Tool-trash-RM in Linux

Using RM to delete files in Linux will do bad things accidentally ...... For example, if you accidentally delete the system file, you may have an idea about whether to bind the RM deletion action to the garbage bin. In this case, you can find it again if you delete the System File incorrectly.

I searched the internet and found someone has done this. I have reposted it for your reference.

Original post in this http://www.webupd8.org/2010/02/make-rm-move-files-to-trash-instead-of.html

1. Install trash-cli

This package provides a command line interface trashcan
Utility compliant with the freetier top.org trash specification. it
Remembers the name, original path, deletion date, and permissions
Each trashed file.

In ubuntu, simply run this command:

sudo apt-get install trash-cli

2. Set up the script
In Ubuntu enter this in a terminal:
sudo gedit /usr/local/bin/trash-rm

And paste this in the newly opened file, then save it:
 1 #!/bin/bash
 2  # command name: trash-rm
 3 shopt -s extglob
 4 recursive=1
 5 declare -a cmd
 6 ((i = 0))
 7 for f in "$@"
 8 do
 9 case "$f" in
10 (-*([fiIv])r*([fiIv])|-*([fiIv])R*([fiIv]))
11 tmp="${f//[rR]/}"
12 if [ -n "$tmp" ]
13 then
14 #echo "\$tmp == $tmp"
15 cmd[$i]="$tmp"
16 ((i++))
17 fi
18 recursive=0 ;;
19 (--recursive) recursive=0 ;;
20 (*)
21 if [ $recursive != 0   -a  -d "$f" ]
22 then
23 echo "skipping directory: $f"
24 continue
25 else
26 cmd[$i]="$f"
27 ((i++))
28 fi ;;
29 esac
30 done
31 trash "${cmd[@]}"

Then make it executable by opening a terminal and running this:
sudo chmod +x /usr/local/bin/trash-rm

3. Create an alias for "rm" to use "trash-rm"
In Ubuntu, run this in a terminal:
gedit ~/.bashrc

and enter this at the end of the file:
alias rm="trash-rm"

and save it.
Then reload bashrc by running the following command in a terminal:
bash

That's it! Now try it out by deleting files the way you always do, using "rm" and "rm -r".
Final trash-cli tips
Since you've installed the trash-cli utility, now you can use the
following commands for manipulating the trash from the command line (the
 names are self explanatory):
empty-trashlist-trashrestore-trash

Update: to get this to work for "sudo rm" as well, copy wilo108's sudo wrapper in your ~/.bashrc file. Without it, this will not work when "rm" is used with "sudo"!
