Question bash : crop some text with regex

I'm new to bash scripting
it seems very powerful so I'm learning

I would like to crop all the xxx-xx from a text file
I tried

TR=" `grep -e "[0-9][0-9][0-9]-[0-9][0-9]" ~/index.html`"
but grep output the full lines
I just want xxx-xx

I also tried with sed, but I could only replace what I wanted to get...

thanks for any help

I think you mean you want to select xxx-xx from a text file.

See the manpages for grep(1). You most likely want the -o option.
