File system management commands

‌

IMPORTANT: ·     Before managing storage media, file systems, directories, and files, make sure you know the possible impact. ·     A file or directory whose name starts with a dot character (.) is a hidden file or directory. To prevent the system from hiding a file or directory, make sure the file or directory name does not start with a dot character. ·     Some system files and directories are hidden. For correct system operation and full functionality, do not modify or delete hidden files or directories. ·     MDC is supported only when the device operates in standalone mode. For more information about standalone mode, see IRF configuration in Virtual Technologies Configuration Guide. For more information about MDC and device models that support MDC, see MDC configuration in Virtual Technologies Configuration Guide.

‌

File system names, directory names, and file names must be compliant with the naming conventions. For more information about the naming conventions and the methods for specifying the names, see file system management in Fundamentals Configuration Guide.

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

You cannot access a storage medium that is being partitioned, or a file system that is being formatted or repaired. To access the file system, wait for the ongoing operation to be completed and then use one of the following methods:

·     Use the absolute path to specify a file or directory. For example, use the dir flash:/ command to display the files and directories in the flash: file system.

·     Use the cd command to change the working directory to the root directory of the file system before accessing a file or directory in the file system. For example, to display the files and directories in the root directory of the flash: file system, perform the following tasks:

a.     Use the cd flash:/ command to change the working directory to the root directory of the file system.

b.     Execute the dir command.

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 working directory.

Syntax

cd { directory | .. }

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

directory: Specifies the destination directory.

..: Specifies the parent directory. If the 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 directory after logging in to the device.

<Sysname> cd test

# Change to the parent directory.

<Sysname> cd ..

copy

Use copy to copy a file.

Syntax

In non-FIPS mode:

copy source-file { dest-file | dest-directory } [ vpn-instance vpn-instance-name ] [ source interface interface-type interface-number ]

In FIPS mode:

copy source-file { dest-file | dest-directory }

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

source-file: 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, TFTP, or HTTP server rather than on the device, specify the URL of the file. Whether a URL is case sensitive depends on the server.

dest-file: Specifies the name or URL for the destination file in non-FIPS mode, and specifies the name for the destination file in FIPS mode. To copy the source file to an FTP, TFTP, or HTTP server, specify a URL. Whether a URL is case sensitive depends on the server.

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

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination FTP, TFTP, or HTTP server belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters. If the server belongs to the public network, do not specify this option.

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

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, TFTP, or HTTP server.

·     Copy a file from an FTP, TFTP, or HTTP 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 the username and password 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 a and password 1 and specify the startup.cfg file in the authorized working directory on the FTP server 1.1.1.1, enter ftp://a:[email protected]/startup.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.
On an HTTP server	Enter the URL in the format of http://[HTTP username[:password]@ ]server address[:port number]/filepath[/file name].	The username and password in the URL must be the same as the username and password configured on the server. If only the username is required for authentication, you do not need to enter the password. If authentication is not required, you do not need to enter the username or password. For example, the startup.cfg file is saved in the authorized directory on the HTTP server at 1.1.1.1. The HTTP account username and password are a and 1, respectively. To copy the file, enter the URL http://a:[email protected]/startup.cfg. If authentication is not required, enter the URL http://1.1.1.1/startup.cfg.

‌

To specify an IPv6 address, enclose the IPv6 address in square brackets ([ ]), for example, ftp://test:test@[2001::1]:21/test.cfg.

delete

Use delete to delete a file.

Syntax

delete [ /unreserved ] file

Views

User view

Predefined user roles

network-admin

mdc-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: 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

	CAUTION: ·     The delete /unreserved file command deletes a file permanently. The file cannot be restored. ·     Using the delete file command (without /unreserved) on the default MDC to delete a file on a non-default MDC permanently deletes that file instead of moving it to the recycle bin.

 

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 from 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 most recently deleted file is retained in the recycle bin.

