How do I tell if a regular file does not exist in Bash?

Question

I\'ve used the following script to see if a file exists:

#!/bin/bash

FILE=$1     
if [ -f $FILE ]; then
   echo \"File $FILE exists.\"
else
   echo \"File $

It's worth mentioning that if you need to execute a single command you can abbreviate

if [ ! -f "$file" ]; then
    echo "$file"
fi

to

test -f "$file" || echo "$file"

or

[ -f "$file" ] || echo "$file"
