Re^2: In place edit and printf

Your solution has two problems:

1) Injection Vulnerability

You don't escape the %s in $1 and $'. Pass them as arguments to printf instead, adding %s in the format string where necessary

2) Performance Leak

Using $' can cause other (unrelated) regexp in your program to slow down. Add (.*) to the end of the regexp and use $2 instead of $'.

You would think with all the recent noise about the printf bug I would have remembered that. I was too focused on the initial question at hand. Ted Young `($$<<$$=>$$<=>$$<=$$>>$$) always returns 1. :-)`	[reply] [d/l]
