File system management
This chapter provides information about file system management.
Topics in this chapter include:
The file system
The 7705 SAR file system is used to store files used and generated by the system; for example, image files, configuration files, logging files, and accounting files.
The file commands allow you to copy, create, move, and delete files and directories, navigate to a different directory, and display file or directory contents and the image version.
Compact flash device
The file system is based on a DOS file system. On the 7705 SAR, each CSM has an integrated compact flash device. The names for these devices are:
cf3:
cf3-A:
cf3-B:
The first device name above (cf3:) is a relative device name in that it refers to the device local to the control processor on the CSM running the current console session. As in the DOS file system, the colon (‟:”) at the end of the name indicates that it is a device.
The second and third device names (cf3-A: and cf3-B:) are absolute device names that refer directly to the device on CSM A or CSM B (CSM B applies only to chassis with redundant CSMs).
The device cf3-B: does not apply to the following chassis because they do not have redundant CSMs:
7705 SAR-A
7705 SAR-Ax
7705 SAR-M
7705 SAR-H
7705 SAR-Hc
7705 SAR-Wx
7705 SAR-X
The 7705 SAR-8 Shelf V2, 7705 SAR-18, 7705 SAR-H, and 7705 SAR-M have removable compact flash cards.
The 7705 SAR-A, 7705 SAR-Ax, 7705 SAR-Hc, and 7705 SAR-Wx do not have removable compact flash cards; they are shipped with integrated memory that is used to store system boot software, OS software, and configuration files and logs.
The 7705 SAR-X has two removable compact flash cards but they are not field-replaceable. Replacement of the devices is done as a repair service.
On the 7705 SAR-18, cf3: is used to store the software image required for system startup and operation, including the application load. The 7705 SAR-18 CSM also has two optional compact flash slots for two compact flash devices (cf1: and cf2:). These compact flash devices are also referred to as cf1-A:/cf1-B: and cf2-A:/cf2-B: to indicate whether they are on CSM A or CSM B. All the compact flash devices can be used to store software upgrades, statistics, logging files, accounting files, scripts, and configuration data.
URLs
The arguments for the 7705 SAR file commands are modeled after the standard universal resource locator (URL).
A URL can refer to a file (a file-url) or a directory (a directory-url).
The 7705 SAR supports operations on both the local file system and on remote files. For the purposes of categorizing the applicability of commands to local and remote file operations, URLs are divided into three types of URLs: local, FTP, and TFTP
The syntax for each of the URL types is listed in the following table.
URL type |

The 7705 SAR accepts either forward slash (‟/”) or backslash (‟\”) characters to delimit directory and/or filenames in URLs. Similarly, the 7705 SAR SCP client application uses either slash or backslash characters, but not all SCP clients treat backslash characters as equivalent to slash characters. In particular, UNIX systems interpret the backslash character as an ‟escape” character. This causes problems when using an external SCP client application to send files to the 7705 SAR SCP server. If the external system treats the backslash like an escape character, the backslash delimiter gets stripped by the parser and is not transmitted to the 7705 SAR SCP server.
For example, a destination directory specified as ‟cf3:\dir1\file1” is transmitted to the 7705 SAR SCP server as ‟cf3:dir1file1” where the backslash escape characters are stripped by the SCP client system before transmission. On systems where the client treats the backslash like an ‟escape” character, a double backslash ‟\\” or the forward slash ‟/” can typically be used to properly delimit directories and the filename.
Wildcards
The 7705 SAR supports the standard DOS wildcard characters. The asterisk (*) can represent zero or more characters in a string of characters, and the question mark (?) can represent any one character.
Example:
ALU-1>file cf3:\ # copy test*.cfg siliconvalley
cf3:\testfile.cfg
1 file(s) copied.
ALU-1>file cf3:\ # cd siliconvalley
ALU-1>file cf3:\siliconvalley\ # dir
Volume in drive cf3 on slot A has no label.
Directory of cf3:\siliconvalley\
05/10/2006 11:32p <DIR> .
05/10/2006 11:14p <DIR> ..
05/10/2006 11:32p 7597 testfile.cfg
1 File(s) 7597 bytes.
2 Dir(s) 1082368 bytes free.
ALU-1>file cf3:\siliconvalley\ #
As in a DOS file system, the 7705 SAR wildcard characters can only be used in some of the file commands.
Common configuration tasks
The following sections describe the basic system tasks that can be performed.
-
Note: When a file system operation is performed with a command that can potentially delete or overwrite a file system entry (such as a copy, delete, move, rd, or scp command), a prompt appears to confirm the action. The force keyword performs the copy, delete, move, rd, or scp action without displaying the confirmation prompt.
Modifying file attributes
The system administrator can change the read-only attribute in the local file. Enter the attrib command with no options to display the contents of the directory and the file attributes.
