regex - Match only first occurrence of digit -


after few hours of disappointed searching can't figure out.

i piping grep input, want first occurrence of digit.

example:

nmcli --version nmcli tool, version 1.1.93

pipe grep regex

nmcli --version |grep -o '[[:digit:]]'

output:

1 1 9 3

what want:

1

yeah there way pipe, there "pure" single regex that?

with gnu grep:

nmcli --version | grep -po ' \k[[:digit:]]'

output:

 1

see: support of \k in regex
