Perl Programming/Keywords/die
The die keyword
editThe die comment raises an exception. If called inside an eval(), its message is stuffed into $@, and eval() returns with the undef. If the exception is outside of all enclosing eval()s, the uncaught exception prints LIST to STDERR and exits with a non-zero value. For a specific exit code, exit should be called.
Syntax
edit die LIST
Examples
editchdir '/usr/spool/news' or die "Cannot change to directory spool: $!\n"
