From the below file I want to grep only the lines except the comment sections. But grep -v "#" is eliminating the last line because it has one # in between.
Any idea how can I ignore only the lines which have # at the begining (I mean comment lines) ?
Thanks a lot to all in advance

combinediff
COMBINEDIFF(1) COMBINEDIFF(1)
NAME
combinediff - create a cumulative unified patch from two incremental patches
SYNOPSIS
combinediff [-p n] [-U n] [-d PAT] [-Bbiqwz]
[--interpolate | --combine] diff1 diff2
combinediff {--help | --version}
DESCRIPTION
combinediff creates a unified diff that expresses the sum of two diffs. The diff files must be listed in the order that they are to be
applied. For best results, the diffs must have at least three lines of context.
The diffs may be in context format. The output, however, will be in unified format.
OPTIONS
-p n When comparing filenames, ignore the first n pathname components from both patches. (This is similar to the -p option to GNU
patch(1).)
-q Quieter output. Don't emit rationale lines at the beginning of each patch.
-U n Attempt to display n lines of context (requires at least n lines of context in both input files). (This is similar to the -U option
to GNU diff(1).)
-d pattern
Don't display any context on files that match the shell wildcard pattern. This option can be given multiple times.
Note that the interpretation of the shell wildcard pattern does not count slash characters or periods as special (in other words, no
flags are given to fnmatch). This is so that ``*/basename''-type patterns can be given without limiting the number of pathname com-
ponents.
-i Consider upper- and lower-case to be the same.
-w Ignore whitespace changes in patches.
-b Ignore changes in the amount of whitespace.
-B Ignore changes whose lines are all blank.
-z Decompress files with extensions .gz and .bz2.
--interpolate
Run as ``interdiff''. See combinediff(1) for more information about how the behaviour is altered in this mode.
--combine
Run as ``combinediff''. This is the default.
--help Display a short usage message.
--version
Display the version number of combinediff.
BUGS
The -U option is a bit erratic: it can control the amount of context displayed for files that are modified in both patches, but not for
files that only appear in one patch (which appear with the same amount of context in the output as in the input).
