Working With Files
To display a directory of the files stored on the router, in both FLASH and NVS,
use the command:
SHOW FILE
To limit the display to certain files, use the command:
SHOW FILE=filename
filename may contain wildcard characters. Files can be permanently deleted
using the command:
DELETE FILE=filename
filename may contain wildcard characters. Files can be created using the
router’s built-in editor, using the command:
EDIT [filename]
or by downloading the file via HTTP, TFTP or ZMODEM, using the command:
LOAD FILE=filename
FLASH File System
The FLASH File System (FFS) provides additional functionality on top of that
provided by the file subsystem, to manage the peculiarities of FLASH
technologies. The additional functionality of the FFS includes:
■
Header and data integrity is ensured with a checksum mechanism.
■
All FLASH processes can recover from a power cycle without data loss.
■
Automatic recovery of deleted file space by the compaction process.
Information about the state of the FFS can be displayed using the command:
SHOW FLASH
Working with FFS Files
FFS files can be managed like any other file on the router, using the standard
file subsystem commands:
EDIT [filename]
DELETE FILE=filename
LOAD FILE=filename
SHOW FILE[=filename]
In addition, the following commands can be used to manage files stored in
FLASH memory. To display a directory of the files stored in FLASH memory,
use the command:
SHOW FFILE [CHECK]
If CHECK is specified then the file data checksum is also verified. This is
included as an option because it can take some time to complete a check on large
files. A file data check is also carried out each time a file is read by the system.
A FLASH file can be deleted with the command:
DELETE FFILE=filename