Examples

# Remove the 1.cfg file from the current directory.

<Sysname> delete 1.cfg

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

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

# Permanently delete the 1.cfg file from the current directory.

<Sysname> delete /unreserved 1.cfg

The file cannot be restored. Delete flash:/1.cfg? [Y/N]:y

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

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

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

/all: Displays all files and directories in the current directory, visible or hidden. If you do not specify this option, only visible files and directories are displayed.

file: Displays a specific file. This argument can use the asterisk (*) as a wildcard. For example, to display files with the .txt extension in the current directory, enter dir *.txt.

directory: Displays a specific directory.

/all-filesystems: Displays files and directories in the root directories of all file systems on the device.

Usage guidelines

If no option is specified, the command displays all visible files and directories in the current directory.

The directory name of the recycle bin is .trash. To display files in the recycle bin, use either of the following methods:

·     Execute the dir /all .trash command.

·     Execute the cd .trash command and then the dir command.

If multiple users perform file operations (for example, creating or deleting files or directories) at the same time, the output for this command might be incorrect.

Examples

# Display information about all files and directories in the current directory.

<Sysname> dir /all

Directory of flash:/

...

# Display files and directories in the root directories of all file systems on the device.

<Sysname> dir /all-filesystems

execute

Use execute to execute a batch file.

Syntax

execute filename

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

filename: Specifies the name of a batch file.

Usage guidelines

A batch file contains a set of commands. Executing a batch file executes the commands in the file one by one.

To execute a batch file on the device, create a batch file on a PC and load the batch file to the device.

As a best practice, try every command on the device to make sure the command line can be executed correctly before adding the command to a batch file. If a command is invalid or a condition for executing the command is not met, the command fails and the system continues to execute the next command.

When executing an interactive command in a batch file, the system uses the default inputs.

Examples

# Execute batch file test.bat.

<Sysname> fdisk usba: 3

[Sysname] execute test.bat

fdisk

Use fdisk to partition a storage medium.

Syntax

fdisk medium [ partition-number ]

Views

User view

Predefined user roles

network-admin

Parameters

medium: Specifies the name of the storage medium to be partitioned.

partition-number: Specifies the number of partitions, in the range of 1 to 4. If you specify this argument, the storage medium is divided evenly into the specified number of partitions. To customize the sizes of partitions, do not provide this argument.

Usage guidelines

This command is supported only on the default MDC.

The flash memory cannot be partitioned. A partition cannot be partitioned.

Before partitioning a storage medium, perform the following tasks:

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

·     Make sure no other users are accessing the medium.

·     Make sure the storage medium to be partitioned is not write protected. If the storage medium is write protected, the operation will fail, and you must remount or reinstall the storage medium to restore access to the storage medium.

After partitioning a storage medium, you must format the partitions to create the file systems before you can access the file systems.

The actual partition size and the specified partition size might have a difference of less than 5% of the storage medium's total size.

To change the sizes of partitions on a storage medium, partition the storage medium again and specify the required sizes for the partitions.

Before removing a partitioned storage medium, you must unmount all file systems on the storage medium.

Generally, file systems on a hot-swappable storage medium are automatically mounted when the storage medium is connected to the device. If the system cannot recognize a file system, however, you must mount the file system before you can access it.

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

·     Reboot, power cycle, or power off the device.

·     Install or remove storage media.

·     Perform a switchover.

To remove a hot-swappable storage medium from the device, you must first unmount all file systems on the storage medium. Removing a mounted hot-swappable storage medium might damage files on the storage medium or even the storage medium.

Examples

# Mount a file system on the USB disk.

Parameters

/force: Deletes all files in the recycle bin without prompting for confirmation. If you do not specify this option, the command prompts you to confirm the deletion operation for each file.

Usage guidelines

CAUTION: The files in a recycle bin can be restored by using the undelete command. If you delete a file from the recycle bin, that file cannot be restored. Before you delete files from a recycle bin, make sure the files are no longer in use.

