick brown foxes "
    VARIABLE[2]="jumped over the 67,890 lazy dogs."
    mail -s "a test email" jv << EOF
    This is a test:
    ${VARIABLE[1]}
    ${VARIABLE[2]}
    This is the last line of the test message.
    EOF
    echo "script completed"
    It worked... almost... It sent a local email to my postfix mail account that read like this:
    This is a test:
    The 12,345 quick brown foxes
    jumped over the 67,890 lazy dogs.
    This is the last line of the test message.
    EOF
    echo "script completed"
    So, I have two questions. First, the easy one (I hope):
    How do I delimit the end of the text, that I want to be the message body of the email, from portions of the script that follow said email text?
    Next question is a little more involved. You know how, in Mail.app, if you go to Mail Preferences>Accounts>Account Information, you can put multiple email addresses, comma-delimited, in the "Email Address" field? So, if a person entered "[email protected], [email protected], [email protected]" in this field, then, even though (s)he may be at home, and using their home ISP's mail server, (s)he could send an email apparently from either their home, work, or school email address. Of course, the mail headers clearly would show it came from and through their home machine and home ISP, but it would be displayed in the recipient's Mail client viewer as having come from one of [email protected], [email protected], or [email protected].
    I'd like to do something similar here, whereby the email (that is being sent to one or more local users' postfix account on my computer) would apparently be sent from "watchdog@localhost" rather than from "jv@localhost" like it seems to do by default. Whatever account the script is run from (or presumbably, whose cron tab is launching the script) is what the "From" address is set to.
    I'd rather not create an additional mail account, because I am using Mac OS X built-in accounts for the postfix mailboxes (I don't want to have to maintain a plaintext username:password file in postfix, and I don't want to create an additional user account on the computer).
    So, is there a way to specify an alternate "From" username when invoking the mail -s ${SUBJECT} ${RECIPIENT} command in a bash script? Or is there a different, alternate mail command that will let me do so? (please include a description of syntax and how I'd package the above message text for the alternate method).
    Thanks in advance, all!

    Hi j.v.,
    The > after EOF is just a typo (or may be added by the Discussion ?) and you must delete it; other > are prompts from the interactive shell. Andy's post shows an interactive use of shell, not a shell script (note the shell prompt % in front of the commands). A typical use of here document may look like
    command <<ENDOFDATA
    ENDOFDATA
    There must be no spaces before and after ENDOFDATA. The word ENDOFDATA can be EOF or any other string which is guaranteed not to appear in the text (the .... in the example above).
    You can modify the From: header by using sendmail command (postfix has it as a compatibility interface):
    /usr/sbin/sendmail -t <<EndOfMessage
    Subject: test mail
    To: jv
    From: watchdog
    This is a test:
    ${VARIABLE[1]}
    ${VARIABLE[2]}
    This is the last line of the test message.
    EndOfMessage
    There must be a blank line between the headers and the mail body.
    I assume that you send these mails only to users on your local Mac. Please do not send mails to remote users by using the sendmail command unless you know what you are doing completely.

  • [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.

  • Can't get conky-cli and bash scripts to both display in dwm statusbar!

    I'm trying to configure my dwm status bar to display some simple information using conky-cli and bash scripts. At first I tried just letting conky run the bash scripts (for network and volume state), but this increased my cpu usage by about 5%, which is significant considering I normally have 1-3% usage when idle. Also, I wanted to keep conky because it makes the display of certain information easy, such as cpu & RAM usage.
    The problem is I'm having trouble getting both to display side by side. Here are the relevant parts of my .xinitrc:
    network(){
    iwconfig wlan0 2>&1 | grep -q no\ wireless\ extensions\. && {
    echo wired
    exit 0
    essid=`iwconfig wlan0 | awk -F '"' '/ESSID/ {print $2}'`
    stngth=`iwconfig wlan0 | awk -F '=' '/Quality/ {print $2}' | cut -d '/' -f 1`
    bars=`expr $stngth / 10`
    case $bars in
    0) bar='[-------]' ;;
    1) bar='[#------]' ;;
    2) bar='[##-----]' ;;
    3) bar='[###----]' ;;
    4) bar='[####---]' ;;
    5) bar='[#####--]' ;;
    6) bar='[######-]' ;;
    7) bar='[#######]' ;;
    *) bar='[--!!!--]' ;;
    esac
    echo $essid$bar
    exit 0
    volume(){
    vol=$(amixer get Master | awk -F'[]%[]' '/%/ {if ($7 == "off") { print "MM" } else { print $2 }}' | head -n 1)
    echo Vol: $vol%
    exit 0
    conky | while true; read line; do xsetroot -name "`$line` `volume` `network` `date '+%a %m-%d-%Y %I:%M%p'`"; done &
    exec dwm
    (let me know if it would help to post any other files)
    For some reason when I run this I only get the network/volume scripts and date running, updating every second (I think). The conky line just doesn't show up. I don't know what could be wrong, since I didn't see any error messages.
    An even better solution would be to just have shell scripts to display CPU and MEM usage. I have a dual-core cpu, cpu0 and cpu1. I'd like to see both percentages if possible, or at least a percentage that is an accurate average of the two or something. In conky-cli I have something that shows:
    cpu0/1: xx% xx%
    Also, seeing RAM usage would help a lot. In conky it shows:
    mem: xx% (xxxMB)
    These are the ways I would like to have bash scripts show them, if possible, but I have zero skill in bash programming. I made this an option in case it's easier/cleaner/less resource hungry than a conky solution. Personally, if they're about the same in these aspects, I would prefer something with conky and the shell scripts because conky is so extensible, yet it's only flaw is executing scripts with minimal resource usage.
    Help?

