Overview

This chapter describes how to manage the device's file system, including the storage media, directories, and files.

File name formats

When you specify a file, enter the file name in one of the formats shown in Table 1. The similar rules apply to directory names.

Table 1 File name formats

Format	Description	Length	Example
file-name	Specifies a file in the current working directory.	1 to 91 characters	a.cfg indicates a file named a.cfg in the current working directory.
path/file-name	Specifies a file in a specific folder in the current working directory. The path argument represents the path to the file. If the file is in a single-level folder, specify the folder name for the argument. If the file is in a nested folder, separate each folder name by a forward slash (/).	1 to 135 characters	test/a.cfg indicates a file named a.cfg in the test folder in the current working directory.
drive:/[path]/file-name	Specifies a file in a specific storage medium on the device. The drive argument represents the storage medium name, typically flash or cf. If the device has only one storage medium, you do not need to specify the storage medium. If the device has multiple storage media, you must provide the storage medium name.	1 to 135 characters	flash:/test/a.cfg indicates a file named a.cfg in the test folder of the Flash root directory.

 

Managing files

You can display directory and file information, display file contents, and rename, copy, move, remove, restore, and delete files.

The copy operation enables you to create a file. You can also create a file by performing the download operation or using the save command.

Displaying file information

Perform this task in user view.

 

Task	Command
Display file or directory information.	dir [ /all ] [ file-url | /all-filesystems ]

 

Displaying the contents of a file

Perform this task in user view.

 

Task	Command	Remarks
Display the contents of a file.	more file-url	Only text files can be displayed.

 

Renaming a file

Perform this task in user view.

 

Task	Command
Rename a file.	rename fileurl-source fileurl-dest

 

Copying a file

Perform this task in user view.

 

Task	Command
Copy a file.	copy fileurl-source fileurl-dest

 

Moving a file

Perform this task in user view.

 

Task	Command
Move a file.	move fileurl-source fileurl-dest

 

Deleting/restoring a file

You can delete a file permanently or move it to the recycle bin. A file moved to the recycle bin can be restored, but a permanently deleted file cannot.

A file in the recycle bin occupies storage space. To release the occupied space, execute the reset recycle-bin command in the directory that holds the file. To save storage space, periodically empty the recycle bin with the reset recycle-bin command.

Perform the following tasks in user view:

 

Task	Command
Delete a file by moving it to the recycle bin.	delete file-url
Restore a file from the recycle bin.	undelete file-url
Delete a file permanently.	delete /unreserved file-url

 

Emptying the recycle bin

 

Step	Command	Remarks
1.       Enter the original working directory of the file to be deleted in user view.	cd { directory | .. | / }	Skip this step if the original directory of the file is the current working directory.
2.       Empty the recycle bin.	reset recycle-bin [ /force ]	N/A

 

Managing directories

You can create or remove a directory, display or change the current working directory, and display a specific directory.

Displaying directory information

Perform this task in user view.

 

Task	Command
Display directory or file information.	dir [ /all ] [ file-url | /all-filesystems ]

 

Displaying the current working directory

Perform this task in user view.

 

Task	Command
Display the current working directory.	pwd

 

Changing the current working directory

Perform this task in user view.

 

Task	Command
Change the current working directory.	cd { directory | .. | / }

 

Creating a directory

Perform this task in user view.

 

Task	Command
Create a directory.	mkdir directory

 

Removing a directory

To remove a directory, you must delete all files and subdirectories in this directory. To delete a file, use the delete command. To delete a subdirectory, use the rmdir command.

Removing a directory permanently deletes all its files in the recycle bin, if any.

Perform this task in user view.

 

Task	Command
Remove a directory.	rmdir directory

 

Managing storage medium space

 

	CAUTION: After a storage medium is formatted, all files on it are erased and cannot be restored. If a startup configuration file exists on the storage medium, formatting the storage medium results in loss of the startup configuration file.

 

If part of a storage medium is inaccessible, use the fixdisk command to examine the medium for any damage and repair the medium.

To manage the space of a storage medium, perform one of the following tasks in user view:

 

Task	Command
Repair a storage medium.	fixdisk device
Format a storage medium.	format device

 

Performing batch operations

A batch file comprises a set of executable commands. Executing a batch file is the same as executing the commands one by one. However, execution of a batch file does not guarantee successful execution of every command in the batch file. If a command has error settings or the conditions for executing the command are not satisfied, the system skips this command.

You can edit a batch file on your PC, and then upload or download it to the device. If the extension of the file is not .bat, use the rename command to change it to .bat.

To execute a batch file:

 

Step	Command
1.       Enter system view.	system-view
2.       Execute a batch file.	execute filename

 

Setting the file system operation mode

The file systems support the following operation modes:

·          alert—The system warns you about operations that might cause problems such as file corruption and data loss. To prevent incorrect operations, use the alert mode.

·          quiet—The system does not prompt for any operation confirmation.

To set the file system operation mode:

 

Step	Command	Remarks
1.       Enter system view.	system-view	N/A
2.       Set the file system operation mode.	file prompt { alert | quiet }	Optional. The default is alert.
