运维中, 删除文件都要慎重, 所以, windows的回收站功能有时候也是非常有必要的.

trash是一个项目, 可以实现类似windows的回收站功能. 只要我们安装了trash, 将rm重新建立别名, 就能用trash来实现文件的安全删除和恢复.

第一步: 安装

[root@localhost ~]# easy_install trash-cli
Searching for trash-cli
Reading https://pypi.python.org/simple/trash-cli/
Best match: trash-cli 0.17.1.14
Downloading https://files.pythonhosted.org/packages/d5/a2/2be332ce279d6889adb69dd71172ac8f48fd441900a15546253287638f1e/trash-cli-0.17.1.14.tar.gz#sha256=b0a06ca15d05e70de00f4c19a79ec677f4ae9f29e20d6d3e09c2494a00650007

第二步: 了解功能

trash              
trash-put           trashes files and directories, 删除文件目录
trash-empty         empty the trashcan(s), 清空回收站
trash-list          list trashed file, 列出删除的文件
trash-restore       restore a trashed file, 重新恢复删除的文件到一个目录
trash-rm            remove individual files from trash can, 删除回收站的个别文件

第三步: 测试各个功能

[root@localhost ~]# mkdir test   # 创建测试环境
[root@localhost ~]# cd test
[root@localhost test]# touch {1,2,3,4}.txt
[root@localhost test]# ls
1.txt  2.txt  3.txt  4.txt
[root@localhost test]# mkdir test_dir
[root@localhost test]# ls
1.txt  2.txt  3.txt  4.txt  test_dir

[root@localhost test]# trash 1.txt   # 删除文件
[root@localhost test]# ls
2.txt  3.txt  4.txt  test_dir

[root@localhost test]# trash test_dir/   # 删除目录
[root@localhost test]# ls
2.txt  3.txt  4.txt

[root@localhost test]# trash-list    # 查看回收站
2018-07-31 18:42:49 /root/test/1.txt
2018-07-31 18:42:54 /root/test/test_dir

[root@localhost test]# trash-empty    # 清空回收站
[root@localhost test]# ls
2.txt  3.txt  4.txt
[root@localhost test]# trash-list
空....

[root@localhost test]# trash *   # 删除所有文件
[root@localhost test]# trash-list   # 查看删除后的列表
2018-07-31 18:47:37 /root/test/2.txt
2018-07-31 18:47:37 /root/test/3.txt
2018-07-31 18:47:37 /root/test/4.txt

[root@localhost test]# trash-restore   # 交互式恢复文件
   0 2018-07-31 18:47:37 /root/test/2.txt
   1 2018-07-31 18:47:37 /root/test/3.txt
   2 2018-07-31 18:47:37 /root/test/4.txt
What file to restore [0..2]: 0    # 输入id回车
[root@localhost test]# ls         # 恢复成功
2.txt

[root@localhost test]# trash-list
2018-07-31 18:47:37 /root/test/3.txt
2018-07-31 18:47:37 /root/test/4.txt

[root@localhost test]# trash-rm 3.txt    # 删除单个文件
[root@localhost test]# trash-list
2018-07-31 18:47:37 /root/test/4.txt

第四步: 别名替换

alias rm='trash'

如此这般, 删除文件后就不会直接丢失.

后续的功能, 读者自己搞, 应该也能高出自己的花样. 这里就不赘述了.
