2 1.1 File System Note: The limitations on the names of directories and files on switch are as follows: It is recommended that the name of a directory or file should not contain more than 56 characters; otherwise you will not be able to delete such a directory or file, even though the system supports directory or file names containing more than 64 characters. The total number of characters including device, single directory and file names can be up to 136 characters long cd cd directory directory: Destination directory. By default, the directory is the active path configured by the user when the system starts. Use the cd command to change the current path on the Switch. The default directory is the one set up at startup.. # Change the current directory of the switch to flash. <H3C> cd flash: <H3C> pwd flash: 1-1

3 1.1.2 copy copy fileurl-source fileurl-dest fileurl-source: Source file name. fileurl-dest: Destination file name. Use the copy command to copy a file. You can use this command to copy a file from current directory to another directory, or vise versa. Where, the source filename must be the name of a file that has already existed in the specified directory, and the destination filename can be changed as required. When the destination filename is the same as that of an existing file, the system will ask whether to overwrite it. # Copy file flash:/manuinfo.txt and saves it as flash:/manuinfo.bak. <H3C> copy flash:/manuinfo.txt flash:/manuinfo.bak Copy flash:/manuinfo.txt to flash:/manuinfo.bak?[y/n]:y 100% complete Copy file flash:/manuinfo.txt to flash:/manuinfo.bak...done delete delete [ /unreserved ] file-url /unreserved: Delete the file completely. file-url: Path and name of the file you want to delete. 1-2

4 Use the delete command to cancel a specified file from the storage device of the switch. This command supports wildcard characters. The deleted files are kept in the recycle bin and will not be displayed when you use the dir command. However you can use the dir /all command to display them. The files deleted by the delete command can be recovered by the undelete command or deleted permanently from the recycle bin by the reset recycle-bin command. Note that, if two files with the same name in a directory are deleted, only the latest deleted file will be kept in the recycle bin. # Delete file flash:/manuinfo.bak. <H3C> delete flash:/manuinfo.bak Delete flash:/manuinfo.bak?[y/n]:y Deleted file flash:/manuinfo.bak dir dir [ /all ] [ file-url ] /all: Display all the files (including the deleted ones). file-url: File or directory name to be displayed. The file-url argument supports the wild card *. For example, using dir *.txt will display all the files with the extension txt in the current directory. Use the dir command to view the information about the specified file or directory in the storage device of the switch. # Display information about file flash:/test/test.txt <H3C> dir flash:/test/test.txt Directory of flash:/test/ 0 -rw- 1 noone nogroup 971 Sep :28:52 test.txt 1-3

5 7747 KB total (4850 KB free) # Display the information about all the files (including the deleted ones) in the flash:/test/ directory. <H3C> dir /all flash:/test/ Directory of flash:/test/ -rwxrwxrwx 1 noone nogroup 971 Sep :28:52 test.txt 1 -rw- 4 Apr :13:47 [snmpboots] KB total (2182 KB free) The files that have already been deleted and kept in the recycle bin are displayed with the square brackets [ ]. # Display the information about all the files (including the deleted ones) in the flash:/test/ directory whose names start with the t character. <H3C> dir /all flash:/test/t* Directory of flash:/test/ 0 -rw- 1 noone nogroup 971 Sep :28:52 test.txt 7747 KB total (4850 KB free) execute execute filename System view filename: Name of the batch file, ranging from 1 to 256. Use the execute command to execute the specified batch file. The batch command executes the command lines in the batch file one by one. There should be no invisible character in the batch file. If invisible characters are found, the batch command will quit the current execution without back off operation. The batch command does not guarantee the execution of each command, nor does it perform hot backup itself. The forms and contents of the commands are not restricted in the batch file. # Execute the batch file test.bat in the directory flash:/. <H3C> system-view 1-4

6 System : return to User with Ctrl+Z. [H3C] execute test.bat fdisk fdisk device device: Name of the device to be partitioned. Now, the Switch only supports the partitioning of CF cards. A device is automatically divided into two partitions with equal size: Partition 1 is named cf: and Partition 2 is named log:. Use the fdisk command to partition a device. Caution: Do not save the system startup file and configuration file in Partition 2. The system cannot be started from Partition 2. # Partition the CF card on the SRPU. <H3C> fdisk cf: All data on the device will be lost, continue? [Y/N]: y Partition 1: KB Partition 2: KB Done. Note: The displayed information of the fdisk command varies with the CF card. 1-5

