I want to create an hour glass on unix terminal using perl but without using Perl/Tk or pTk.

I never understand questions of the for "I want to do X, without using Y", where Y is an obvious way of doing X.

Perhaps you want to use Java. That avoids using Perl, Tk and pTk.

Yeah, I could give a different answer, using Perl and some other module. But then I bet your reply will be that you don't want to use that module either.
