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 $

If you want to use test instead of [], then you can use ! to get the negation:

if ! test "$FILE"; then
  echo "does not exist"
