8月1日作业
创建testuser uid 1234,主组：bin,辅助组：root,ftp,shell:/bin/csh home:/testdir/testuser
[root@localhost ~]# useradd -u 1234 -g bin -G root,ftp -s /bin/csh -d /testdir/testuser testuser [root@localhost ~]# tail -1 /etc/passwd testuser:x:1234:1::/testdir/testuser:/bin/csh [root@localhost ~]# id testuser uid=1234(testuser) gid=1(bin) groups=1(bin),0(root),50(ftp)
2.修改testuser uid:4321,主组：root,辅助组nobody,loginname:test，home:/home/test 家数据迁移
[root@localhost ~]# usermod -u 4321 -g 0 -G 99 -md /home/test -l test testuser [root@localhost ~]# id test uid=4321(test) gid=0(root) groups=0(root),99(nobody) [root@localhost ~]# tail -1 /etc/passwd test:x:4321:0::/home/test:/bin/csh
3.批量创建帐号：user1…user10 uid:3000-3009,shell:/bin/csh,home:/testdir/username passwd:usernamepass 注意家目录相关配置，使用户正常登录 此题因为用户太多，因此最后显示了一个用户成功，即为实验成功。
