案例需求
用shell脚本批量建立Linux用户
实现要求:创建用户student1到student50,指定组为student组!而且每个用户需要设定一个不同的密码!

实现脚本

#!/bin/bash
grep ‘student‘ /etc/group >/dev/null 2>/dev/null
[ $? -eq 0 ] || groupadd student >/dev/null 2>/dev/null

for i in `seq 50`
do
   id student$i >/dev/null 2>/dev/null; 
  [ $? -eq 0 ] && echo -e "[\033[31merror\033[0m]User student$i is exist." && continue;
  useradd -G student student$i >/dev/null 2>/dev/null;
  pass=`echo "$RANDOM$RANDOM"`;
  [ $? -eq 0 ] && echo -e "[\033[32mok\033[0m]user student$i create success." && echo "$pass" | passwd student$i --stdin >/dev/null 2>/dev/null;
  [ $? -eq 0 ] && echo "student$i  $pass" >> userlist.txt

done
