MySQL


Code:
grep -w "echo" tst | wc -w

echo is the word you are looking for and tst is the file.

grep just reports the number of lines which match (and you should use grep -c rather than pipe to wc).

If you have grep -o then you can use that:


Code:
grep -w -o echo tst | wc -l

In your example you seem to want to count the word-internal occurrences as well; take out the -w option in that case.

Please use code tags to make your examples clearer.
