This file describes the current list of modules distributed with pdsh. Pdsh modules come in two flavors at this time: rcmd and miscellaneous. The rcmd modules provide remote command functionality for pdsh, while the "misc" modules extend the functionality of pdsh in some other way -- by providing new options to pdsh or modifying the pdsh working collective, for example. Multiple rcmd modules may be installed at once and are chosen at runtime by either the '-R type' option to pdsh, or by setting the environment variable PDSH_RCMD_TYPE. When pdsh initializes it reads all available modules from the `pkglibdir' (typically /usr/lib/pdsh or /usr/local/lib/pdsh). If conflicting modules are installed, they are loaded on a first-come first-serve basis (i.e. the first module loaded wins). Modules may be force-initialized by specifying them to the '-M' pdsh/pdcp option, or via the PDSH_MISC_MODULES environment variable.
