count - count the number of elements of an array
==========================================
Synopsis
--------
count $VARIABLE
Description
------------
``count`` prints the number of arguments that were passed to it. This is usually used to find out how many elements an environment variable array contains.
``count`` does not accept any options, not even ``-h`` or ``--help``.
``count`` exits with a non-zero exit status if no arguments were passed to it, and with zero if at least one argument was passed.
Example
------------
::
count $PATH
# Returns the number of directories in the users PATH variable.
count *.txt
# Returns the number of files in the current working directory ending with the suffix '.txt'.
