Please provide screenshots and commands

I tried this for number 2 but it didn't work.

echo "Please enter your filename:" read filepath find $filepath -type f -size +100M

1. Create a script that prompts the user for a filename. It then creates an empty file with given name in the current directory. It also displays message to user that file has been created. 2. Create a script that accepts full path to a directory and searches for all files bigger than 100MB
