Many great responses

Thanks to all:

Original question:

I seem to remember a version of grep that would give you the matching line
plus a specified number of lines before and after.

Drawing a blank as to where I have seen this though.

Any Ideas?

TIA
<mike>

Answers:

GNU grep has -B (before) & -A (after) to specify the number of extra lines
you want to include.

GNU grep supports the option "-C linesbefore,linesafter"

Others responded with grep -n, but that only gives the line number.

Thanks to all especially GNU
