shell script to remove a file if it already exist

Question

I am working on some stuff where I am storing data in a file. But each time I run the script it gets appended to the previous file.

I want help on how I can remove the f

Answer 1

Something like this would work

#!/bin/sh

if [ -fe FILE ]
then 
    rm FILE
fi 

-f checks if it's a regular file

-e checks if the file exist

Introduction to if for more information

EDIT : -e used with -f is redundant, fo using -f alone should work too
