If you are not interested in seeing all the qualifying lines, but you just want to know which files have at least one occurrence of the grep string, then use grep -l option: grep -l xyz *

Apalex you can pass a parameter to awk whith the FLAG -v

awk -v seek_word=<word> 'BEGIN{ ..<your_code>...}END{..<your_code>... }' file

or similar syntax see man awk. Jimbo thanks with Natty.

to compare the perfomance use the time command.
