Re: Get My Own Name

Yep. At first blush if you use $0 that will give you the name of the script being executed. But be careful. Let me show you a few case studies.

Invoking a script via the interpreter

Consider the following very simple script:

#!/usr/bin/perl -w 
print $0,"\n";
[download]

If I invoke it as


perl testzero.pl
[download]

sure enough it prints testzero.pl to stdout. Let's add a wrinkle! If I execute it as perl /home/peter/testzero.pl then then entire path name will be printed to stdout.

chmod'ed script

If I do a chmod 755 testzero.pl on my hapless script (assuming *nix environment here) then I have a similar problem. Executing


./testzero.pl
[download]

will yield ./testzero.pl to stdout and so forth.

In summary, hes you can get the path name of the script being executed but make sure you understand all of the implications.

There is also the interesting ( althought not relevant to the OP ) case of doing: `perl -e 'print "My name is $0.\n\n";'` [download] which produces: "`My name is -e.`" --`tidiness is the memory loss of environmental mnemonics`	[reply] [d/l] [select]
