 Instead, use a for loop to expand the glob and check each result individually.
 
+If you are looking for the existence of a directory, do:
+
+```sh
+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.
+    [ -e "$f" ] && echo "files do exist" || echo "files do not exist"
+
+    ## This is all we needed to know, so we can break after the first iteration
+    break
+done
+```
