How to stop a shell script running in the background?-CodePudding

I run the first shell script and it starts printing. I pause the execution using CTRL-Z. I give the bg command and the first shell script starts running. I run a second shell script. Now both the scripts are printing simultaneously. Now I need to stop the execution of the first shell script only and the second shell script should continue printing. What commands can I use to do this ?

CodePudding user response：

If you catch the PID of each execution you can stop one of them with kill command

myCommand & echo $!

You can write a script for run the two command and catch the PID of each of them and stop the one you want with kill command.

You can stop command2, send the signal to stop command1 and then let command2 continue

$ command1&
[1] 42510
$ command2
^Z
[2]   Stopped                 command2
$ jobs
[1]-  Running                 command1 &
[2]   Stopped                 command2
$ kill -STOP %1

[1]   Stopped                 command1
$ jobs
[1]   Stopped                 command1
[2]-  Stopped                 command2
$ kill -CONT %2
$ jobs
[1]   Stopped                 command1
[2]-  Running                 command2 &
