[SOLVED] Check if Firefox Running in Linux Bash

[niccholaspage]

Another question about the Linux Bash.
I setup a Portable Version of Firefox for Linux with a simple script.Now if the user has a normal copy of firefox running and opens up the Portable Version,The Portable version will use the profile on the computer.Can I somehow check if firefox is running and if it is I can show A Message about this but if it isn't just start firefox? And here is the code I got to start Firefox up portably:

#!/bin/sh

./AppLinux/run-mozilla.sh ./AppLinux/firefox-bin -profile ./Data/profileIt just executes Firefox with a profile in the folder.This is an easy fix probably.


EDIT:fixed.scroll down.

If exit value is "0", it is running, else, not running.


ps -e | grep "firefox"

Ugh...Can you tell me how to do something like this:

check=ps -e | grep firefoxI could probably do this if the command had no spaces.Please guide this stupid guy...

check=`ps -e | grep "firefox"`

should work (note, those are back tics, not quotes)

Or you could just run it, and check the variable $? right after.

Thanks so much!

Now it says Firefox is open any time I run the script.Here is the code right now:


#!/bin/sh
check=`ps -e | grep "firefox"`
if check=0
then
zenity --info --text "Please Close any Firefox Proccesses"
else
./AppLinux/run-mozilla.sh ./AppLinux/firefox-bin -profile ./Data/profile
fi

why don't you do it all for the user


#!/bin/bash
pgrep firefox 1> /dev/null && pkill firefox
./AppLinux/run-mozilla.sh ./AppLinux/firefox-bin -profile ./Data/profile

Killall will force the application to quit.I don't want it to do this.

Note that the normal purpose of doing ./some_file is to provide a path for the shell to look up the executable you're referencing. Normally, there's no reason to use the ./ if you're just referencing a file (e.g., in the parameters to another command).

#!/bin/sh
check=`ps -e | grep "firefox"`
if check=0
then
zenity --info --text "Please Close any Firefox Proccesses"
else
./AppLinux/run-mozilla.sh ./AppLinux/firefox-bin -profile ./Data/profile
fi

You probably want to check the exit code of the grep command, if it is 0 then firefox is found in the output of ps -ef, without the grep command, that's why I added the grep -v grep to the command


#!/bin/sh
check=`ps -ef|grep firefox|grep -v grep`
if [ $? -eq 0 ]
then
.....

Thanks! Now it works great.
