.SH "描述"
.PP
The
/etc/login\&.defs
file defines the site\-specific configuration for the shadow password suite\&. This file is required\&. Absence of this file will not prevent system operation, but will probably result in undesirable operation\&.
.PP
This file is a readable text file, each line of the file describing one configuration parameter\&. The lines consist of a configuration name and value, separated by whitespace\&. Blank lines and comment lines are ignored\&. Comments are introduced with a "#" pound sign and the pound sign must be the first non\-white character of the line\&.
.PP
Parameter values may be of four types: strings, booleans, numbers, and long numbers\&. A string is comprised of any printable characters\&. A boolean should be either the value
\fIyes\fR
or
\fIno\fR\&. An undefined boolean parameter or one with a value other than these will be given a
\fIno\fR
value\&. Numbers (both regular and long) may be either decimal values, octal values (precede the value with
\fI0\fR) or hexadecimal values (precede the value with
\fI0x\fR)\&. The maximum value of the regular and long numeric parameters is machine\-dependent\&.
.PP
提供如下配置项：
.PP
\fBPASS_MAX_DAYS\fR,
\fBPASS_MIN_DAYS\fR
and
\fBPASS_WARN_AGE\fR
are only used at the time of account creation\&. Any changes to these settings won\*(Aqt affect existing accounts\&.
