warn
LIST
This function produces a message on
STDERR
just like
die
, but doesn't try to exit or throw an
exception. For example:
warn "Debug enabled" if $debug;
If the message supplied is null, the message "Something's wrong" is used. As with die , a message not ending with a newline will have file and line number information automatically appended. The warn operator is unrelated to the -w switch.
