MHPARAM(1)                                                           [nmh-1.5]                                                          MHPARAM(1)

NAME

       mhparam - print nmh profile and context components

SYNOPSIS

       mhparam [components] [-all] [-component | -nocomponent] [-version] [-help]

DESCRIPTION

       mhparam  writes the value of the specified profile component to the standard output separated by newlines.  If the profile component is not
       present, the default value (or nothing if there is no default) is printed.

       If the switch -component is given, then the component name is displayed along with the profile components value.  This can be disabled with
       the switch -nocomponent.

       If  more  than  one  component  is specified in the components list, then the switch -component is on by default.  If only one component is
       specified, then the switch -nocomponent is on by default.

       If -all is specified, then all components in the nmh profile are displayed and other arguments are ignored.

       Examples:

            % mhparam path
            Mail

            % mhparam mhlproc
            /usr/lib/mh/mhl

            % mhparam -component Path
            Path: Mail

            % mhparam AliasFile rmmproc
            AliasFile: aliases
            rmmproc: rmmproc

            % mhparam -nocomponent AliasFile rmmproc
            aliases
            rmmproc

            % mhparam path nonexistent context
            Path: Mail
            context: context

       mhparam is also useful in back-quoted operations:

            % fgrep cornell.edu `mhpath +`/`mhparam aliasfile`

EXIT STATUS

       mhparam returns the number of components that were not found.
