This is the command mhparammh that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
mhparam - print nmh profile and context components
mhparam [components] [-all] [-component | -nocomponent] [-version] [-help] [-debug]
mhparam writes the value of the specified profile component to the standard output
separated by newlines. Component name matching is case-insensitive. If the profile
component is not present, the default value (or nothing if there is no default) is
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
If -all is specified, then all components in the nmh profile are displayed and other
arguments are ignored.
mhparam can provide other information, such as the nmh version identifier, the locations
of the nmh etcdir and libdir install directories, all proc settings, and the datalocking
method described in the mh-profile(5) man page. Information about the configuration of
the nmh installation is also available, including the default mail spool locking method.
To test whether the configuration includes support for SASL, TLS, and iconv(3), the
following commands, respectively, will output a non-null string to indicate support:
Conversely, no output means that the specified support is not included. The -debug switch
displays all such other information available from mhparam.
% mhparam path
% mhparam mhlproc
% mhparam -component Path
% mhparam AliasFile rmmproc
% mhparam -nocomponent AliasFile rmmproc
% mhparam path nonexistent context
% mhparam version
% mhparam etcdir
% mhparam libdir
% mhparam spoollocking
% mhparam datalocking
% mhparam sasl
% mhparam tls
% mhparam iconv
mhparam is also useful in backquoted operations:
% fgrep cornell.edu `mhpath +`/`mhparam aliasfile`
mhparam returns the number of components that were not found.
