What is your intent with using grep -o? My bash is telling me that's not a valid option.

The -o flag tells grep thet it needs to return only the matched section:

(clockwork) Ξ ~ → echo -en "Number: 123141221\nNot number: ajhdkjasd\n"
Number: 123141221
Not number: ajhdkjasd
(clockwork) Ξ ~ → echo -en "Number: 123141221\nNot number: ajhdkjasd\n" | grep "[0-9]\+"
Number: 123141221
(clockwork) Ξ ~ → echo -en "Number: 123141221\nNot number: ajhdkjasd\n" | grep -o "[0-9]\+"
123141221
(clockwork) Ξ ~ →

Section from the man: unixhelp.ed.ac.uk

-o, --only-matching
   Prints only the matching part of the lines.

I dont see your answer only I got a mail about it. Same issue with npm on windows. https://github.com/creationix/nvm/issues/75. There is a comment that says:

Since this is one of the first google results for git bash's seemingly terribly outdated grep problem, I'll post a temporary workaround here.
Open <Git install directory>/bin and overwrite grep.exe with a more up to date version. I found two alternatives that provide -o support: GnuWin32's grep 2.5.4

Sorry, I deleted it as after posting I found that exact download. Now, though, sed seems to be doing nothing...

I don't have a Windows box so I can't test or figure out what would be the problem. If you find please tell us. If someone meets the same problem then (s)he can find the solution here :)

Maybe. Try to do not escape the ? and parentheses. Just a guess and maybe it works :)

Yeah, I had to add -r as the first flag to sed and then treat the pattern like normal regex - as in, only escape characters you want as literals. So it now looks like this:

curl -s https://www.youtube.com/results\?search_query\=$3 | \
        grep -o 'watch?v=[^"]*"[^>]*title="[^"]*' | \
        sed -r -e 's/^watch\?v=([^"]*)".*title="(.*)/\1 \2/g'

You still have to escape the ? because it's a text character you want to match, you don't want it to be evaluated as a regex operator.

I hope you don't mind, but I've done a bit of work expanding on the code you've posted here. Of course, I've attributed you as the original author.

I turned it into a shell script for easier development, and I've combined the search output and URL generation under -s and -w flags. My intention is to make it so you can do a search, then pick a video and even specify how to handle launching the video.

So far I've only tested on Windows using Git Bash, but here's what I've got:

Nice :D (if someone asks me next time about Windows bash I will know the answer).

The script is awesome. My first usage was a script with readline and after the search the user (aka me) could select with a simple numeric answer to what to do. I use it for a while but after that I made a few small command instead of big script. It's more comfortable for me now :)
