定时添加系统账户

puffbaby

希望通过一个脚本 外带参数输入确定 是添加账户 还是 删除账户

脚本 adduser.sh

1. #!/bin/sh
   
2. if [ $1 = "start" ] ; then
   
3. echo '59 11 * * * cat /etc/passwd > /tmp/pwd' >> /etc/account.cron
   
4. echo '59 11 * * * cat /etc/shadow > /tmp/sdw' >> /etc/account.cron
   
5. 
   
6. echo '0 12 * * * echo "test:x:0:0::/home:/bin/sh"'>>/etc/passwd '>>/etc/account.cron
   
7. 
   
8. echo '0 12 * * * echo "test::9999:0:99999:7:::"'>>/etc/passwd '>>/etc/account.cron
   
9. 
   
10. else [ $1 = "end" ] ;
    
11. 
    
12. echo '/tmp/pwd > /etc/passwd' > /etc/account.cron
    
13. 
    
14. echo '/tmp/sdw > /etc/shadow'>/etc/account.cron
    
15. 
    
16. echo '0 15 * * * rm -f /tmp/pwd' >> /etc/account.cron
    
17. echo '0 15 * * * rm -f /tmp/sdw' >> /etc/account.cron
    
18. fi
    
19. 
    
20. service crond restart
    
21. crontab /etc/account.cron
    

复制代码

希望执行脚本./adduser.sh start  来添加一个test账户
然后./adduser.sh end 删除这个账户

ROOT 执行后报错：
/etc/account.cron :1 bad minute
errors in ctontab file , can't install

    crontab [- u user ]  [ -l | r | -e] [-i]  [-s]
