Detailed explanation of the implementation process and usage of the Linux Recycle Bin mechanism

Preface:

rm under Linux system is irreversible. There is nothing wrong with the command design itself. The problem is that we are usually very confident and like to use rm -rf when executing. This is very dangerous. If the command is executed incorrectly or even the directory is executed incorrectly, it will cause a lot of trouble. At the least, it will lead to overtime work and waste of manpower and material resources. At the worst, it will affect the company's business and even lead to the risk of dismissal. The Recycle Bin mechanism under Windows is a very good strategy, but Linux does not have it. Then we can create one manually and execute it directly:

mkdir -p ~/.Trash
cat >>~/.bashrc<<EOF
#add by caimengzhi at $(date +%F) for Linux trash start
alias rm=trash
alias rl='ls ~/.Trash' 
alias ur=undelfile
undelfile() 
{ 
 mv -i ~/.Trash/\$@ ./ 
} 
trash() 
{ 
 mv \$@ ~/.Trash/ 
}
cleartrash() 
{ 
  read -p "Clear trash?[n]" confirm 
[ \$confirm == 'y' ] || [ \$confirm == 'Y' ] && /usr/bin/rm -rf ~/.Trash/* 
}
#add by caimengzhi at $(date +%F) for Linux trash end
EOF
source ~/.bashrc

illustrate:

1. ~/.Trash is where deleted files and folders are moved to, that is, the Recycle Bin

2. \$confirm means to implement verification, which means that the last thing in the file is $confirm. Among them, \$@ is the same

3. The above function, to put it simply, is to rename the command rm.

Use syntax:

rm (delete), ur (undo), rl (list recycle bin), cleartrash (empty recycle bin) commands.

#Delete a folder and the files will be moved to the Recycle Bin.

$rm filedirctory

#Delete a file

$rm file.txt

#Undo the deletion of file.txt

$ur file.txt

#Remove the filedirctory folder

$ur filedirctory

# List the recycle bin

$rl

#Empty the Recycle Bin

cleartrash

OK, that's the basic content. In essence, it just replaces the root user's rm command with the mv command. If the system has established other users, you also need to use that user to re-execute the above command. It depends on the situation. If you lose the root privilege, then the power of rm -rf is nothing to be afraid of. Of course, we also need to execute the regular rm command. How to do it? This is ok:

/usr/bin/rm -rf
