PASSWD(5)

NAME
passwd - The password file

DESCRIPTION
/etc/passwd contains various pieces of information for each user account. Included is:

    Login name

    Optional encrypted password

    Numerical user ID

    Numerical group ID

    User name or comment field

    User home directory

    User command interpreter

The password field may not be filled if shadow passwords have been enabled. If shadow passwords are being used, the encrypted password will be found in /etc/shadow. The encryped password consists of 13 characters from the 64 character alphabet a thru z, A thru Z, 0 thru 9, . and /. Refer to crypt(3) for details on how this string is interpreted.

The comment field is used by various system utilities, such as finger(1). Three additional values may be present in the comment field. They are:

    pri= - set initial value of nice

    umask= - set initial value of umask

    ulimit= - set initial value of ulimit

These fields are separated from each other and from any other comment field by a comma.

The home directory field provides the name of the initial working directory. Login uses this information to set the value of the HOME environmental variable.

The command interpreter field provides the name of the user's command language interpreter, or the name of the initial program to execute. Login uses this information to set the value of the SHELL environmental variable. If this field is empty, it defaults to the value /bin/sh.
