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 locations of the nmh
etcdir and libdir install directories and all proc settings. The
-debug switch displays all such other information available from
mhparam.
Examples:
% mhparam path
Mail
% mhparam mhlproc
/usr/lib/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 etcdir
/etc/nmh
% mhparam libdir
/usr/lib
mhparam is also useful in back-quoted operations:
% fgrep cornell.edu `mhpath +`/`mhparam aliasfile`
EXIT STATUSmhparam returns the number of components that were not found.
