Re: sed, grep question

["Mark Thompson" <mthompson ed umuc edu>]

	My first suggestion would be RTFM(I normally hate this answer, but you really
should look at man pages as they are normally full of really good info).

	You can use grep.  The command would look like this:

grep -v "^#" filename > output-file

grep -v outputs all non-matching lines from filename into a file called
output-file.  The above grep outputs all lines not containing # as the first
character of the line.  The output is then redirected to a file.  You can then
rename the output-file to whatever you like.
