MHPARAM(%manext1%)

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
    %libdir%/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.
