Run three shell script simultaneously

you want this?

$ sh -x script1.sh & sh -x script2.sh & sh -x script3.sh &

Update explanation :

  • Run each script in background mode so that next command is run without waiting for current command to complete.
  • '&' makes the scripts run in background so that prompt does not wait for it to complete
  • '&' also can be used to chain commands on one line similar to running commands one by one on command line.

With GNU Parallel you can do:

parallel sh -x ::: script1.sh script2.sh script3.sh

If the scripts are executable then you can even do:

parallel ::: script1.sh script2.sh script3.sh
