create vcgencmd command list from Raspberry Pi

# This creates a sorted single column list of commands which can be used with 
# vcgencmd.

# The output of vcgencmd commands is a single variable with commands separated
# by commas.
#
# The cut command treats everything within the quotations as a single field and
# prints that.
#
# The awk command is instructed to use ', ' as a record separator, then prints
# each record.
#
# The sort command, does just that.
#
# The sed command deletes empty lines. For some reason awk creates an empty line
# when it produces it's output.
