linux - Bash: run an executable file in background

Question

I have an executable file that contains a long loop, so I want to run it in background, how do I do that with bash script in Linux?

I know one way is Ctrl + z, then I type bg, how to simulate these key pressing in bash script?

Answer 1

Any executable in linux can be run in the background as follows:

 $ ./yourExecutable.exe&

Add the & character at end. (Assuming yourExecutable.exe is in the current working directory)

How to kill it later on?

$ ps -ax | grep yourExecutable.exe

You will get an output like:

9384  pts/7    S+     0:00 grep yourExecutable.exe
25082 pts/7    T      0:00 yourExecutable.exe&

Kill the second process using SIGKILL. That is the one you executed in the background.

$ kill -9 25082
