#!/usr/bin/env bash
# Note the use of env. This is because executables may not be placed in the same place on all systems. Notoriously, bsd (and thus mac osx) differs from linux. However, /usr/bin/env always exists in the same place, and it can tell you where other executables are. Thus, the above is good style for portability.

# Convention is to put variables in uppercase in shell script. The $() syntax is generally more readable
# You can embed a variable in a string, using the ${VAR_NAME} syntax
