Viewing Files on the Local File System

This section describes how to view a variety of files.

Viewing the Contents of a Local Device

The contents, usage information, and file system directory structure of any local device can be viewed by
entering the following command at the Exec mode prompt:
directory { /flash | /usb1 | /hd-raid }

Viewing CLI Configuration and boot.sys Files

The contents of CLI configuration and boot.sys files, contained on the local file system, can be viewed off-line
(without loading them into the OS) by entering the following command at the Exec mode prompt:
[local]
Where: url is the path name for the location of the file and filename is the name of the file, including any
extension.

Validating an Operating System File

The operating system software image file, identified by its .bin extension, is a non-readable, non-editable file
that executes on the system, creating its runtime operating system (OS).
It is important to verify a new operating system image file before attempting to load it. To accomplish this, a
proprietary checksum algorithm is used to create checksum values for each portion of the application stored
within the .bin file during program compilation.
This information can be used to validate the actual file against the checksum values stored within the file
during its compilation. If any portion of the image file has become corrupted (for example, the file was
truncated or was transferred using ASCII mode instead of binary mode), then this information is reported and
the file is deemed unusable.
To validate an operating system software image file, enter the following command at the Exec mode prompt:
[local]
The output of this command displays the following information:
• Version number
• Description
host_name configure /flash/clearcmds.cfg
#
host_name show file url { /flash | /usb1 | /hd-raid } filename
#
Operator and inspector-level users can execute the show file command but cannot execute the directory
command.
host_name show version { /flash | /usb1 | /hd-raid } /[directory]/filename [all]