    Thanks. I was thinking of using load average to save a few characters, but I didn't quite understand the numbers. I'll try that once I get to my Linux box, but could you please explain or post a link to something that explains load average (what's low, high, normal, etc.)?
    EDIT: I found a website that explains loadavg. I now have my dwm status bar displaying it perfectly (yay!). Now I just need to add a few more things like battery status, etc. and I might be done. I'll probably post here if I have more questions, though.
    Thanks for your help!

  • What do you think of my Bash Script? What about the error checking?

    Well what do you think of this Bash script
    It works
    I gave it some problems (i.e. unpluged the ethernet, messed up the URL's, uninstaled some programs...) to see if would report errors and stop or just keep going... But it did
    I just kind of thought up a way to do some error checking with the commands that I know.....
    What is a better way to do error checking?
    What do you think I should add/Do to this script?
    #!/bin/bash
    # Shell script to make a USB Tumb Drive for Flashing BIOS on a Lenovo Ideapad Y510.
    # This script needs to be owned and run as ROOT with the "sudo command"
    # i.e. sudo usbbiosflasher
    # If you have anyideas send me a PM on ubuntufourms.org my user name is HunterThomson
    # Name/Rename this script usbbiosflasher and save it to the ~/home directory.
    # Then run the command- chown root:root usbbiosflasher
    # Then run the command- chmod 755 usbbiosflasher
    # Then copy the script to the directory /usr/bin.
    # Run this comand to do that- sudo cp ~/usbbiosflasher /usr/bin
    # You also must have the program "mbr" installed
    # You can install the mbr program by running this comand in the shell on Ubuntu
    # sudo apt-get install mbr

    Personally.....  (this is just how I would have written it - if it works, then it's good enough for me though )
    I would change this whole block:
    verify="n"
    while [ "$verify" != y ]
    do
    printf "Do you have mbr installed... yes or no?"
    read AN1
    echo ""
    printf "You answered... $AN1 I have installed mbr. Is this correct... y or n?"
    read verify
    done
    echo ""
    if [ "$AN1" == "no" ]
    then
    echo "Install mbr now. Then run this script agin"
    exit
    else
    echo "contunuing script"
    fi
    To this much shorter code:
    MBR='/usr/bin/install-mbr' # Or where ever you expect it to be
    if [ ! -x $MBR ] ; then
    echo "mbr doesn't appear to be installed."
    echo "If it is installed, check it's location, make sure it's executable and then make sure the MBR variable in this script is correct"
    exit 1
    fi
    I wouldn't have used the checkXX variables for each stage:
    mkdir ~/usbbiosfiles
    if [ $? != 0 ] ; then
    #failed
    echo "Could not \make directory usbbiosfiles"
    echo "look above \for \info"
    echo "Fix the problem and run this scrip agin"
    exit 1
    else
    echo "Made directory usbbiosfiles... OK"
    fi
    There is an issue with the way you do your verifications - the user can never get out unless they answer 'y' or hit CTRL+C. Something like this gives them options:
    verify="n"
    while [ "$verify" != "y" && "$verify" != "n" ]; do
    echo "You need to answer 'y'es or 'n'o"
    read verify
    echo $verify | tr "[:upper:]" "[:lower:]" # This converts the answer to lowercase so replies entered in upper case will still work
    done
    if [ $verify != 'y' ] ; then
    exit 1
    fi
    One last thing I try to do in scripts... Declare all your binaries as variables at the start of the program, then execute the binary program by using the variable. For example:
    # Binaries
    TAR='/bin/tar'
    CP='/bin/cp'
    CHMOD='/bin/chmod'
    # Execute tar and chmod the created file
    $TAR cvzf /tmp/tarfile.tar.gz /etc/*.conf
    $CHMOD 400 /etc/*.conf
    This way, it's easy to change the path in future without having to hunt through the script if the paths change, and it also ensures you're calling the programs using the full paths to make sure you're not executing some strange variant or alias that someone has setup. If I use `chmod` 30 times in a script, and the path changes in the future or on a different system (`chmod` is a bad example cause it's highly unlikely to change, but you know what I mean), then all you need to do is update the variable at the start of the script, and it all works again without having to script-hunt and change it 30 times.

