I am trying to execute a shell script from cron tab ..

that shell script works fine .. when i am executing directly in command line .. like

sh out.sh

it works fine .. but when i am set cron for this shell script its not working

my shell script : out.sh:

#!/bin/bash
firefox "http://localhost/acceptance/selenium-main/shell.php"

it will opens that shell.php webpage in firefox browser ... its works fine when executing directly from CLI

..i an setting cron job like this 

sudo crontab -e

then

23 13 * * * bash /usr/share/nginx/www/acceptance/selenium-main/out.sh

this was not working ..

i even tried 

33 13 * * * /usr/share/nginx/www/acceptance/selenium-main/out.sh

The big difference between running something in cron and from the command line is that your profile is run for your shell, so all the environment variables needed by your script are set correctly, but cron uses a naked "profile-less" shell.

Try using a script that sets all the environment variables it needs before executing the whatever the script does, so its "self contained".

How about

php /path_to_localhost/acceptance/selenium-main/shell.php

If it is just producing a report and has no user interations, just run the script. You do not need a browser to run php scripts.

It looks like the behaviour of cron when configuring GUI applications. Try creating a wrapper script like,

wrapper_script:

export DISPLAY=:0.0
xhost + 2>>/tmp/err.log
firefox "http://localhost/acceptance/selenium-main/shell.php" 2>>/tmp/err.log

Add cron entry as,

33 13 * * * bash /path/to/wrapper_script.sh

Try to use absolute path:

23 13 * * * /bin/bash /usr/share/nginx/www/acceptance/selenium-main/out.sh

Also try to run bash in login mode if something doesn't work right.

23 13 * * * /bin/bash -l /usr/share/nginx/www/acceptance/selenium-main/out.sh

That would try to fix other variables like PATH. If not, try to explicitly set it in your script, or just use absolute paths everywhere.
