File system management commands

IMPORTANT

IMPORTANT:

·     Before managing storage media, file systems, files, and directories, make sure you know the possible impacts.

·     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.

 

File system names, directory names, or file names must be compliant with the naming conventions. For more information about the naming conventions   and the methods for specifying the names, 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 file system that is being formatted or repaired. To access a file system after it is formatted or repaired, 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 file system on the flash memory.

·     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 file system on the flash memory, 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.

cd

Use cd to change the working directory.

Syntax

cd { directory | .. }

Views

User view

Predefined user roles

network-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

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

Views

User view

Predefined user roles

network-admin

Parameters

source-file: Specifies the name or URL of the file to be copied. 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.

{ dest-file | dest-directory }: Specifies the name or URL of the destination file or directory. 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

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://1:1@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.

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, tftp://[2001::1]:21/test.cfg.

 

Examples

# Copy the test.cfg file in the current directory and save it to the current directory as testbackup.cfg.

<Sysname> copy test.cfg testbackup.cfg

Copy flash:/test.cfg to flash:/testbackup.cfg? [Y/N]:y

Copying file flash:/test.cfg to flash:/testbackup.cfg...Done.

delete

Use delete to delete a file.

Syntax

delete [ /unreserved ] file

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: 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 command with caution. You cannot restore a file that was deleted with this command.

The delete file command (without /unreserved) moves the specified file to the recycle bin if the file system has sufficient storage space. If the file system is running out of storage space, the command permanently deletes the file.

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 file 1.cfg from the current directory.

<Sysname> delete 1.cfg

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

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

# Permanently delete file 1.cfg 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.

# (IRF-capable devices.) Remove file 1.cfg from the current directory.
