批量创建用户账号和自定义回收站

Posted 2020-10-15

1、批量创建(zhangsan lisi wangwu)账号

[[email protected] ~]# vim f2

[[email protected] ~]# cat f2

zhangsan:x:560:560::/home/zhangsan:/bin/bash  ----/tec/passwd格式

lisi:x:550:550::/home/lisi:/bin/bash

wangwu:x:555:555::/home/wangwu:/bin/bash

[[email protected] ~]# newusers f2

[[email protected] ~]# getent passwd | tail -n3

zhangsan:x:560:560::/home/zhangsan:/bin/bash

lisi:x:550:550::/home/lisi:/bin/bash

wangwu:x:555:555::/home/wangwu:/bin/bash

[[email protected] ~]# ll /home

total 16

drwx------. 2    622    622 4096 Jul 24 11:09 lisi

drwx------. 2 wangwu wangwu 4096 Jul 24 11:18 wangwu

drwx------. 2    522    522 4096 Jul 24 11:09 zhangsan

[[email protected] ~]# ls -a /home/wangwu

.  ..                                                           ----  无/etc/skel配置文件 需手动在home/wangwu配置skel下文件

wangwu为例：

[[email protected] ~]# id wangwu

uid=555(wangwu) gid=555(wangwu) groups=555(wangwu)

[[email protected] home]# cp -a /etc/skel/.[^.]* wangwu              如果家目录不存在[[email protected] home]# cp -r /etc/skel wangwu

[[email protected] home]# ll -a wangwu                                          或者mkdir -m 755 wang 创建并指明文件属性

drwx------. 5 wangwu wangwu 4096 Jul 24 11:41 .

drwxr-xr-x. 6 root   root   4096 Jul 24 11:18 ..

drwxr-xr-x. 4 root   root   4096 Jul 24 11:37 skel

[[email protected] home]# chown -R wangwu:wangwu wangwu   ----修改wangwu权限属性

[[email protected] home]# ll -a wangwu

total 32

drwx------. 5 wangwu wangwu 4096 Jul 24 11:41 .

drwxr-xr-x. 6 root   root   4096 Jul 24 11:18 ..

-rw-r--r--. 1 wangwu wangwu   18 Mar 23 08:15 .bash_logout

-rw-r--r--. 1 wangwu wangwu  176 Mar 23 08:15 .bash_profile

-rw-r--r--. 1 wangwu wangwu  124 Mar 23 08:15 .bashrc

drwxr-xr-x. 2 wangwu wangwu 4096 Nov 12  2010 .gnome2

drwxr-xr-x. 4 wangwu wangwu 4096 Jul 11 21:49 .mozilla

drwxr-xr-x. 4 wangwu wangwu 4096 Jul 24 11:37 skel

：如果一主机账户往另一主机迁移，可以用getent /etc/passwd username>f1 用scp命令将f1传入另一主机 ，执行newusers f1 并将/etc/skel下文件复制到各自home下的家目录下

2、批量修改密码

[[email protected] home]# cat /etc/shadow |tail -3

[[email protected] home]# getent shadow|tail -3

zhangsan:$6$E6B60/L4QLm/$QRvHhvzO913b9lKiAB.eS0Xnc0pRiIKGrj6Qb9PTCR0ewZToEigR2SnymXGzx0s3DK.CpnYeQsOGGEPsj4sZD0:17371:0:99999:7:::

lisi:$6$5EXlM/T9JmK/sD$rAuvVydrapeWcSNMi3MCk.X7S3PUUG5OmiU1PxFYbuYB2l4LPvhXcaS0dFfHkLBHkoNIKzq4Yx48VeMlaOJo8/:17371:0:99999:7:::

wangwu:$6$vZ42Ltw2V$pbrHI27HeUNcQDZqBCKjzDoassIapo.Q7cq0m.SshelO8AR1xwSmFAlnyV9I3uGxy.u3/s71Betm.jRo3ysVl0:17371:0:99999:7::

[[email protected] home]# vim f4

[[email protected] home]# cat f4  ----/etc/shadow格式

zhangsan:qwe123:

lisi:qwe111:

wangwu:qwe222:

[[email protected] home]# cat f4|chpasswd

[[email protected] home]# getent shadow|tail -3

zhangsan:$6$E6B60/L4QLm/$QRvHhvzO913b9lKiAB.eS0Xnc0pRiIKGrj6Qb9PTCR0ewZToEigR2SnymXGzx0s3DK.CpnYeQsOGGEPsj4sZD0:17371:0:99999:7:::

lisi:$6$5EXlM/T9JmK/sD$rAuvVydrapeWcSNMi3MCk.X7S3PUUG5OmiU1PxFYbuYB2l4LPvhXcaS0dFfHkLBHkoNIKzq4Yx48VeMlaOJo8/:17371:0:99999:7:::

wangwu:$6$vZ42Ltw2V$pbrHI27HeUNcQDZqBCKjzDoassIapo.Q7cq0m.SshelO8AR1xwSmFAlnyV9I3uGxy.u3/s71Betm.jRo3ysVl0:17371:0:99999:7:::

3、对rm命令定义回收站

避免误删除对rm进行别名定义

[[email protected] home]# alias rm='mv -t /app'   ----mv [OPTION]... -t DIRECTORY SOURCE...

[[email protected] home]# touch f5

[[email protected] home]# rm f5

[[email protected] home]# ls /app

f5  lost+found

总结：mv命令加上-t选项，使源文件放在后面，移动到前面的目录内。
