in reply to Interesting line which I read from Monk's snippets

I need to try $0 first!

If I am calling the script from far away (for example in windows: C:\perl\bin\eraseme.pl) , then $0 has also the path attached to the name... ($0 eq 'C:\perl\bin\eraseme.pl'). So, it would not work as expected.

I should first, get rid of the path...

$0=~s/^.*[\\\/]//;

UPDATE: see a better way with liverpole's comment.

An easier way to get rid of the path is:

use File::Basename;
my $iam = basename $0;

I used to use a regex substitution instead, and my fingers still "remember" the sequence: (my $iam = $0) =~ s,.*/,,;


But when I started coding in Perl for Windows in addition to (Li|U)n[ui]x, it was unwieldy to use a regex which accounted for all the different pathname symbols.  Someone told me about the File::Basename method, and I've used it ever since; it's easier to remember, easier to type, and part of the standard Perl distro on both systems.
