mhparam

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.

FILES

       $HOME/.mh_profile	  The user profile
       or $MH			  Rather than the standard profile
       <mh-dir>/context 	  The user context
       or $MHCONTEXT		  Rather than the standard context

PROFILE COMPONENTS

       context: 	    To determine the context file

SEE ALSO

       mh-profile(5)

DEFAULTS

       `-nocomponent' if only one component is specified
       `-component' if more than one component is specified
       `components' defaults to none

CONTEXT

       None
