The encrypted password field may be blank, in which case no password is required to authenticate as the specified login name. However, some applications which read the
|
|
\fI/etc/passwd\fR
|
|
file may decide not to permit
|
|
\fIany\fR
|
|
access at all if the
|
|
\fIpassword\fR
|
|
field is blank. If the
|
|
\fIpassword\fR
|
|
field is a lower\-case
|
|
\(lqx\(rq, then the encrypted password is actually stored in the
|
|
\fBshadow\fR(5)
|
|
file instead; there
|
|
\fImust\fR
|
|
be a corresponding line in the
|
|
\fI/etc/shadow\fR
|
|
file, or else the user account is invalid. If the
|
|
\fIpassword\fR
|
|
field is any other string, then it will be treated as an encrypted password, as specified by
|
|
\fBcrypt\fR(3).
|
|
.PP
|
|
The comment field is used by various system utilities, such as
|
|
\fBfinger\fR(1).
|
|
.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$HOME\fR
|
|
environmental variable.
|
|
.PP
|
|
The command interpreter field provides the name of the user's command language interpreter, or the name of the initial program to execute. The
|
|
\fBlogin\fR
|
|
program uses this information to set the value of the
|
|
\fB$SHELL\fR
|
|
environmental variable. If this field is empty, it defaults to the value
|
|
\fI/bin/sh\fR.
