Can somebody explain the difference between this 2 system calls ? system "grep 'fred flint' buff"
This one asks the shell (/bin/sh) to run the command "grep 'fred flint' buff".
system "grep", "fred flint", "buff"
This one asks grep to run, giving it the two arguments "fred flint" and "buff"; there's no shell involved. Does that clear anything up for you? --Tom Phoenix Stonehenge Perl Training -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
