Find every word with grep beginning with /dev/, containing any character after that until a space

Question

Let's say the input is something like this:

/dev/sda1 something something word word /dev/sda4/ something word word

I want to achieve this output using grep:

/dev/sda1 /dev/sda4

I currently have this: grep -o "\/dev\/", but it only prints /dev/, and not the rest of the word.

You can match characters that aren't in a given set of characters like this:

grep -o "/dev/[^ ]*"

(Edited to remove the unnecessary backslashes.)

Do not use `\/`, use `/`. `grep` patterns do not use regex delimiters. – Wiktor Stribiżew May 06 '18 at 15:03
Thanks, I didn't even see that those were in there. – snowcat May 06 '18 at 15:05
