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

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

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。
