Default passwd File
The default passwd file contains entries for standard daemons. Daemons
are processes that are usually started at boot time to perform some system-wide task, such as
printing, network administration, or port monitoring.
The following display shows the contents of a sample passwd file.
Note -
Additional users and groups are created and removed when packages are added or removed from
the system. These ongoing changes are reflected in the passwd file.
Administrators should not need to clean up this file.
