NAME¶
mhparam - print nmh profile and context components
SYNOPSIS¶
mhparam [components] [-all]
[-component | -nocomponent] [-version] [-help]
[-debug]
DESCRIPTION¶
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 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.
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:
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/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 version
nmh-1.6
% mhparam etcdir
/etc/nmh
% mhparam libdir
/usr/lib/mh
% mhparam spoollocking
fcntl
% mhparam datalocking
fcntl
% mhparam sasl
cyrus_sasl
% mhparam tls
tls
% mhparam iconv
iconv
mhparam is also useful in backquoted operations:
% fgrep cornell.edu `mhpath +`/`mhparam aliasfile`
EXIT STATUS¶
mhparam returns the number of components that were not found.
