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 $         


        

Answer 1

To test file existence, the parameter can be any one of the following:

-e: Returns true if file exists (regular file, directory, or symlink)
-f: Returns true if file exists and is a regular file
-d: Returns true if file exists and is a directory
-h: Returns true if file exists and is a symlink

All the tests below apply to regular files, directories, and symlinks:

-r: Returns true if file exists and is readable
-w: Returns true if file exists and is writable
-x: Returns true if file exists and is executable
-s: Returns true if file exists and has a size > 0

Example script:

#!/bin/bash
FILE=$1

if [ -f "$FILE" ]; then
   echo "File $FILE exists"
else
   echo "File $FILE does not exist"
