Answer by steeldriver for How to find multiple files with specific pattern using or in find command

You can use

! \( -name '.bashrc' -o -name '.profile' \)

Ex.

$ find /etc/skel ! \( -name '.bashrc' -o -name '.profile' \)
/etc/skel
/etc/skel/.mkshrc
/etc/skel/examples.desktop
/etc/skel/.kshrc
/etc/skel/.bash_logout

The quotes aren't actually necessary in this case but you should get in the habit of using them in the case that the search pattern contains glob characters.
