If you want to avoid the shell messing up your arguments, you could try the 'indirect object'-form of exec. `my $cmd = '/usr/bin/tcpreplay'; # or whereever exec {$cmd} ($cmd, '-p', $pps, '-i', $eth); # and so on...` [download] Note there is no comma after the first arg to exec. With this form exec will not use the shell and pass the list of args unchanged as argv[] to the command. This means you have to supply a value for `argv[0]`, too (something one might forget coding too much perl...) Hope this helps....	[reply] [d/l] [select]
