There are so many ways to achieve that. Change the pattern in the regular expression to match only those lines you want. Make the substitution conditional on your pattern beforehand: `/pat/ and s///` Don't munge any lines which don't match: `next unless /pat/` Pick one and implement it. 🦛	[reply] [d/l] [select]
