If the
\fIpassword\fR
field is a lower\-case
\(Fo\ \&x\ \&\(Fc, then the encrypted password is actually stored in the
\fBshadow\fR(5)
file instead; there
\fImust\fR
be a corresponding line in the
/etc/shadow
file, or else the user account is invalid\&.
.PP
The encrypted
\fIpassword\fR
field may be empty, in which case no password is required to authenticate as the specified login name\&. However, some applications which read the
/etc/passwd
file may decide not to permit
\fIany\fR
access at all if the
\fIpassword\fR
field is blank\&.
.PP
A
\fIpassword\fR
field which starts with an exclamation mark means that the password is locked\&. The remaining characters on the line represent the
\fIpassword\fR
field before the password was locked\&.
.PP
Refer to
\fBcrypt\fR(3)
for details on how this string is interpreted\&.
.PP
If the password field contains some string that is not a valid result of
\fBcrypt\fR(3), for instance ! or *, the user will not be able to use a unix password to log in (but the user may log in the system by other means)\&.
.PP
The comment field, also known as the gecos field, is used by various system utilities, such as
\fBfinger\fR(1)\&. The use of an ampersand here will be replaced by the capitalised login name when the field is used or displayed by such system utilities\&.
.PP
The home directory field provides the name of the initial working directory\&. The
\fBlogin\fR
program uses this information to set the value of the
\fB$HOME\fR
environmental variable\&.
.PP
The command interpreter field provides the name of the user\*(Aqs command language interpreter, or the name of the initial program to execute\&. The
\fBlogin\fR
program uses this information to set the value of the
\fB$SHELL\fR
environmental variable\&. If this field is empty, it defaults to the value
/bin/sh\&.
