check presence of input file

My script is taking a file "" as input for running the script. My worry is that i need to execute the script only if the file is present, if it's not don't perform the next commands.

Just to have a check at the beginning of the script : If "" exists, then go on. If it's does not exist exit.

[ -s file ]

Read the man page for your shell. It tells you all you need to know.
