linux replace rm command to prevent accidental deletion

1. Create a directory under / home / username / directory named: .trash

2 .. at / home / username / tools / directory, create a shell document, named: remove.sh

#！/bin/bash
PARA_CNT=$#
TRASH_DIR="/home/username/.trash"
for i in $*; do
STAMP=`date +%s`
fileName=`basename $i`
mv $i $TRASH_DIR/$fileName.$STAMP
done

 3. Modify ~ / .bashrc, add the line (if the root user to modify / etc / profile)

alias rm="sh /home/username/tools/remove.sh"

4. Set the crontab, periodically empty trash, such as:

crontab -e
0 0 * * * rm -rf /home/username/.trash/*

5. source ~ / .bashrc so that replacement takes effect immediately (root user source / etc / profile)

For ease of use, it was made into a button xshell

mkdir -p /home/username/.trash
mkdir -p /home/username/tools

 cat << EOF >  remove.sh
> #! /bin/bash
> PARA_CNT=$#
> TRASH_DIR="/home/username/.trash"
> for i in $*; do
> STAMP=`date +%s`
> fileName=`basename $i`
> mv $i $TRASH_DIR/$fileName.$STAMP
> done
> EOF
