Re: Grepping surrounding lines, is this redundant?

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

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) ############################## -5: -4:use 5.006; -3:use strict; -2:use warnings; -1: 0:use constant PREFIX => '_Branch_'; 1: 2:use HTML::Parser; 3:use HTML::Tagset; 4:use Data::Dumper; 5: ############################## -Lee "To be civilized is to deny one's nature."
