I'd wager that 90% of the time that I'm using 'tail -F' I'm also piping it to grep.
This. I use:
tail -f /var/log/x.log | grep foo -A 20 -B 20
Most of the time.
You know you can also do -C 40 for 40 lines of context instead of -A 20 -B 20
Note that -C is in each direction, not total; -C20 is equivalent to -A20 -B20.
Thank you,
This is the reason I always share how I do it in hn! LOL
While you may not be able to do transforms on the output via `sed` or `awk`, you can get a grep-like filtering by using the `&` character with `less` open.
