超大批量一次性完成用户创建，并指定密码
各位Postmasterw你们好，Qmail+Vpopmail+sqwebmail+mysql.....几乎是webmail的主流。很少人用/etc/passwd验证用户，所以系统中的用户很少，管理起来也方便。但是Qmail+Vpopmail+sqwebmail+mysql.....这套系统能做出来的人。哼恐怕没几个人做成吧？
所以好多系统管理员不得不用Sendmail+/etc/passwd验证mail用户，用户随时间而增加，到了50个用户时恐怕.....；
公司为了省钱一台服务器上装一大堆东东，如果万一那一天出了事。那么你的邮件用户就全完蛋 :（ 。然后是重做系统，一个一个的建用户加改密码.....，至少搞上一天，公司收不到邮件，你还要被老板K
程序：
[root@linux netkiller]# cat mailuser
#!/bin/sh
MAILUSERLIST=mailuserlist
gawk '{print "/usr/sbin/adduser "$1" -s /usr/bin/passwd"}' $MAILUSERLIST > addmailuser
gawk '{print $1":123"}' $MAILUSERLIST > mailuserpasswd
chmod 755 addmailuser
./addmailuser
cat mailuserpasswd | /usr/sbin/chpasswd
rm -rf addmailuser mailuserpasswd
[root@linux netkiller]# cat mailuserlist
user1
user2
user3
脚本写的不好。
[root@linux_10 root]# man chpasswd

NAME
chpasswd - update password file in batch
SYNOPSIS
chpasswd [-e]
DESCRIPTION
chpasswd reads a file of user name and password pairs from standard input and uses this information to
update a group of existing users. Without the -e switch, the passwords are expected to be cleartext. With
the -e switch, the passwords are expected to be in encrypted form. Each line is of the format
user_name:password
The named user must exist. The supplied password will be encrypted as necessary, and the password age
updated, if present.
This command is intended to be used in a large system environment where many accounts are created at a
single time.
CAVEATS
The input file must be protected if it contains unencrypted passwords.
