(Ovid - how to find odd answers) Re: how to make a password dissapear?by Ovid (Cardinal)

I recently answered this question on the beginners-perl mailing list. I think you might find the reponse very helpful.
I've never used that before but some may be curious how I found it. Here's the trick:
perldoc perltoc > perltoc.txt
That sends the perltoc (Perl Table of Contents) to a text file. I sometimes scan through this file to pick up new tricks. When I see something that interests me (such as "password"), I scan through the relevant entries. In this case, I saw the following entries:
[snip] How do I clear the screen? How do I get the screen size? How do I ask the user for a password? How do I read and write the serial port? [snip]
The one about asking a user for a password looked useful, so I typed in:
perldoc -q "How do I ask the user for a password?"
That actually gave a lot more information than what I sent you, so you should give it a try :)
The '-q' options stands for "FAQ keyword", but it can just as easily stand for 'question'.
