Hi fetaelin,

Use backticks instead.

Expand|Select|Wrap|Line Numbers
  1. my $x = `run_a_script.sh`;
  2. my $y = `ls -la`;
  3.

to expand on Millers reply....

system() does not return output, instead it returns the exit status of the command/application. To capture output use backtiks `` or the qx// operator.
