Bash script, im still new to linux

How to append an existing file?
The existing file in the mywastebasket will have the version number zero appended to it and the newly deleted file will have version number 1 appended to it.
How the loop looks like?

My code be like

#!/bin/sh
read file
mv $file mywastebasket
rm -i /home/himeose/mywastebasket/
So how am i gonna proceed?

Read file from home
At /home/himeose/mywastebasket
I will code this after the bash done
touch home.txt
bash delete.sh
home.txt
Are you sure to delete or not? y

Move the file (at home) to directory (mywastebasket is dir)

Yes we are at /home/himeose/

After rm - i /home/himeose/mywastebasket/

The loop
Mybe i should use
If [ conditional expression1 ]
then
statement1
statement2
.
elif [ conditional expression2 ]
then
statement3
statement4
.
.
.
else
statement5
fi

After the file name appended

I can clear all the file in the mywastebasket dir.
By using alias rm - c = "rm -v"
