Trying to avoid a perl script which wouldn't be hard, but I am looking for an awk one liner that does a replacement, but only after it sees a key word on some line.
Anyone know of that's easy to do?
Depends on how you define "one-liner." Something like this might work:
{ if index($0, PATTERN) != 0 {FOUND = 1;}; if (FOUND != 0) {subst(REPLACE_THIS, WITH_THIS, $0); }
You'd want to reverse the order of the two statements if the replacement is only to occur after the pattern is found.
Now, if you want to process multiple files, you'd have to reset the found flag when the filename changes, and that's another if-else clause, which gets kind of long for a "one liner."
It's ugly, but it's awk....
