And as a side-note, something I learned the other day for error handling in system calls :
The special variable $? returns a boolean value for success or fail on system calls. So the above snippet performs a reliable "or die" check on your command. A handy one to know, especially as system tends to be a little unreliable in terms of error checking / return values when using a straight die, IMHO.
Update: as per comments below, not a "boolean" in the strict sense of the word. Call it an "azatoth boolean" :) Azatoth a.k.a Captain Whiplash Make Your Die Messages Full of Wisdom!Get YOUR PerlMonks Stagename here! Want to speak like a Londoner?
