How to know if file is deleted and created in bash?

I have a scenario where a script exists to remove files according to the conditions.

Currently the script is like: rem.sh

If [ -e file1 ]; then
    rm -f file1
elif [ -e file2 ]; then
     rm -f file2
 fi

I have another script which calls rem.sh

main.sh

1          rem.sh
2         touch file1
3          xxx
4          xxx
5         xxx
6         rem.sh
7         touch file2

If I run main.sh, It only remove file1 and create file1. Is there way to remove and create file2 and so on?
