2、开始安装

1. [root@VM_54_118_centos trash-cli]# python setup.py install
2. .......
3. running install_scripts
4. copying build/scripts-2.7/trash-rm -> /usr/bin
5. copying build/scripts-2.7/trash-list -> /usr/bin
6. copying build/scripts-2.7/trash-put -> /usr/bin
7. copying build/scripts-2.7/trash-empty -> /usr/bin
8. copying build/scripts-2.7/trash -> /usr/bin
9. copying build/scripts-2.7/trash-restore -> /usr/bin
10. changing mode of /usr/bin/trash-rm to 755
11. changing mode of /usr/bin/trash-list to 755
12. changing mode of /usr/bin/trash-put to 755
13. changing mode of /usr/bin/trash-empty to 755
14. changing mode of /usr/bin/trash to 755
15. changing mode of /usr/bin/trash-restore to 755
16. running install_data
17. copying man/man1/trash-empty.1 -> /usr/share/man/man1
18. copying man/man1/trash-list.1 -> /usr/share/man/man1
19. copying man/man1/trash-restore.1 -> /usr/share/man/man1
20. copying man/man1/trash-put.1 -> /usr/share/man/man1
21. copying man/man1/trash-rm.1 -> /usr/share/man/man1
22. running install_egg_info
23. Writing /usr/lib/python2.7/site-packages/trash_cli-0.17.1.14-py2.7.egg-info

3、安装成功后我们的系统就有了以下工具.

1. [root@VM_54_118_centos ~]# ll /usr/bin/ | grep trash
2. -rwxr-xr-x 1 root root 123 Feb 2 17:43 trash
3. -rwxr-xr-x 1 root root 125 Feb 2 17:43 trash-empty
4. -rwxr-xr-x 1 root root 124 Feb 2 17:43 trash-list
5. -rwxr-xr-x 1 root root 123 Feb 2 17:43 trash-put
6. -rwxr-xr-x 1 root root 127 Feb 2 17:43 trash-restore
7. -rwxr-xr-x 1 root root 122 Feb 2 17:43 trash-rm

功能说明：

trash-put 将文件或目录移入回收站
trash-empty 清空回收站
trash-list 列出回收站中的文件
trash-restore还原回收站中的文件
trash-rm 删除回首站中的单个文件

4、安装完毕之后我们可以通过一些配置，用它替代 rm命令

1. [root@VM_54_118_centos ~]# vim .bashrc
2. # .bashrc
3. #alias rm='rm -i'
4. alias rm='trash-put'

5、实验测试

删除测试：

1. [root@VM_54_118_centos ~]# rm -rf dump.rdb
2. [root@VM_54_118_centos ~]# ll ~/.local/share/Trash/files
3. -rw-r--r-- 1 root root 123 Jul 17 2018 dump.rdb
4. [root@VM_54_118_centos ~]# trash-list
5. 2019-02-02 18:02:33 /root/dump.rdb

还原删除的文件

1. [root@VM_54_118_centos ~]# trash-restore /root/dump.rdb
2. 0 2019-02-02 18:01:08 /root/dump.rdb.bak
3. 1 2019-02-02 18:02:33 /root/dump.rdb
4. What file to restore [0..1]: 1
5. 还原成功
6. [root@VM_54_118_centos ~]# ll /root/dump.rdb
7. -rw-r--r-- 1 root root 123 Jul 17 2018 /root/dump.rdb

备注：

trash-put命令会把我们想要删除的文件移动到~/.local/share/Trash/files 中。
相关信息记录在~/.local/share/Trash/info中。
