Checking if a file is readable and exists in one if condition: if [[ -r -f “/file.png” ]]

Question

I was writing an if statement which checked if a file is readable and exists by doing the following:

if [[ -r \"$upFN\" && -f \"$upFN\" ]]; then
....
fi
         


        

Answer 1

Is there ever a case where a file would be readable but it doesn't exist? Don't bother checking for existence when readability will tell you all you need.
