in reply to Grepping surrounding lines, is this redundant?

That this doesn't already exist as a standard UNIX tool ( I figure there must be).

GNU grep

grep -3
  -C [NUM], -NUM, --context[=NUM]
  Print NUM lines (default 2) of 
  output context.

grep -A3
  -A NUM, --after-context=NUM
  Print NUM lines of trailing context 
  after matching lines.

grep -B3
  -B NUM, --before-context=NUM
  Print NUM lines of leading context 
  before matching lines.

Update:
If by the incredible chance it doesn't, should I submit it as a patch?

Submit a patch regardless. :-)

    Thanks.
    Duh! I can't believe I never saw that. I knew it had to be long done already. I did do some googling put apparently I wasn't looking for the right terms. Oh well. I will polish it regardless as I do like the way I have the numbering set up. (It can number the lines -N - 0 (match)- N+ which I happen to like)
