MHPARAM(1)MHPARAM(1)NAMEmhparam - print nmh profile and context components
SYNOPSISmhparam [components] [-all] [-component | -nocomponent] [-version]
[-help] [-debug]
DESCRIPTIONmhparam 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 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 spec‐
ified, then the switch -nocomponent is on by default.
If -all is specified, then all components in the nmh profile are dis‐
played and other arguments are ignored.
mhparam can provide other information, such as the nmh version identi‐
fier, the locations of the nmh etcdir and libdir install directories,
all proc settings, and the datalocking method described in the mh-pro‐
file(5) man page. Information about the configuration of the nmh
installation is also available, including the default mail spool lock‐
ing 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:
mhparam sasl
mhparam tls
mhparam iconv
Conversely, no output means that the specified support is not included.
The -debug switch displays all such other information available from
mhparam.
Examples:
% mhparam path
Mail
% mhparam mhlproc
/usr/local/libexec/nmh/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 version

% mhparam etcdir

% mhparam libdir

% mhparam spoollocking

% mhparam datalocking

% mhparam iconv

mhparam is also useful in backquoted operations:
% fgrep cornell.edu `mhpath +`/`mhparam aliasfile`
EXIT STATUSmhparam returns the number of components that were not found.
