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.
