There are so many times I do searches on HN to recall about some nice things I've seen oh the web... Quite often, the comments are the gems!

If you want a fast way to read the EXAMPLES section only for a command, here is a shell function which creates an ‘eg’ command which only displays the “EXAMPLES” section of manual pages:
eg(){
MAN_KEEP_FORMATTING=1 man "$@" 2>/dev/null \
| sed --quiet --expression='/^E\(\x08.\)X\(\x08.\)\?A\(\x08.\)\?M\(\x08.\)\?P\(\x08.\)\?L\(\x08.\)\?E/{:a;p;n;/^[^ ]/q;ba}' \
| ${MANPAGER:-${PAGER:-pager -s}}
}
$ eg tar
EXAMPLES
Create archive.tar from files foo and bar.
tar -cf archive.tar foo bar
List all files in archive.tar verbosely.
tar -tvf archive.tar
Extract all files from archive.tar.
tar -xf archive.tar
$It also has a terminal client called "fu": https://github.com/samirahmed/fu
$ bro curl
The curl command isn't in our database.A different (but related) resource: http://explainshell.com - good for deciphering those tricker commands.
It was posted elsewhere in this thread first — https://news.ycombinator.com/item?id=10023535 — so don't vote my comment up.
Is this due to an LB fronting?
You probably meant lower :)
