The -m option only works with grep on Linux (it is a GNU grep feature).

Code:
grep -m 5 'pattern' myfile

This finds pattern and after the fifth time it has printed the line containing pattern it stops the search.

read the man page on your system.

Code:
grep -m NUM pattern file

Stop the search for the pattern after NUM matching lines. For more details, refer to man pages.
