Need Help??

I tried it with a : seperator, but you're right I didn't use the \t. Mea culpa.

Odd. Using \t does work (in the sense that it compiles) because `join(t, @F)` is valid Perl, and all it does is generate a warning. Using : however does not work, unless your Perl can compile `join(:, @F)`.	[reply] [d/l] [select]

Hmmph. I (foolishly) re-typed for the comment (with an eye on the original) rather than cut-and-paste my test. You're absolutely right, this is what I'd used (from my .bash_history): `export F=: perl -na -F$F -e "shift @F; print join('$F', @F);" < foo` [download] This has the problems you noted if $F is anything special to the shell (e.g. \t, contains spaces, etc). Sorry for the lack of precision in quoting. No real excuses. Will try harder.	[reply] [d/l]