Use the following CLI commands to modify file attributes:
- CLI syntax:
file>
attrib
[+r | -r] file-url
The following displays an example of the command syntax:
- Example:
# file
file cf3:\ #
attribfile cf3:\ #
attrib +r BOF.SAVfile cf3:\ #
attrib
The following displays the file configuration:
ALU-1>file cf3:\ # attrib
cf3:\bootlog.txt
cf3:\bof.cfg
cf3:\boot.ldr
cf3:\bootlog_prev.txt
cf3:\BOF.SAV
ALU-1>file cf3:\ # attrib +r BOF.SAV
ALU-1>file cf3:\ # attrib
cf3:\bootlog.txt
cf3:\bof.cfg
cf3:\boot.ldr
cf3:\bootlog_prev.txt
R cf3:\BOF.SAV
Creating and navigating directories
Copying files
Use the copy command to upload or download an image file, configuration file, or other file types to or from a flash card or a TFTP server.
The scp command copies files between hosts on a network. It uses SSH for data transfer, and uses the same authentication and provides the same security as SSH.
The source file for the scp command must be local. The file must reside on the 7705 SAR router. The destination file must be in the format: user@host:file-name. The destination does not need to be local.
Use the following CLI commands to copy files:
- CLI syntax:
file>
copy source-file-url dest-file-url [force]
scp local-file-url destination-file-url [router router name | service-id] [force] [port]
The following displays an example of the copy command syntax:
- Example:
-
ALU-1>file cf3::\ # copy 104.cfg cf3::\test1\test2\test3\test.cfg ALU-1>file cf3::\ # scp file1 admin@192.168.x.x:cf3::\file1 ALU-1>file cf3::\ # scp file2 user2@192.168.x.x:/user2/file2 ALU-1>file cf3::\ # scp cf3::/file3 admin@192.168.x.x:cf3::\file3
Moving files
Use the move command to move a file or directory from one location to another.
Use the following CLI commands to move files:
- CLI syntax:
file>
move old-file-url new-file-url [force]
The following displays an example of the command syntax:
- Example:
ALU-1>file cf3::\test1\test2\test3\ # move test.cfg cf3::\test1 cf3::\test1\test2\test3\test.cfg ALU-1>file cf3::\test1\test2\test3\ # cd .. ALU-1>file cf3::\test1\test2\ # cd .. ALU-1>file cf3::\test1\ # dir Directory of cf3::\test1\ 05/04/2006 07:58a <DIR> . 05/04/2006 07:06a <DIR> .. 05/04/2006 07:06a <DIR> test2 05/04/2006 07:58a 25278 test.cfg 1 File(s) 25278 bytes. 3 Dir(s) 1056256 bytes free. ALU-1>file cf3::\test1\ #
Deleting files and removing directories
Use the delete and rd commands to delete files and remove directories. Directories can be removed even if they contain files and/or subdirectories. To remove a directory that contains files or subdirectories or both, use the rd rf command. When files or directories are deleted, they cannot be recovered.
The force option deletes the file or directory without prompting the user to confirm.
Use the following CLI commands to delete files and then remove directories:
- CLI syntax:
-
file>
delete file-url [force]
rd file-url [force]
The following displays an example of the command syntax:
ALU-1>file cf3::\test1\ # delete test.cfg
ALU-1>file cf3::\test1\ # delete abc.cfg
ALU-1>file cf3::\test1\test2\ # cd test3
ALU-1>file cf3::\test1\test2\test3\ # cd ..
ALU-1>file cf3::\test1\test2\ # rd test3
ALU-1>file cf3::\test1\test2\ # cd ..
ALU-1>file cf3::\test1\ # rd test2
ALU-1>file cf3::\test1\ # cd ..
ALU-1>file cf3::\ # rd test1
ALU-1>file cf3::\ #
Use the following CLI commands to remove a directory without first deleting files or subdirectories:
- CLI syntax:
-
file>
rd file-url rf
Displaying directory and file information
Use the dir command to display a list of files on a file system.
Use the type command to display the contents of a file.
Use the version command to display the version of a 7705 SAR both.tim file.
Use the following CLI commands to display directory and file information:
- CLI syntax:
file>
dir [file-url]
type file-url
version file-url
The following displays an example of the command syntax:
A:ALU-1# file
A:ALU-1>file cf3::\ # dir
Volume in drive cf3: on slot A has no label.
Volume in drive cf3: on slot A is formatted as FAT32.

Command descriptions
Configuration commands
file
Syntax
file
Context
root
Description
This command enters the context to perform file system operations.
When entering the file context, the prompt changes to reflect the present working directory. Navigating the file system with the cd .. command results in a changed prompt.
The exit all command leaves the file system/file operation context and returns to the <ROOT> CLI context. The state of the present working directory is maintained for the CLI session. Entering the file command returns the cursor to the working directory where the exit command was issued.
attrib
Syntax
attrib [+r | -r] file-url
attrib
Context
file
Description
This command sets or clears/resets the read-only attribute for a file in the local file system.
