  You had

  ps -ef|grep "$user.*$app_name"|grep -v grep|sed -e 's/"//g' -e 's/.* script//'

  If you're using all GNU tools, you can improve that shell command a bit:

  ps --no-header --user "$user" --format command | grep "^$app_name" | sed 's/"//g;s/.* script//'

  • No grep for user (which may be output numerically under some conditions)
  • --no-header and --format mean you get only what you want out of ps
  • No grep -v to remove grep
  • No -e on the sed commands
  • Combined the sed commands into a single sed exp

    We're on Solaris. Many tools and options I took for granted on *nix systems simply aren't available. For example, the ps command does recognize the --no-header or --user options.

    Other annoyances: tar doesn't recognize the z modifier and the absolute worst: grep doesn't recognize -r. No recursive grep. The options are either doing a find and piping the results to grep or using ack [cpan.org] (the latter of which is lovely, I might add).

      can't you simply install some packages? sunfreeware.com is a good place.

      Anyway my point was: don't forget /proc and magic ps ;) perl -lpe 's{\0}{ }g' /proc/*/cmdline

      cheers --stephan p.d at least if you have a decent support for it always worth to remember.
