Command Line Interface (CLI)

PrimoCache includes a command line interface that provides flexible, scriptable access to essential PrimoCache operations from the command shell.

PrimoCache command line tool, rxpcc.exe, is installed in the folder where PrimoCache is installed (for example, C:\Program Files\PrimoCache). For convenience, set your PATH environment variable to include this directory.

The command line tool requires Administrative privileges. On Windows Vista or newer operating systems that have UAC enabled, run it from a Command Prompt window that is launched by performing the following actions:

  • Right-click a Command Prompt shortcut.
  • Click Run As Administrator.

Command Line Syntax

rxpcc <command> [<option>...]

<command>    Specifies a PrimoCache command (see command list below).
<option>...  One or more options that modify a command.

The following conventions are used in the command line tool:

  • Expressions surrounded by angle brackets (<>) are required.
  • Expressions surrounded by square brackets ([]) are optional.
  • Commands are case insensitive, but options are case sensitive.

For the help of this CLI program, type:

rxpcc /?
