Any hints? > > awk '{print} /regexp/{print "some stuff"}' Thanks a lot. After careful consideration, my requirement should be described as follows: 1- If "some stuff" already exits immediately after the line matching regexp, do nothing. 2- If "some stuff" already exits in other locations, move it to desired location, i.e., immediately after the line matching regexp. 3- If "some stuff" doesn't exit, insert it immediately after the line matching regexp.
