do you mean the count of matching lines? If so, then -c option will do it. From man page on a NetBSD system:

Code:
-c, --count
              Suppress  normal output; instead print a count of matching lines
              for each input file.  With the -v,  --invert-match  option  (see
              below), count non-matching lines.

Code:
~ grep --version
grep (GNU grep) 2.5.1a nb1

show-installed [options] DESCRIPTION
show-installed gives a compact description of the packages installed (or given) making use of the comps groups found in the repositories. OPTIONS
-h, --help show this help message and exit -f FORMAT, --format=FORMAT yum, kickstart or human; yum gives the result as a yum command line; kickstart the content of a %packages section; "human" readable is default. -i INPUT, --input=INPUT File to read the package list from instead of using the rpmdb. - for stdin. The file must contain package names only separated by white space (including newlines). rpm -qa --qf='%{name} ' produces proper output. -o OUTPUT, --output=OUTPUT File to write the result to.

Those groups are commented out with a "# " at the begin of the line. -m, --allow-mandatories Check if just installing the mandatory packages gives better results. Uses "." to mark those groups. -a, --allow-all Check if installing all packages in the groups gives better results. Uses "*" to mark those groups. --ignore-missing Ignore packages missing in the repos. --ignore-missing-excludes Do not produce exclude lines for packages not in the repository.
