die

Synopsis

die "something went wrong";
die "Error at $file line $line\n";
die $exception_object;
die;                              # re-raises $@

Description

Raises an exception, terminating execution unless caught by an eval block or a try/catch construct.

If called with a string argument, raises that string as the exception message. If the string does not end with a newline, Perl appends at FILE line LINE. If called with a reference (e.g. a hashref or blessed object), the reference is propagated as the exception value in $@.

When called with no arguments (or an empty string / undef), re-raises the current value of $@. If $@ is also empty, dies with "Died".

If there is an active try block (from use feature 'try'), the exception is caught and execution transfers to the catch block instead of propagating.
