-f file-name - Take Input From a File

Use the -f option to supply input to mpadmin from the file specified by the file-name argument. The source file is expected to consist of one or more mpadmin commands, one command per line.

This option can be particularly useful in the following ways:

• It can be used following use of the mpadmin command dump, which outputs all or part of a cluster's configuration in the form of an mpadmin script. If the dump output is stored in a file, mpadmin can, at a later time, read the file via the -f option, thereby reconstructing the configuration that had been saved in the dump output file.

• The -f option can also be used to read mpadmin scripts written by the system administrator--scripts designed to simplify other cluster management tasks that involve issuing a series of mpadmin commands.
