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

This uses ls(1), if no flac files exist, ls reports error and the script exits; othewise the script continues and the files may be be processed

#! /bin/sh
ls *.flac  >/dev/null || exit
## Do something with flac files here
