This section is a glossary of murex builtin commands.
Because murex is loosely modelled on the functional paradigm, it means all language constructs are exposed via functions and those are typically builtins because they can share the murex runtime virtual machine. However any executable command can also be called from within murex; be that either via the exec builtin or natively like you would from any Linux, UNIX, or even Windows command prompt.
In murex's source under the lang/builtins path of the project files is several directories, each hosting different categories of murex builtins. From core commands through to data-types and methods.
Each package will include a README.html file with a basic summary of what that package is used for and all you to enable or disable builtins, should you decide to compile the shell from source.
From the shell itself: run builtins to list the builtin command.
If you require a manual on any of those commands, you can run murex-docs to return the same markdown-formatted document as those listed below. eg
murex-docs trypipe!
