Grep the number of occurences in a file, counting multiple hits per line

Grep prints one line per match. To return the number if matches, use the -c switch:

grep -c "something" filename

However, if a word appears more than once in a line, it is only counted once.

To count every match, you can use sed to force line breaks on multiple matches:

sed 's/something/something\n/g' filename | grep -c "something"

Once an application no longer requires constant development, it needs periodic maintenance for stable and secure operation. makandra offers monthly maintenance contracts that let you focus on your business while we make sure the lights stay on.
