Linux Recycle Bin (rewrite RM to prevent files from being recovered by mistake)

Rm-RF use with caution

 

The command has been knocked a lot. It often goes by the river, and it is inevitable that the shoes will be wet.

 

Yesterday, by mistake, I typed the wrong command and gave the folder to RM-RF.

 

A few days of hard work, relying on, the heart of death

 

 

Baidu, Google, and fail to get it back.

 

 

Lessons:

 

1. Be careful before RM, especially Rm-RF, or simply rewrite the command.

 

2. Make backup and have convenient backup scripts

 

3. Make a regular backup. One of our predecessors has a regular script and runs it on a regular basis every day. Even if a mistake is deleted, it will not be so miserable.

 

 

First, create a recycle bin.

 

In ~ Add. bashrc or. bash_profile

 

 

Mkdir-P ~ /. Trash

Alias Rm = trash

Alias r = trash

Alias RL = 'ls ~ /. Trash'

Alias ur = undelfile

Undelfile ()

{

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

}

Trash ()

{

MV $ @~ /. Trash/

}

 

This is the execution

Rm is equivalent to executing mV.

 

Note: Rm-RF is already available.

 

The deleted file will appear in. Trash.

 

Can be recovered

 

 

Ur filename

 

 

This poses a problem. How to delete the items in the recycle bin? This is a useful post-RM here.

 

 

 

Add a function under. bashrc just now.

 

 

Cleartrash ()

{

Read-P "Clear sure? [N] "confirm

[$ Confirm = 'y'] | [$ confirm = 'y'] &/usr/bin/Rm-RF ~ /. Trash /*

}

 

$ .. Bashrc

Then, if you want to clear the recycle bin

 

$ Cleartrash.

 

 

Backup script in process

 

Including compress, fast backup, and midnight scheduled backup.

 

Delete files in Linux and fix them. Currently, I have learned how to delete files.
