Managing the file system
This chapter describes how to manage the device's file system, including the storage media, directories, and files.
Your device might have a Flash, a CF card, or both, depending on your device model. For more information, see About the H3C Access Controllers Configuration Guides.
File name formats
When you specify a file, enter the file name in one of the formats shown in Table 1. When you specify a directory, enter the directory in one of the formats that contains the path argument.
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 cfa0. 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 |
cfa0:/test/a.cfg indicates a file named a.cfg in the test folder in the root directory of the CF card. |
Managing files
|
CAUTION: To avoid file system corruption, do not install or remove storage media or perform active/standby switchover while the system is processing a file operation. |
You can display directory and file information, display file contents, rename, copy, move, remove, restore, and delete files, and calculate file digests.
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 [ | { begin | exclude | include } regular-expression ] |
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 |
Calculating the digest of a file
The digest of a file can be used to verify the file integrity. For example, you can calculate the digest of a software image file and compare it with that provided on the H3C website to verify whether the file has been tampered with.
Perform this task in user view.
Task |
Command |
Calculate the digest of a file. |
crypto-digest sha256 file-url |
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.
Perform this task in user view.
Task |
Command |
Remove a directory. |
rmdir directory |
Managing storage media
|
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 |
Remarks |
Repair a storage medium. |
fixdisk device |
N/A |
Format a storage medium. |
format device [ FAT16 | FAT32 ] |
FAT16 and FAT32 are not applicable to the Flash memory. |
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 met, 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 avoid problems, 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. |
