How to create a UUID in bash?

Answer 1

macOS has a built-in command line tool called uuidgen for generating UUID strings.

$ /usr/bin/uuidgen

Answer 2

After a brief search, found this http://www.ossp.org/pkg/lib/uuid/

$ brew install ossp-uuid
$ which uuid
/opt/homebrew/bin/uuid
$ ls -al /opt/homebrew/bin/uuid
/opt/homebrew/bin/uuid -> ../Cellar/ossp-uuid/1.6.2_2/bin/uuid
$ uuid
