Hi,
I set the script to run in background using
/bin/bash /home/user/script.sh Argument &

the script appeared in ps aux
root 1189438 0.0 0.0 12724 3060 pts/0 S 12:39 0:00 /bin/bash /home/user/script.sh Argument

Maybe the script terminated.
Would be nice to see the actual script.

you cannot check a process which is already terminated, but you can add some logging to that script to see how does it work (next time).

Not enough information. In addition to the above.

Although your script is running in the background it is still attached to its parent process. A common mistake is to close the terminal or if it is a remote connection to close the session. Using nohup or using screen will detach the process.

Unless you started it with "nohup", as soon as you closed that terminal window, that script closed. So if you rebooted your PC (or even just logged out), it's gone. As said, you're not showing us the script or giving us any details.
