# 18. Open MPI manual pages

All of the content in this section is also installed as individual manual (“man”) pages in an Open MPI installation. If your man page search path includes the location where Open MPI installed its man pages (which defaults to `$prefix/share/man`), you can invoke commands similar to the following to see the same content that you see in these HTML pages:

    shell$ man MPI_Send
