File system management commands

	IMPORTANT: ·     Before managing storage media, files, and directories, make sure you know the possible impacts. ·     A file or directory whose name starts with a period (.) is considered a hidden file or directory. Do not give a common file or directory a name that starts with a period. ·     Some system files and directories are hidden.

 

A file name must be specified in one of the file name formats allowed. For more information, see Fundamentals Configuration Guide.

Before you use the copy, delete, fixdisk, format, gunzip, gzip, mkdir, move, rename, rmdir, or undelete command on a USB disk, make sure the disk is not write protected.

You cannot access a storage medium while another user is repairing, formatting, or partitioning the medium.

To access a storage medium after the medium is repaired, formatted, or partitioned, use one of the following methods:

·     Specify the storage medium name for the command. For example, use dir flash:/ to display all files and folders on the flash memory.

·     Use the cd command to change to the storage medium before using the command. For example, use cd flash:/ to change to the root directory of the flash memory, and then use dir to display all files and folders.

The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for features, commands, and parameters might differ in FIPS mode and non-FIPS mode. For more information about FIPS mode, see Security Configuration Guide.

cd

Use cd to change the current working directory.

Syntax

cd { directory | .. }

Views

User view

Predefined user roles

network-admin

Parameters

directory: Specifies the name of the destination directory, in the [drive:/]path format. For more information about how to enter the drive and path arguments, see Fundamentals Configuration Guide. If no drive information is provided, the argument represents a folder or subfolder in the current directory.

..: Specifies the parent directory. If the current working directory is the root directory, an error message appears when you execute the cd .. command. No online help information is available for this keyword.

Examples

# Access the test folder after logging in to the device.

<Sysname> cd test

# Return to the upper directory.

<Sysname> cd ..

# Access the flash root directory of the subordinate member with the member ID 2 after you log in to the master.

<Sysname> cd slot2#flash:/

# Change back to the flash root directory of the master.

<Sysname> cd flash:/

copy

Use copy to copy a file.

Syntax

In non-FIPS mode:

copy fileurl-source fileurl-dest [ source interface interface-type interface-number ]

In FIPS mode:

copy fileurl-source fileurl-dest

Views

User view

Predefined user roles

network-admin

Parameters

fileurl-source: Specifies the name or URL of the file to be copied in non-FIPS mode, and specifies the name of the file to be copied in FIPS mode. If the file resides on an FTP or TFTP server rather than on the device, specify the URL of the file. Whether a URL is case sensitive depends on the server.

fileurl-dest: Specifies the name or URL of the destination file or directory in non-FIPS mode, and specifies the name of the destination file or directory in FIPS mode. To copy the source file to an FTP or TFTP server, specify a URL. If you specify a directory, the device copies the specified file to the directory and saves it with its original file name. Whether a URL is case sensitive depends on the server.

source interface interface-type interface-number: Specifies the source interface used to connect to the server. After you specify the source interface, the device uses the primary IP address of the source interface as the source IP address for outgoing packets. If you do not specify this option, the device uses the outgoing interface as the source interface.

Usage guidelines

In non-FIPS mode, you can use the copy command to perform the following tasks:

·     Copy a local file and save it locally.

·     Copy a local file and save it to an FTP or TFTP server.

·     Copy a file on an FTP or TFTP server and save it locally.

To specify a file or directory, use the following guidelines:

 

Location	Name format	Remarks
On the device	Use the file name guidelines in Fundamentals Configuration Guide.	N/A
On an FTP server	Enter the URL in the format of ftp://FTP username[:password]@server address[:port number]/file path[/file name].	The username and password must be the same as those configured on the FTP server. If the server authenticates users only by the username, you are not required to enter the password. For example, to use the username 1 and password 1 and specify the startup.cfg file in the authorized working directory on FTP server 1.1.1.1, enter ftp://1:[email protected]/startup.cfg. To specify an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, ftp://test:test@[2001::1]:21/test.cfg.
On a TFTP server	Enter the URL in the format of tftp://server address[:port number]/file path[/file name].	For example, to specify the startup.cfg file in the working directory on TFTP server 1.1.1.1, enter the URL tftp://1.1.1.1/startup.cfg. To enter an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, ftp://test:test@[2001::1]:21/test.cfg.

