Notes:
1. "grep -q" does not need to be in [test brackets] because it is
a test in its own right
2. if you have filenames with spaces or funny characters it
serves yourself right.
3. In case you want this to be portable, keep in mind that '-i' is
a nonstandard extension. '-i' takes an argument, on my platform
at least.
The argument for "-i" is optional; if supplied sed provides a
backup; if not supplied sed amends the input file. See "man sed"
That is ridiculous. Unless you know in advance what the argument
will be, it is not possible to detect that it has not been supplied.
Anyhow, my main point is that any form of '-i' is a nonstandard
extension.
