How do I tell if a regular file does not exist in Bash? 17 answers

No need to use find in case your file is in current path itself, following may help you.

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

Then run script as script.ksh file_name Also in case you need to verify if file exists and is having some size then change -f to -s in above code.

You could also do man test for checking all these kind of conditions too in your box.
