Shell

Run commands simultaneously

Solution

• Suppose I want to run 3 commands simultaneously (Like submitting 3 Hadoop jobs)

  sh ./test1.sh &
  sh ./test2.sh &
  sh ./test3.sh &
  wait # You might want to wait for the above command to complete then proceed
  

• & lets the program to run in background

• Note, if you want to kill it, you will have to find its pid and run kill pid
