How to prevent accidental deletion in Linux

1. Create a new directory in the /home/username/ directory and name it: .trash

2.. Create a new shell file in the /home/username/tools/ directory and name it: remove.sh

Copy code The code is as follows:

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 and add a line

Copy code The code is as follows:

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

Use Our self-built remove.sh replaces the rm command

4. Set up crontab and empty the trash can regularly, such as:

Copy code The code is as follows:

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

Clear it at 0 o'clock every day Trash bin

5. source ~/.bashrc makes the replacement take effect immediately

After the above steps, the files deleted by executing rm will be placed in the trash bin. If deleted by mistake, you can recover from it.
