It's a nice feature of less, but less is a pager, so you can't pipe the result to `grep` or `sed` or `awk` or something.

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.
