in reply to List standard Unix error codes

Here's a way to get the symbolic names as well:
#!/usr/bin/perl use strict; use warnings; use Errno; foreach my $err (keys (%!)) { $! = eval "Errno::$err"; printf "%3d %20s %s\n", $! + 0, $err, $! } __END__

Note that the names are somewhat portable (it improves if you stick to the POSIX names), but the numbers and descriptions are not portable. Not even from one Unix to the other.
