     SH-MLOAD(1)                                           SH-MLOAD(1)

     NAME
          mload, munload - namespace separation for shell modules

     SYNOPSIS
          load mload

          mload name [ path... ]
          munload name [ path... ]

     DESCRIPTION
          Mload is a loadable module for sh(1) that allows the simul-
          taneous use of shell modules with potentially clashing com-
          mand name spaces.  Mload creates a new namespace name and
          loads each path as a builtin module in the same way as load
          (see sh(1)). Any commands or substitution builtins defined
          by the modules are accessible by giving the command and its
          arguments as arguments to the name command.

          Munload unloads a module from the namespace name. If no mod-
          ules remain in the namespace, name is undefined as a com-
          mand.

     EXAMPLE
          Load mpexpr in a different namespace from expr (see sh-
          expr(1)):
          load expr
          mload mp mpexpr
          echo ${expr 1 2 +}
          echo ${mp expr 2 300 xx}

     BUGS
          Because of the way shell modules are implemented, the names-
          paces are global across all processes that share an instance
          of mload.
