<row>

<entry><p> <codeph>-X</codeph>  </p> </entry>

<entry><p>Can be used only inside a shell function, and may not be followed

by a name. It causes the calling function to be marked for autoloading and

then immediately loaded and executed, with the current array of positional

parameters as arguments. This replaces the previous definition of the function.

If no function definition is found, an error is printed and the function remains

undefined and marked for autoloading. </p> </entry>

</row>

<row>

<entry><p> <codeph>+X</codeph>  </p> </entry>

<entry><p>Attempts to load each name as an autoloaded function, but does not

execute it. The exit status is zero (success) if the function was not previously

defined and a definition for it was found. This does not replace any existing

definition of the function. The exit status is nonzero (failure) if the function

was already defined or when no definition was found. In the latter case the

function remains undefined and marked for autoloading. </p> <p>It can also

be combined with either <codeph>-k</codeph> or <codeph>-z</codeph> to make

the function be loaded using <codeph>ksh-style</codeph> or <codeph>zsh-style</codeph> autoloading,

respectively. If neither is given, the current setting of the <codeph>KSH_AUTOLOAD </codeph> options

determines how the function is loaded. With <codeph>ksh-style</codeph> autoloading,

the contents of the file will not be executed immediately. Instead, the function

created will contain the contents of the file plus a call to the function

itself appended to it, thus given normal <codeph>ksh</codeph> autoloading

behaviour on the first call to the function. </p> </entry>
