In general  I use nohup CMD  amp  to run a nohup background process  However  when the command is in a form that nohup won t accept then I run it through bash -c         For example   nohup bash -c   time   script arg1 arg2  gt  script out   amp  gt  time n err out   amp    stdout from the script gets written to script out  while stderr and the output of time goes into time n err out   So  in your case   nohup bash -c   time bash executeScript 1 input fileOutput  gt  scrOutput   amp  gt  timeUse txt   amp
