Check for file existance by mask
for f in /path/to/your/files*; do
## Check if the glob gets expanded to existing files.
## If not, f here will be exactly the pattern above
## and the exists test will evaluate to false.
if [ -e "$f" ] then
echo "Mask exists"
fi
## This is all we needed to know, so we can break after the first iteration
