The big question is "What's writing the file?"
If it's a samba share for instance, or a samba printer queue you should do
"man smb.conf" and search for "print command".
Other things that can be done, have the app touch another file when
finished like filename.pdf.go
Your polling routine might look like this:-
while [ 0 ]; do
for TAG in *.go; do
PDF=`echo "$TAG" | sed -e "s/\.go$//"`
process $PDF
rm $PDF $TAG
done
sleep 10
done
Or a more complex answer would be to write a quick program using fam (see
man fam).
