I am suggesting a much simpler utility I just wrote. It's currently called par, but will be renamed soon to either parl or pll, haven't decided yet.

https://github.com/k-bx/par

API is as simple as:

par "script1.sh" "script2.sh" "script3.sh"

Prefixing commands can be done via:

par "PARPREFIX=[script1] script1.sh" "script2.sh" "script3.sh"

It can be done with simple Makefile   sleep           sleep   subst sleep               echo    done    Use -j option     make -j sleep3 sleep2 sleep1 sleep 3 sleep 2 sleep 1 sleep1 done  sleep2 done  sleep3 done    Without -j option it executes in serial     make -j sleep3 sleep2 sleep1 sleep 3 sleep3 done  sleep 2 sleep2 done  sleep 1 sleep1 done    You can also do dry run with  -n  option     make -j -n sleep3 sleep2 sleep1 sleep 3 sleep 2 sleep 1

This bash script is for N parallel threads  Each argument is a command   trap will kill all subprocesses when SIGINT is catched  wait  PID LIST is waiting each process to complete  When all processes have completed  the program exits      bin bash  for cmd in       do     echo  Process    cmd   started      cmd  amp  pid      PID LIST     pid     done  trap  kill  PID LIST  SIGINT  echo  Parallel processes have started    wait  PID LIST  echo echo  All processes have completed     Save this script as parallel commands and make it executable  This is how to use this script   parallel commands  cmd arg0 arg1 arg2   other cmd arg0 arg2 arg3    Example   parallel commands  sleep 1   sleep 2   sleep 3   sleep 4    Start 4 parallel sleep and waits until  sleep 4  finishes

To run multiple commands just add  amp  amp  between two commands like this  command1  amp  amp  command2  And if you want to run them in two different terminals then you do it like this   gnome-terminal -e  command1   amp  amp  gnome-terminal -e  command2    This will open 2 terminals with command1 and command2 executing in them   Hope this helps you
