in reply to What one-liners do people actually use?

I often find myself making use of the autosplit functionality on Windows (and even on UNIX, because I don't know much about awk).

Just last month, a cow-worker asked me for a Perl script to extract and print three specific columns from a 33-column .csv file.

perl -F, -ane "print join(',' => @F[0,8,9]), qq[\n] if (@F == 33)" inp
+ut.txt

My favorite perldoc has got to be perlrun.

I would have written that as:

perl -F, -alne '$, = ","; @F == 33 and print @F[0,8,9]' input.txt
