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:

Copygrep -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 Show archive.org snapshot to force line breaks on multiple matches:

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