 # Compute Halstead
 * Run the provided *halstead.sh*: `halstead source output-file`
 	* Name the output file *tokens.txt*
-* Use `uniq`, `wc`, etc. as needed to compute [Halstead]'s Length, Vocabulary, Estimated length, and Purity Ratio
+* Use `uniq`, `wc`, etc., as needed to compute [Halstead]'s Length, Vocabulary, Estimated length, and Purity Ratio
 	* Commit and push the output-file (i.e., *tokens.txt*) to GitHub
 	* Answer Halstead metrics in Canvas 
 
 # Some Tips
 * Since in alphabetical order, front tokens are all operators except strings
 	* Use `grep "'.*'"` to filter out string literals, then look at line the operators end at
 * `word_operators.sh` is provided to filter out word token operators
-* Combine above with: `wc`, `uniq`, etc., as necessary
