bash question

[Ari Moisio]

Hi!

  Try variable $?.

  You can test exit codes with following scriptlette

#!/bin/bash
$*
echo Exit=$?


  In scripts you can also use if-statements: if program return zero on
exit it is true, otherwise false.

  There are also following shortcuts

cmd1 && cmd2

  Cmd2 is run only when cmd1 return zero.

cdm1 || cmd2

  Cmd2 is run only when cmd2 returns non-zero.
