Linux recycle bin [rewrite rm to prevent files from being recovered by mistake]

Rm-rf is more careful when using commands. it often goes by the river. it is inevitable that the shoes will be wet. yesterday, a wrong hand, wrong command, put the folder you originally wanted to keep to rm-rf for a few days of painstaking efforts, rely on, and the heart of death has gone through Baidu, google, and try to be fruitless, ah, how can I find it later... capital

 

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.
