案例-接着上一个案例
希望批量删除上个案例创建的所有用户
脚本展示：（下次再解释）
#!/bin/bash echo > userlist.txt; for i in `seq 50` do id student$i >/dev/null 2>/dev/null; [ $? -ne 0 ] && echo -e "[\033[31merror\033[0m] user student$i not exist." && continue; userdel -r student$i >/dev/null 2>/dev/null; [ $? -eq 0 ] && echo -e "[\033[32mok\033[0m] delete user student$i succes." done
脚本运行
[root@arppinging scripts]# bash rmuser.sh [ok] delete user student1 succes. [ok] delete user student2 succes. [ok] delete user student3 succes. [ok] delete user student4 succes. [ok] delete user student5 succes. [ok] delete user student6 succes. [ok] delete user student7 succes. [ok] delete user student8 succes. [ok] delete user student9 succes.
