<title>DESCRIPTION</title>
<para>
<filename>/etc/passwd</filename> contains various pieces of
information for each user account. Included is:
</para>
<para>Login name</para>
<para>Optional encrypted password</para>
<para>Numerical user ID</para>
<para>Numerical group ID</para>
<para>User name or comment field</para>
<para>User home directory</para>
<para>User command interpreter</para>
<para>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 <filename>/etc/shadow</filename>. The encrypted
password consists of characters from the 64 characters alphabet a thru
z, A thru Z, 0 thru 9, \. and /. Optionally it can start with a "$"
character. This means the encrypted password was generated using
another (not DES) algorithm. For example if it starts with "$1$" it
means the MD5-based algorithm was used.
</para>
<para> Refer to <citerefentry>
<refentrytitle>crypt</refentrytitle><manvolnum>3</manvolnum>
</citerefentry> for details on how this string is interpreted.
</para>
<para>The comment field is used by various system utilities, such as
<citerefentry>
<refentrytitle>finger</refentrytitle><manvolnum>1</manvolnum>
</citerefentry>. Three additional values may be present in the comment
field. They are:
</para>
<para>pri= - set initial value of nice</para>
<para>umask= - set initial value of umask</para>
<para>ulimit= - set initial value of ulimit</para>
<para>These fields are separated from each other and from any other
comment field by a comma.
</para>
<para>The home directory field provides the name of the initial working
directory. <emphasis remap='B'>Login</emphasis> uses this information
to set the value of the <envar>$HOME</envar> environmental variable.
</para>
<para>The command interpreter field provides the name of the user's
command language interpreter, or the name of the initial program to
execute. <emphasis remap='B'>Login</emphasis> uses this information
to set the value of the <envar>$SHELL</envar> environmental variable.
If this field is empty, it defaults to the value
<filename>/bin/sh</filename>.
