Whenever I've had to execute system or shell commands, I use the backtick operator, the system command, or filehandle half-pipes (or whatever they are called :). And I've always seen these recommended whenever someone asks how to do that.
But recently, I saw the use of the Shell.pm module: use Shell qw(who); my @who = who(); and I wondered what the (dis)advantages of using it are, and why no one uses it anymore? Chris -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
