Greetings!I am not completely understanding how perl parses quotes. Here is the line I want to execute: exec "$command $cmd_msg"; The variable $command is an executable shell script "test.sh" The problem comes in the $cmd_msg variable. This contains a line from my log file: Nov 13 11:54:31 fw-3 sshd(pam_unix)[19906]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=82-148-208-172.fiber.unet.nl The shell script blow up on the parenthesis: sh: -c: line 0: syntax error near unexpected token `(' How can I quote the exec line above so what gets passed to /bin/sh is the log file line contained in double quotes?
Simplistic, but possibly risky: exec qq[$command "$cmd_msg"]; Much better, IMO: exec "$command \Q$cmd_msg"; Or even better, bypass the shell by using the list form of exec(): exec $command, $cmd_msg; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
