The following was found using: grep (GNU grep) 2.4.2
Hi,
using the great GNU grep tool and preparing some general documentation to
be published to help Linux users use their onboard information sources
I just found a little bug in both the 'grep' manpage and the 'grep' info:
-C [NUM], -NUM, --context[=NUM]
Print NUM lines (default 2) of output context.
This is wrong.
While me calling "grep -A 3 sometext somefile" works fine
and calling "grep -A3 sometext somefile" works fine
and calling "grep -B 3 sometext somefile" works fine
and calling "grep -B3 sometext somefile" works fine
the following
does *not* work: "grep -C 3 sometext somefile" works fine
but this WORKS: "grep -C3 sometext somefile" works fine
So the manpage and info text should say:
-C[NUM], -NUM, --context[=NUM]
Print NUM lines (default 2) of output context.
Removing the space between "-C" and "[NUM]" removes the bug. :-)
