.SH NAME 名字
 | 
						||
chpasswd \- 成批更新用户的口令
 | 
						||
.SH 总览
 | 
						||
chpasswd [\-e]
 | 
						||
.SH 描述
 | 
						||
.B chpasswd
 | 
						||
从系统的标准输入读入用户的名称和口令,
 | 
						||
并利用这些信息来更新系统上已存在的用户的口令。
 | 
						||
在没有用 \-e 这个开关选项的情况下,口令将按明文的形式接收。
 | 
						||
如果使用了 \-e 选项,口令将只能以加密的方式传递。
 | 
						||
每行的具体格式如下所示:
 | 
						||
.sp 1
 | 
						||
		\fI用户名\fR:\fI新口令\fR
 | 
						||
.sp 1
 | 
						||
用户名必须是系统上已存在的用户。
 | 
						||
输入的密码在必要时进行加密处理,
 | 
						||
如果口令文件具有时间特性,则同时更新。
 | 
						||
.PP
 | 
						||
此命令适用于大型的系统,在此类系统中,
 | 
						||
用户一般都是一次同时生成的,而用 adduser 和
 | 
						||
passwd 口令来对其一一进行设置一般说往往比较慢。
 | 
						||
.SH 注意事项
 | 
						||
.\" The \fBmkpasswd\fR command must be executed afterwards to update the
 | 
						||
.\" DBM password files.
 | 
						||
.\" This command may be discarded in favor of the newusers(8) command.
 | 
						||
因为可以使用文件重定向进行输入,
 | 
						||
即:chpasswd < user&passwd\-filename, 
 | 
						||
如果输入文件是按非加密方式传递的话,请对该文件进行适当的加密。
 | 
						||

 |
