If you create a man page
Please add a comma to your short options (-o, --option). This makes it easier to look it up.
Just something i wanted Linuxers to be aware of.

Seems to work, albeit you'll hit later mentions doing it more than once, but yeah word boundary searches are awesome.
Agree with your overall suggestion, just a tip for when the man page doesnt cooperate.
I believe you but in the spirit of regex, can you explain?
I guess hyphen is literal outside of square brackets. But then you’re escaping an angle bracket?
Also curious what trouble OP was having. Wouldn’t a trailing space be enough?
‘/-o ‘
The problem is that
/-owill also match something like--my-irrelevant-option.Word boundaries match the end (or the beginning) of the word.
How exactly to do it depends on the regex library, my
lessis built withPCRE2therefore I can do/-o\b.Dealing with multiple more complex tools the last few days, looking the short option up, because i needed to know what it does, was about a hundred steps through walls of text. Then came the yay and curl manpages; one or two steps. That's when i wrote the post.
It depends on how the document is written, but \> stops matching on a period, comma, apostrophe, space, newline, what have you. Word boundary matching is just very handy.
As to why its that set of characters.... Honestly I have no idea :) Regexes are just what they are and I assume the special escape made sense to the inventor at least.
I feel like this should go to some of the programming communities also, but I’m not a programmer so I don’t know where
Very interesting idea. I’ve gotten into the habit of using something like
/^-oto search for short flags.I've been using more https://cheat.sh/ or
--helpon specific commands and subcommands.It's usually less noise than in a man page, and no need to install a specific man page for each command you want.
