批量增加用户
Linux AS4下测试例子：
#cat namelistfile
aa
bb
-bash-3.00[lg]# ./adduser.sh -f namelistfile
Reading usernamelist file(namelistfile) ...
namelistfile
Now Let's set some options or you can use default settings.
Would you like to add a new group to add these users to it?
Enter (yes)to create a new group otherwise you must verify the group.
Your Answer: yes
Please enter the group's name: aa
All these users will be added to group(aa)...
Adding group ...
The group(aa) is added!
The passwd is used by default 000000.
The user(aa) is added.
Changing password for user aa.
passwd: all authentication tokens updated successfully.
The user(aa)'s password is setted!
The passwd is used by default 000000.
The user(bb) is added.
Changing password for user bb.
passwd: all authentication tokens updated successfully.
The user(bb)'s password is setted!
