You can also ask for help on a particular function name. For example,
|
|
|
|
help asinh
|
|
help round
|
|
|
|
or on a particular symbol such as:
|
|
|
|
help =
|
|
|
|
For example:
|
|
|
|
help usage
|
|
|
|
will print the calc command usage information. One can obtain calc help
|
|
without invoking any startup code by running calc as follows:
|
|
|
|
calc -q help topic
|
|
|
|
where 'topic' is one of the topics listed above.
|
|
|
|
If the -m mode disallows opening files for reading or execution of programs,
|
|
then the help facility will be disabled. See:
|
|
|
|
help usage
|
|
|
|
for details of the -m mode.
|
|
|
|
The help command is able to display installed help files for custom builtin
|
|
functions. However, if the custom name is the same as a standard help
|
|
file, the standard help file will be displayed instead. The custom help
|
|
builtin should be used to directly access the custom help file.
|
|
|
|
For example, the custom help builtin has the same name as the standard
|
|
help file. That is:
|
|
|
|
help help
|
|
|
|
will print this file only. However the custom help builtin will print
|
|
only the custom builtin help file:
|
|
|
|
custom("help", "help");
|
|
|
|
will by-pass a standard help file and look for the custom version directly.
|
|
|
|
As a hack, the following:
|
|
|
|
help custhelp/anything
|
|
|
|
as the same effect as:
|
|
|
|
custom("help", "anything");
|
