Change root password on GNU/Linux

$ sudo passwd root

will prompt you to type a new password, twice.

You can always use apropos to look for utilities. For example, if you are seeking to change the root password, you can run:

$ apropos -a change password

which will print:

chage (1)            - change user password expiry information
passwd (1)           - change user password
smbpasswd (8)        - change a user's SMB password

Then run $ man passwd to read how it works i.e. the description.
