mhparam (1) - Linux Man Pages
mhparam: print nmh profile and context components
mhparam - print nmh profile and context components
- mhparam [components] [-all] [-component | -nocomponent] [-version] [-help] [-debug]
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.
% mhparam path Mail % mhparam mhlproc /usr/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 nmh-1.6 % mhparam etcdir /etc/nmh % mhparam libdir /usr/libexec/nmh % 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 STATUSmhparam returns the number of components that were not found.
