How to Build a Safe Linux Trash Bin by Aliasing the rm Command

In Linux the rm command permanently deletes files because the system lacks a built‑in recycle bin, which can lead to accidental data loss, especially when using the force options -f or -rf.

To mitigate this risk you can implement a custom trash can by redefining rm through Bash aliases in the .bashrc file.

Setup steps

vim ~/.bashrc

Append the following lines to the end of the file:

mkdir -p ~/.trash
alias rm=trash
alias r=trash
alias rl='ls ~/.trash/'
alias ur=undelfile

undelfile() {
    mv -i ~/.trash/$@ ./
}

trash() {
    mv -i $@ ~/.trash/
}

cleartrash() {
    read -p "clear sure?[n]" confirm
    [ $confirm == 'y' ] || [ $confirm == 'Y' ] && /bin/rm -rf ~/.trash/*
}

This creates a hidden .trash directory in your home folder and defines four aliases: rm and r now invoke the trash function, which moves specified files to ~/.trash using the interactive -i option to avoid overwriting. rl runs ls ~/.trash/ to list the contents of the trash. ur calls undelfile, which moves selected files back to the current directory. cleartrash prompts for confirmation and then empties the trash with /bin/rm -rf.

Activate the changes

source ~/.bashrc

Now you can safely delete, list, restore, and clear files:

Example workflow

# Create test files
touch file1 file2 file3
# Delete with the new alias
rm file1 file2
r file3
# View trash contents
rl
# Restore files
ur file1
ur file2
ur file3
# Verify restoration
ls
# Empty the trash when needed
cleartrash

While this custom trash provides a safety net, it is still advisable to maintain regular backups to protect against larger mistakes.
