perl programs from the command line in the manner of sed?

OfficeLinebacker has asked for the wisdom of the Perl Monks concerning the following question:

Esteemed Monks,

I ended up using a bunch of sed commands to alter a file I had into a format that I ultimately used with grep -f.

I'd like to learn more about how to use perl one-liners to do the same thing. I did a SuperSearch, but can't seem to figure out how to isolate 'sed' alone from 'used','uninitialised', etc.

Any recommendations on this? Or should I just stick with sed for quickie one-liners?

Thanks,

You may wish to try s2p, the sed to perl script, to get an idea of how to translate. Also check out perlrun for a number of useful runtime switches that make creating one liners much easier. -Mark	[reply]

The Perl documentation includes perlrun, which has most of the info you'll need, but it might not be enough of a "tutorial" style to really get you started. I wrote a node a little over a year ago that worked out to be a sort of crash course in one-liners; certanly not complete, but enough to get you started. You can find it here: Re: One Liners.

You should check perldoc perlrun, in particular you're likely to be interested in `-n`, `-p`, or the "chomping versions" `-ln`, `-lp`, possibly with inline modifying, `-i` and/or with changing the input record separator... As for PM's Super Search, try with `"oneliners"` et similia, although the results won't be focused on conversions from sed, they're likely to solve tasks similar to the ones you're interested in.

Does your name rhyme with "Quasar" or "blazer?" Ok, so I see the search term I should be focusing on is oneliner and its derivatives...thanks! Also, s2p exists on my system! (seems relatively rare comapared to some of the other suggestions I've gotten, mostly re: modules). Time to "man up" on that! Thanks for treating a newbie so kindly.	[reply]
