.TH CHPASSWD 8
.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,
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。
.SH 又见
passwd(1),useradd(8),newuser(8)