To list all files and their current attributes, enter attrib or attrib x where x is either the filename or a wildcard (*).
When an attrib command is entered to list a specific file or all files in a directory, the file’s attributes are displayed with or without an ‟R” preceding the filename. The ‟R” implies that the +r is set and that the file is read-only. Files without the ‟R” designation imply that the -r is set and that the file is read-write-all. For example:
ALU-1>file cf3:\ # attrib
cf3:\bootlog.txt
cf3:\bof.cfg
cf3:\boot.ldr
cf3:\sr1.cfg
cf3:\test
cf3:\bootlog_prev.txt
R cf3:\BOF.SAV
Parameters
- file-url
the URL for the local file (see URL types and syntax for parameter descriptions)
- +r
sets the read-only attribute on the specified file
- -r
clears/resets the read-only attribute on the specified file
cd
Syntax
cd [file-url]
Context
file
Description
This command displays or changes the current working directory in the local file system.
Parameters
- file-url
the URL for the local file (see URL types and syntax for parameter descriptions)
- <none>
displays the current working directory
- ..
signifies the parent directory. This can be used in place of an actual directory name in a directory-url.
- directory-url
the destination directory
copy
Syntax
copy source-file-url dest-file-url [force]
Context
file
Description
This command copies a file or all files in a directory from a source URL to a destination URL. At least one of the specified URLs should be a local URL. The optional wildcard (*) can be used to copy multiple files that share a common (partial) prefix and/or (partial) suffix.
When a file is copied to a destination with the same filename, the original file is overwritten by the new file specified in the operation. The following prompt appears if the destination file already exists:
‟Overwrite destination file (y/n)?”
For example:
To copy a file named srcfile in a directory called test on cf3: in slot CSM B to a file called destfile in a directory called production on cf3: in slot CSM A, the syntax is:
file cf3:\ # copy cf3-B:/test/srcfile cf3-A:/production/destfile
To FTP a file named 121201.cfg in directory mydir stored on cf3: in slot CSM A to a network FTP server with IP address 192.0.2.255 in a directory called backup with a destination filename of 121201.cfg, the FTP syntax is:
copy cf3-A:/mydir/121201.cfg 192.0.2.255.79/backup/121201.cfg
Parameters
- source-file-url
the location of the source file or directory to be copied (see file-url)
- dest-file-url

shutdown
Syntax
[no] shutdown [active] [standby]
[no] shutdown flash-id
Context
file
Description
This command shuts down (unmounts) the specified CSMs.
Use the no shutdown [active] [standby] command to enable one or both CSMs.
Use the no shutdown flash-id command to enable a compact flash (cf3: on all platforms; cf1: or cf2: on the 7705 SAR-18) on the CSM. The no shutdown command can be issued for a specific slot when no compact flash is present. When a compact flash is installed in the slot, the device is activated upon detection.
In redundant systems, use the no shutdown command on cf3: on both CSMs in order to facilitate synchronization. See the synchronize command in the config>redundancy context.
The shutdown command must be issued before removing a compact flash. If no parameters are specified, the drive referred to by the current working directory shuts down.
LED status indicators – the following states are possible for the compact flash:
Operational: If a compact flash is present in a drive and operational (no shutdown), the respective LED is lit green. The LED flickers when the compact flash is accessed. Do not remove the compact flash during a read/write operation.
State: admin = up, operational = up, equipped
Flash defective: If a compact flash is defective, the respective LED blinks amber to reflect the error condition and a trap is raised.
State: admin = up/down, operational = faulty, equipped = no
Flash drive shut down: When the compact flash drive is shut down and a compact flash is present, the LED is lit amber. In this state, the compact flash can be ejected.
State: admin = down, operational = down, equipped = yes
No compact flash present, drive shut down: If no compact flash is present and the drive is shut down, the LED is unlit.
State: admin = down, operational = down, equipped = no
No compact flash present, drive enabled: If no compact flash is present and the drive is not shut down, the LED is unlit.
State: admin = up, operational = down, equipped = no
Ejecting a compact flash: The compact flash drive should be shut down before ejecting a compact flash. The LED should turn to solid (not blinking) amber. This is the only way to safely remove the compact flash. If a compact flash drive is not shut down before a compact flash is ejected, the LED blinks amber for approximately 5 s before shutting off.
State: admin = down, operational = down, equipped = yes
The shutdown or no shutdown state is not saved in the configuration file. Following a reboot, all compact flash drives are in their default state.
Default
no shutdown – compact flash device is administratively enabled
Parameters
- cflash-id
the compact flash slot ID to be shut down or enabled. If a cflash-id is specified, the drive is shut down or enabled. If no cflash-id is specified, the drive referred to by the current working directory is assumed. If a slot number is not specified, the active CSM is assumed.
- active
all drives on the active CSM are shut down or enabled
- standby
all drives on the standby CSM are shut down or enabled
If both active and standby keywords are specified, all drives on both CSMs are shut down or enabled.