  • /etc/rc.d/network: bash script: how to find out, if there was an error

    hello!

    but there is a big problem: starting network success' every time, whether there was an error or not:

    can someone help me please? how can i realize  that "::Starting Network ..." also fails and the script returns an exit status 1?
    thanks for your help, maybe we can improve the script. but i'm not a geek in bash!

    try using netcfg to start the wireless profile, that should keep you happy until the new network scripts are unleashed... which won't have this problem.

  • 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...

  • HOW DO I  RUN A UNIX BASH SCRIPT FROM JAVA??

    HI. Here's a tricky little problem i have. There's a unix bash script that has some commands in it, that manipulate a file. It appends a certain string variable to a file called users. The users file is an ordinary text file.
    I know this script to work perfectly, when i invoke it like this directyl from the command line: ./addusers.sh
    or even: bash /downloads/selinux/policy/addusers.sh
    Now, i have a java program, and its meant to just execute that script. It doesnt throw any Exceptions at runtime. But when i look at the users file, and expect it to have an extra line that was the string variable, the file is UNTOUCHED!
    Again, direct command line invocation works, but not from java. Here's what my invocation from java looks like:
    Process p = Runtime.getRunTime().exec("bash downloads/selinux/policy/addusers.sh");
    The strange thing is, i tried a different bash command. I tried:
    Process p = Runtime.getRunTime().exec("mkdir /temporary");
    and this worked!
    so why not the other one??
    I cant figure it out.

    You say:
    bash /downloads/selinux/policy/addusers.sh
    And you say in Java:
    Process p = Runtime.getRunTime().exec("bash
    downloads/selinux/policy/addusers.sh");
    As if a leading / would be missing from the Java
    version...nyix says:>
    ...OK sorry about that. i DO have a / in front of the downloads.... section in the java method. So its:
    Process p = Runtime.getRunTime().
    exec("bash /downloads/selinux/policy/addusers.sh");
    HELP please?

  • How can I execute a bash script by double clicking in finder

    Hello!

    Thanks Johann

    Add the suffix command in your script name. E.g. Script.command.

  • Bash script to insert item in a alphabetical list

    I would like to use a bash script to insert a new "source" file into a list of sources which occurs within another file.
    The file in question is quite long and contains many other things. However the list of sources abides by the format below.
    [snip]
    SOURCES = \
    _add_datasource_.m \
    _add_line_series_.m \
    ylabel.m \
    ylim.m \
    zlabel.m \
    zlim.m
    [snip]
    How might I insert a new source file in alphabetical order. I'm assuming there is a fairly simple script to do such.
    TiA

    #!/usr/bin/env bash
    if [[ $# != 1 ]]; then
    echo 1>&2 "Usage: ${0##*/} fileto_insert_inSOURCE"
    exit 1
    fi
    MAKEFILE=Makefile.in
    TMP=/tmp/tmp.$$
    awk -v new="$1" '
    /^SOURCES =/ { in_src = 1 }
    in_src && ! done && $1 > new {
    # New file goes here
    printf(" %s \
    ", new)
    in_src = 0
    done = 1
    in_src && ! done && ! /\$/ {
    # New file must go after the last entry.
    # Put  on old last entry.
    printf("%s \
    ", $0)
    # replace current $0 with the new file.
    $0 = sprintf(" %s
    ", new)
    done = 1

  • Conky doesn't display bash-script variables (array)

    I've been playing around with Conky and a bash script of mine. Unfortunately Conky displays only static text and not the array-variables in my script.
    In my script:
    ...some code here...
    echo "Static text: ${Variable[1]}"
    In my conkyrc:
    ...some code here...
    ${exec ~/Test/test.sh}
    The result is: "Static text: ". When running the script from the command line everything is fine. I've also tried with exec, execi, execp, texeci to no avail. Any ideas?
    Edit: I had to be more specific.
