Using a bash shell script (/bin/sh), I need to know how to check to see
if certain files exist in a directory, as in, "Are there any jpegs in
this directory?". I've tried various things (like using -s, -f with
test and a do/for loop) but nothing seems to work right. The closest I
can come is
if test `ls /opt/images/*.jpg | wc -l` -gt 0 then ...
Unfortunately, this gives me the error message "ls: /opt/images/*.jpg:
No such file or directory" when there are no jpegs in /opt/images.
So what am I missing here?
