Write a shell script that gets 6 arguments. The first 3 parameters are the names of 3 files and the second 3 arguments are the permissions for them. The script should create the files and set their permissions. Example: If we run the script like this: ./script.sh file1 file2 file3 777 644 755 The script should create file1 with permissions 777, file2 with permissions 644 and file3 with permissions 755.
