How to perform chown and chgrp in one command

Question

In order to change both a file's owner and group we can do this:

chown trump file
chgrp trump file

but can I do both commands in one approach or one command?

POSIX specifies allowed characters for user and group names. (pubs.opengroup.org/onlinepubs/9699919799/basedefs/…) The BSD chown manual states "Previous versions of the chown utility used the dot (.) character to distinguish the group name. This has been changed to be a colon (:) character, so that user and group names may contain the dot character." The RHEL man page for chown does not have that usage note. Nonetheless, there are reasons to abstain from using the . character.

Be careful what username: and :groupname are not standards - see unix.stackexchange.com/a/136989/383045
