二、開始安裝

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

 

三、安裝成功後咱們的系統就有了如下工具.

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

功能說明：

trash-put 將文件或目錄移入回收站
trash-empty 清空回收站
trash-list 列出回收站中的文件
trash-restore還原回收站中的文件
trash-rm 刪除回首站中的單個文件

 

四、安裝完畢以後咱們能夠經過一些配置，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'

 

五、實驗測試

刪除測試：

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.  
5. [root@VM_54_118_centos ~]# trash-list
6. 2019-02-02 18:02:33 /root/dump.rdb

還原刪除的文件

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.  
6. 還原成功
7. [root@VM_54_118_centos ~]# ll /root/dump.rdb
8. -rw-r--r-- 1 root root 123 Jul 17 2018 /root/dump.rdb

備註：

trash-put命令會把咱們想要刪除的文件移動到~/.local/share/Trash/files 中。相關信息記錄在~/.local/share/Trash/info中。
