No. There is no such thing. The standard answer to this in the Perl FAQ (old versions) was: 2.32) How can I convert my shell script to Perl? Larry's standard answer for this is to send your script to me (Tom Christiansen) with appropriate supplications and offerings. :-( That's because there's no automatic machine translator. Even if you were, you wouldn't gain a lot, as most of the external programs would still get called. It's the same problem as blind translation into C: you're still apt to be bogged down by exec()s. You have to analyze the dataflow and algorithm and rethink it for optimal speedup. It's not uncommon to see one, two, or even three orders of magnitude of speed difference between the brute-force and the recoded approaches.

Hello When you say shell, do you means bash, csh, tcsh, ksh, zsh, or what? There is no automated way to convert from any of these shell languages to perl that I know of. The simplest way would be to look at the script, figure out how it works, and then rewrite it in Perl. Hope this helps,,, Aziz,,, Update: There are also es, esh, eshell, kiss, lsh, pdksh, sash, and many more available on my Debian box.	[reply]

Or you can use the Shell module, which is part of the standard distribution of Perl. TStanley -------- There's an infinite number of monkeys outside who want to talk to us about this script for Hamlet they've worked out -- Douglas Adams/Hitchhiker's Guide to the Galaxy	[reply]
