I would like to say 10 lines max from grep.
I don’t want my computer to work hard. I want it to stop after 10 results found by grep. Is it possible?
-m option is probably what you’re looking for:
grep -m 10 PATTERN [FILE]
-m NUM, --max-count=NUM Stop reading a file after NUM matching lines. If the input is standard input from a regular file, and NUM matching lines are output, grep ensures that the standard input is positioned to just after the last matching line before exiting, regardless of the presence of trailing context lines. This enables a calling process to resume a search.
Note: grep stops reading the file once the specified number of matches have been found!