 

In FIPS mode, you can only use the copy command to copy a local file and save it locally.

delete

Use delete to delete a file.

Syntax

delete [ /unreserved ] file-url

Views

User view

Predefined user roles

network-admin

Parameters

/unreserved: Permanently deletes the specified file. If you do not specify this keyword, the command moves the file to the recycle bin.

file-url: Specifies the name of the file to be deleted. Asterisks (*) are acceptable as wildcards. For example, to remove files with the .txt extension in the current directory, enter delete *.txt.

Usage guidelines

Use the delete /unreserved file-url command with caution. You cannot restore a file that was deleted with this command.

The delete file-url command (without /unreserved) moves the specified file to the recycle bin, except in the following two situations, where the file is permanently deleted:

·     The device is running out of storage space.

A file moved to the recycle bin can be restored by using the undelete command.

Do not use the delete command to delete files from the recycle bin. To delete files from the recycle bin, use the reset recycle-bin command.

If you delete two files that have the same name but reside in different directories, both files are retained in the recycle bin. If you successively delete two files that have the same name from the same directory, only the file deleted last is retained in the recycle bin.

Examples

# Remove file 1.cfg from the root directory of the master's storage medium.

<Sysname> delete 1.cfg

Delete flash:/1.cfg?[Y/N]:y

Deleting file flash:/1.cfg...Done.

# Permanently delete file 2.cfg from the root directory of the master's storage medium.

<Sysname> delete /unreserved 2.cfg

The file cannot be restored. Delete flash:/2.cfg?[Y/N]:y

Deleting the file permanently will take a long time. Please wait...

Deleting file flash:/2.cfg...Done.

# Remove file 1.cfg from the root directory of the storage medium on the subordinate member with the member ID 2.

Views

User view

Predefined user roles

network-admin

Parameters

medium-name: Specifies the name of the storage medium to be partitioned. The value varies by device model.

partition-number: Specifies the number of partitions, in the range of 1 to 4.

Usage guidelines

The flash memory cannot be partitioned.

If the partition-number argument is specified, the storage medium is divided into the specified number of partitions. Otherwise, partitioning is performed in an interactive way.

It is normal that the specified partition size and the actual partition size have an error less than 5% of the total memory.

A partition cannot be partitioned.

Before partitioning a USB disk, perform the following tasks:

·     Back up the files in the storage medium. The partition operation clears all data in the medium.

·     If you are partitioning a USB disk, make sure the disk is not write protected. Otherwise, the partition operation will fail, and you must remount or reinstall the disk to restore access to the USB disk.

·     Make sure no other users are accessing the medium. Otherwise, the partition operation fails.

Examples

# Divide the USB disk on the device evenly into three partitions in simple mode.

<Sysname> fdisk usba: 3

Capacity of usba: : 256M bytes

usba: will be divided into the following partitions:

umount

Use umount to unmount a hot swappable storage medium.

Syntax

umount medium-name

Default

A storage medium is automatically mounted and placed in mounted state.

Views

User view

Predefined user roles

network-admin

Parameters

medium-name: Specifies the name of a storage medium. The value varies by device model.

Usage guidelines

Before you remove a mounted storage medium from the system, first unmount it to avoid damaging the medium.

Before you unmount a storage medium, make sure no other users are accessing the medium. Otherwise, the unmount operation fails.

When a storage medium is connected to a lower version system, the system might not be able to automatically recognize the device. In this case, you must first execute the mount command for the storage medium to function correctly.

To avoid file system corruption, do not perform the following tasks while the system is mounting or unmounting a storage medium:

·     Install or remove storage media.

·     perform a master/subordinate switchover.

Examples

# Unmount a USB disk from the master.

<Sysname> umount usba0:

# Unmount a USB disk from the subordinate member with the member ID 2.

<Sysname> umount slot2#usba0:
