HSI Overview

Previous


HSI provides a Unix shell-style interface to the High Performance Storage System.

Directories and files can be listed using the "ls" command, and traversing directories can be accomplished with the "cd" command.  


When HSI is launched, it performs the following actions:


1. Parses command line options (see HSI Command Line Options in the HSI Reference Manual for more details)


2. reads startup files (the user's $HOME/.hsirc, and the system-wide hsirc file that is optionally installed by the system administrator), if they exist.  In general, most settings that are defined in the system-wide hsirc file can be overridden by the user's private .hsirc file.


3. authenticates using one of the mechanisms that were enabled when the application was compiled, such as kerberos or a username/password combination.  There are several ways to override the default mechanism, as described in the HSI Authentication section.
