Re: Using perl interactively with VI

How about as a one-liner?

perl -pi -le'$_=substr($_,0,index($_,"?")+1)' file.txt
[download]

(update: added +1 to preserve first question mark)

No -i switch if you call perl as a filter from an editor!	[reply]

Then what about: `#!/usr/bin/perl -pi s/this/that/g;` [download] I honestly don't know how to call filters from vi ... so i don't know how to test this. But i think this should take care of the problem. UPDATE: Just figured out how to use filters in vi, that wasn't hard at all! Yes, this definetly takes care of the problem. :) jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]
