+# Iterate over globs whenever possible (e.g. 'for f in */*.wav'), as for loops over ls will fail for filenames like 'my file*.txt'.
+
+### Problematic code:
+
+    for f in $(ls *.wav)
+    do
+      echo "$f"
+    done
+
+### Correct code:
+
+    for f in *.wav
+    do
+      echo "$f"
+    done
+
+### Rationale:
+
+When looping over a set of files, it's always better to use globs when possible. Using command expansion causes word splitting and glob expansion, which will cause problems for certain filenames (typically first seen when trying to process a file with spaces in the name). 
+
+The following files can or will break the first loop:
+
+    touch 'filename with spaces.wav'
+    touch 'filename with * globs.wav' 
+    touch 'More_Globs[2003].wav'
