Centos rm Recycle Bin

Centos rm Recycle Bin

After linux rm deletes a file, it is troublesome to restore it. Even if it is restored, the file name format is changed to a string of numbers.

Modify the environment variable of the root user

Vi ~ /. Bashrc

Comment out the alias for line 1

# Alias rm = 'rm-I'

Add the following content to the last line:

Mkdir-p ~ /. Trash

Alias rm = trash

Alias r = trash

Alias rl = 'ls ~ /. Trash'

Alias ur = undelfile

Undelfile ()

{

Mv-I ~ /. Trash/$ @./

}

Trash ()

{

Mv $ @~ /. Trash/

}

Cleartrash ()

{

Read-p "clear sure? [N] "confirm

[$ Confirm = 'y'] | [$ confirm = 'y'] &/bin/rm-rf ~ /. Trash /*

}

Reload Environment Variables

Although rm is defined by an alias, it can be an absolute path to delete files.

For example,/bin/rm 1.txt

It is not saved to the. trash directory.

If you need to define automatic cleanup of files deleted for 7 days

You can write a script.

#! /Bin/bash

Find/root/. trash-ctime 7-type f-name "*"-exec/bin/rm {}\;

In addition to the root user in Linux, other users need to log on to the server and want to use the recycle bin mechanism.

System environment variables can be modified.

Vi/etc/profile

Add the last line

Mkdir-p ~ /. Trash

Alias rm = trash

Alias r = trash

Alias rl = 'ls ~ /. Trash'

Alias ur = undelfile

Undelfile ()

{

Mv-I ~ /. Trash/$ @./

}

Trash ()

{

Mv $ @~ /. Trash/

}

Cleartrash ()

{

Read-p "clear sure? [N] "confirm

[$ Confirm = 'y'] | [$ confirm = 'y'] &/bin/rm-rf ~ /. Trash /*
