    you could try using head and tail if your line is to be inserted in
    a fixed line number.
    For any non trivial case I would use sed (despite what Hyo Joon You
    says, ed is outdated, slow for big files, and there are platforms
    where it is not installed by default anymore).
    the idea is either:

    1) to build a file containing:
      /PATTERN/a\
      your edited line to be appended
    and doing sed -f THIS_FILE_JUST_BUILT
    (problem: the line needs to be edited to replace \ by \\)
    2) else, put the line infile FOO and do
      sed -e '/PATTERN/rfoo'

    If this doesn't suffice please give more details about your specific
    problem.
