Check whether a certain file type/extension exists in directory

Question

How would you go about telling whether files of a specific extension are present in a directory, with bash?

Something like

if [ -e *.flac ]; then 
echo t         


        

Answer 1

shopt -s nullglob
if [[ -n $(echo *.flac) ]]    # or [ -n "$(echo *.flac)" ]
then 
    echo true
fi
