Software :: Running A Zip Command In A Bash Script?
Jul 7, 2010
writing bash scripts (wrote my first one this Sunday) and I'm trying to zip a group of files. It has to be in zip format so alternatives like tar won't work here. I have my script in a folder which has a bunch of Sub-directories in the format "Lab 3" "Lab 5" "Lab 6" etcWhat I'd like to be able to do is take all of the files (just the contents not the folder itself) in the "Lab 3" Folder and put them in Lab3.zip. I'm really close but no matter what I try I keep getting the folders put into the zip file instead of the Folders contents
Code:
#!/bin/bash
LabNum=(3 5 6)
[code]....

Is running a command in the Alt+F2 prompt possible in a bash script?I need this for a launcher for gnome-shell.For it I have written a little script to check if the process gnome-shell is alive and act accordingly.The script works fine, I just don't know how to write "debugexit" to the Alt+F2 prompt, as that is the only decent way I have found to shut gnome-shell down and going back to gdm desktop smoothly.

In windows command prompt, F8 key can cycle through your previously entered commands i.e say you enter "ping google.com" and then "pushd <dir>". Next when you type p and then press F8 brings pushd and next F8 brings ping command. You can then hit enter to execute the corresponding command i.e ping in this case.Is there anything similar in Ubuntu Terminal running bash? Very handy to get back previously entered commands.

Is there a way to use exec, but if exec fails to go on with the script?
Example:
Code:
#!/usr/bin/env bash
exec startx
echo "Starting of X failed"
If startx fails, the echo will be seen on the screen. I tried all kind of stuff, but guess it ain't of much use to post it here. I searched the web, but searching for "exec and bash" in one sentence does give results which are not what i am looking for.

below are the details of my system. I have bash as my current shell, some really common commands aren't working.
Do I need to do a re-installation of bash? Or how do I install a selection of bash commands which I need? (for example a subset of [URL])
Code:
root@sdptfw:~ # uname -a
Linux sdptfw.sdpt.co.za 2.4.36 #1 Tue Jul 22 13:13:24 GMT 2008 i686 i686 i386 GNU/Linux
root@sdptfw:~ # echo $SHELL$
/bin/bash$

I presume there is something in the JWM window manager - or Puppy Linux Lupu 5.01 itself that is conflicting with the normal loading of GMPLAYER....
I would like to know how to troubleshoot, and fix this problem if possible (even a workaround would be great).

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?

I'm writing a bash script to move files around based on various bits of metadata. For a few reasons, this script will be run regularly both from the terminal, and from the nautilus-scripts folder ("graphically", if you will). What I'm stumped on is having the script defer outputs based on which mode the script is running in. For example, how can I have the script know whether to echo error statements, or pump them out to zenity based on the method of invocation?

Trying to write a script for desktop launchers that are adaptable to screen resolution. Ideally, the program should:
1. Determine screen resolution:
if "a" use xdotool options window size 1305 x 869 px and move to 135,0
if "b" use xdotool options window size 1545 x 1019 px and move to 135,0
2. Check if program running:
if no, open program, and use "a" or "b" placement options, focus window
if yes, focus window
3. Close script and leave program open (if possible).
Problems arise when trying to use the script on programs that run from and hog the terminal
(e.g. brasero, gcalctool, nautilus)
Here the script will load the program, and nothing else (probably because it still occupies the terminal as it runs)
Code:
gcalctool && xdotool search "calculator" windowmove 135 0
This next command will cause the program to load, move, but it keeps focusing itself like xdotool is running the windowmove function constantly - it keeps focusing itself until script stopped.
Code:
gcalctool & xdotool search "calculator" windowmove 135 0
This had the same effect as the above code, but seems to work as a conditional subscript running when the process is running in the terminal - it just goes infinitely.
Code:
while [1] ; do xdotool search "calculator" windowmove 135 0 done exit
Is there some kind of "if, then" or "while, do" or some kind of conditional I can put in to the script ensure the window is moved only once if the program is running within the terminal? Is there a way to remove the program from the terminal from the script once it's been called?

so I wrote a small script that pretty much just takes in two numbers and counts from the first to the second, e.g.
unknown-hacker|544> count.sh 1 3
1
2
3
My problem is I want to make it so that if you input invalid parameters, such as non-numerical characters, more than 2 numbers, etc., you'd get an error message

I've been trying to write a bash script called runSorter.sh that runs an executable that also takes in some parameters and outputs the results to a text file. The executable, sorter, takes in a number parameter. I want to make it so that you can input as many number parameters into runSorter.sh as you want and it will run the sorter executable for each one. So far, what I have looks like this:
#!/bin/bash
args=("$@")
INDEX=0
if [ -z args ]; then
echo "Error"
else
while [ $# -gt $INDEX ]; do
NUM=${args[$INDEX]}
echo $NUM
echo ./sorter $NUM
let INDEX=INDEX+1
done
fi
My problem is that when I run ./run-sorter.sh 100 on my terminal, it just prints this to the screen:
./sorter 100
How can I have so that it properly executes sorter and outputs everything to a text file?

I have a bash script that messages the user periodically. Is there any way in the script to check if the screensaver is running, so the script doesn't spam messages while the user is away? The xscreensaver process is always running in the background, I've noticed.

I'm having trouble trying to make a script. What I want to do is check if xScreenSaver is running in my user account. If not, run it. If it's running, kill it.
So this is the script I've made:
Code:
The problem is that I've echoed the output of $(pgrep -u $(whoami) xscreensaver) and it always seems to add 4 numbers to the pid, even if the pid doesn't exist. What do I mean by "doesn't exist"? That no xscreensaver is running in my user, and if I run pgrep -u $(whoami) xscreensaver in bash, I get not output, but if I run the command though the script, I get (for instance) 4050. If I run it again, I get 4054, and again 4058... etc. What the hell is going on with that?

We have a custom app that runs on boot on some older hardware running DSL linux, and their startup manager was quite simple. We purchased some newer Asus eeebox's which run xandros and things are quite stable and run nice with 1 exception.The application only runs from the root (/) location. This box auto logs in as 'user' and there is a /home/user/.kde/Autostart folder where you can stick scripts to run at boot. So I have a start.sh script, and with little bash programming tried things such as;
sudo cd /
sudo /startapp.pl
but the errors start spewing with the basic;can't find data/xyz as it's looking in the local.I thought there was a basic cwd (change working directory) but everything I try just forces the run from that location.Any ideas or suggestions are appreciated, but things like can you change the code, etc. can't be done, so it must be a programming thing. The only other thought I had but not sure, can you do a cronjob with @boot or something, that when the box starts, it can run this job as root and fire off?