 

The delete file command only moves a file to the recycle bin. To permanently delete the file, use the reset recycle-bin command to delete the file from the recycle bin.

Examples

# Empty the recycle bin. (In this example there are two files in the recycle bin.)

<Sysname> reset recycle-bin

Clear flash:/a.cfg? [Y/N]:y

Clearing file flash:/a.cfg... Done.

Clear flash:/b.cfg? [Y/N]:y

Parameters

directory: Specifies a directory.

Usage guidelines

CAUTION: To delete a directory, you must first delete all files and subdirectories in the directory permanently or move them to the recycle bin. If you move them to the recycle bin, executing the rmdir command to delete the directory will delete them permanently. Before you use the rmdir command to delete a directory, you must make sure the directory and its files and subdirectories are no longer in use.

 

Examples

# Delete the subtest directory.

<Sysname>rmdir subtest/

Remove directory flash:/test/subtest and the files in the recycle-bin under this directory will be deleted permanently. Continue? [Y/N]:y

Removing directory flash:/test/subtest... Done.

network-admin

mdc-admin

Parameters

gz: Uses gzip to compress the files and directories before archiving them. If you do not specify this keyword, the command archives the files and directories without compressing them.

archive-file dest-file: Specifies the archive file name. If you specified the gz keyword, the extension of the archive file name must be .tar.gz. If you did not specify the gz keyword, the extension of the archive file name must be .tar.

verbose: Displays the names of the successfully archived files and directories. If you do not specify this keyword, the command does not display the names of the successfully archived files and directories.

source { source-file | source-directory }&<1-5>: Specifies the files and directories to be archived. The argument can be a space-separated list of up to five items. Each item can be a file or directory name. The files and directories must be in the current working directory.

Examples

# Archive the 1.cfg and 2.cfg files and the test directory to a.tar.

<Sysname> tar create archive-file a.tar source 1.cfg 2.cfg test

Creating archive flash:/a.tar Done.

# Compress and archive the 1.cfg and 2.cfg files and the test directory to b.tar.gz.

<Sysname> tar create gz archive-file b.tar.gz source 1.cfg 2.cfg test

Creating archive flash:/b.tar.gz Done.

tar extract

Use tar extract to extract files and directories.

Syntax

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

archive-file file: Specifies the archive file name. The extension can be .tar or .tar.gz.

verbose: Displays the names of the successfully extracted files and directories.

screen: Displays the content of the extracted files and directories on the screen. The extracted files are not saved.

to directory: Saves the extracted files and directories to a different directory. The directory argument specifies the directory.

Usage guidelines

IMPORTANT: Before specifying the screen keyword for this command, use the tar list command to identify the types of the archived files. As a best practice, specify the keyword only if all archived files are text files. Displaying the content of an archived non-text file that contains terminal control characters might result in garbled characters and even cause the terminal unable to operate correctly. To use the terminal again, you must close the current connection and log in to the device again.

 

If you do not specify the screen keyword or the to directory option, the command saves the extracted files and directories to the working directory.

The command saves the extracted files and directories by using their original names. If a file or directory that has the same name as an extracted file or directory already exists in the destination directory, the file or directory is overwritten.

Examples

# Extract files and directories from archive file a.tar.

<Sysname> tar extract archive-file a.tar

Extracting archive flash:/a.tar Done.

# Extract files and directories from archive file a.tar, and display the names of the successfully extracted files and directories.

Parameters

filesystem: Specifies the name of a file system.

Usage guidelines

File systems on a storage medium are automatically mounted when the storage medium is connected to the device. To remove a hot-swappable storage medium from the device, you must first unmount all file systems on the storage medium. Removing a mounted hot-swappable storage medium might damage files on the storage medium or even the storage medium.

You can unmount a file system only when no other users are accessing the file system.

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

·     Reboot, power cycle, or power off the device.

·     Install, remove, or access storage media.

·     Install or remove MPUs.

·     Perform a switchover.

·     Create, delete, start, or stop an MDC.
