Linux/UNIX: Find Out If File Exists With Conditional Expressions

This snippet shows you the script used to find if a file exists.

The script works as follows:

First it we declare the Variable FILE to equal what ever you specify on the command line when you execute the script.
Next step is the test function, we say if (-f) the $FILE (you entered) exists then,
print on the screen file exists else print it does not.

#!/bin/bash
FILE=$1  
 if [ -f $FILE ]; then
   echo \"File $FILE exists\"
    else
   echo \"File $FILE does not exists\"
 fi
