\section count count - count the number of elements of an array

\subsection count-synopsis Synopsis
\fish{syn}
count $VARIABLE
\endfish

\subsection count-description 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, including '`-h`'.

`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.

\subsection count-example Example

<pre>
count $PATH
</pre>

returns the number of directories in the users PATH variable.

<pre>
count *.txt
</pre>

returns the number of files in the current working directory ending with the suffix '.txt'.

Implement count as ashellscript function instead of a command in order to support very long argument lists. Note that this implementation is painfully slow for more than 1000 arguments. darcs-hash:20070423220026-ac50b-69c4b06c88e6120429b6358f1b61f6076d392ce5.gz 2007-04-24 06:00:26 +08:00			`passed to it.
