A safe rm

From Augix' Wiki

write a file: ~/rm.sh

#!/bin/bash
#
#  A tiny script that moves files to a wastebasket, rather than deleting them
#+ (and doesn't overwrite previously deleted files of the same name).
 
[ -d ~/Trash ]
if [ $? -eq 1 ]; then
    echo "Creating directory."
    mkdir ~/Trash;
fi
 
random_suffix=$RANDOM
 
for file in $@; do
    if [[ -e ~/Trash/$file ]]; then
        mv $file ~/Trash/${file}.${random_suffix}
    else mv $file ~/Trash/
    fi
done

modify ~/.bashrc

alias remove='/bin/rm'
alias rm='~/rm.sh'
