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....
