passwd - The password file
!!DESCRIPTION


''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__.
