創建testuser uid 1234,主組：bin,輔助組：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,主組：root,輔助組nobody,loginname:test，home:/home/test 家數據遷移
[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.批量創建帳號：user1…user10 uid:3000-3009,shell:/bin/csh,home:/testdir/username passwd:usernamepass 注意家目錄相關配置，使用戶正常登錄 此題因為用戶太多，因此最后顯示了一個用戶成功，即為實驗成功。