7 1.1.7 file prompt file prompt { alert quiet } System view alert: Performs interactive confirmation on dangerous file operations. quiet: Does not prompt for the file operations. Use the file prompt command to change the prompt modes of the file operation on the switch. By default, the prompt mode of the file operation is alert, which performs interactive confirmation on dangerous file operations. If the prompt mode is set as quiet, that is, no prompt for file operations, some non-recoverable operations may lead to system damage. # Configure the prompt mode of file operation as quiet. <H3C> system-view System : return to User with Ctrl+Z. [H3C] file prompt quiet fixdisk fixdisk device device: Device name. Use the fixdisk command to restore the space of a storage device. Some of the space of a storage device may be unavailable for some reason (such as abnormal operations). In this case, you can use this command to restore the space. 1-6

8 Currently, the switch does not support this command on the compact flash (CF) card. # Restore the space of the storage device Flash. <H3C> fixdisk flash: format format filesystem filesystem: Device name. Use the format command to format the storage device. Format operation will cause non-recoverable loss of all the files on the device. Specially, configuration files will be lost after formatting the flash memory. # Format Flash. <H3C> format flash: All data on flash: will be lost, proceed with format? [Y/N]:y \ Format flash: completed mkdir mkdir directory directory: Directory name. 1-7

9 Use the mkdir command to create directory in the specified directory on the storage device. The directory to be created cannot have the same name as that of other directory or file in the specified directory. # Create the directory dd. <H3C> mkdir dd Created dir flash:/dd more more file-url file-url: File name. Use the more command to view the contents of a specific file. At present, the file system can display files in text format. This command can be used to display the contents of the files with.txt suffix or.cfg (configuration) suffix. # Display the contents of file test.txt. <H3C> more test.txt AppWizard has created this test application for you. This file contains a summary of what you will find in each of the files that make up your test application. Test.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. 1-8

10 move move fileurl-source fileurl-dest fileurl-source: Source file name. fileurl-dest: Destination file name. Use the move command to move files. When the destination filename is the same as that of an existing file, the system will ask whether to overwrite it. # Move flash:/test/sample.txt to flash:/sample.txt. <H3C> move flash:/test/sample.txt flash:/sample.txt Move flash:/test/sample.txt to flash:/sample.txt?[y/n]:y Moved file flash:/test/sample.txt to flash:/sample.txt. Note: The switch has the following limitations on directory name and filename: The maximum length of a directory name or filename is 56 characters. The maximum length of a full-path filename (including the device name, directory name, and filename) is 136 characters. The move command can be successfully executed only when the source file and the destination file are on the same device pwd pwd 1-9

11 None Use the pwd command to view the current path. Error may occur if the path to be displayed does not exist. # Display the current path. <H3C> pwd flash: rename rename fileurl-source fileurl-dest fileurl-source: Source file name. fileurl-dest: Destination file name. Use the rename command to rename a file. If the destination file name is identical with that of an already existent directory or file, the rename operation fails and the system prompts that name has already been used or the file is being used. # Rename the file sample.txt to sample.bak. <H3C> rename sample.txt sample.bak Rename flash:/sample.txt to flash:/sample.bak?[y/n]:y Renamed file flash:/sample.txt to flash:/sample.bak reset recycle-bin reset recycle-bin [ file-url ] 1-10

12 file-url: Name of the file to be deleted. Use the reset recycle-bin command to permanently delete files from the recycle bin. The file-url supports the wildcard character "*.The delete command only puts the file into the recycle bin, but reset recycle-bin command will delete this file permanently. # Delete the file from the recycle bin. <H3C> reset recycle-bin flash:/ config.vrrp Squeeze flash:/ vrpcgf.vrrp? [Y/N]:y Clear files from flash may take a long time.please wait Done. Cleared file flash:/config.vrrp rmdir rmdir directory directory: Directory name. Use the rmdir command to cancel a directory. The directory to be deleted must be empty, that is, all the files under the directory should be removed first. Note: When you delete a directory using the rmdir command, the files that belonged to this directory, but are now in the Recycle Bin, will also be deleted. 1-11

13 # Delete the directory test. <H3C> rmdir test Rmdir flash:/test?[y/n]:y Removed directory flash:/test umount umount device device: Device name. Now, it can only be CF. Use the umount command to remove the CF card from the file system. # Remove the CF card from the file system. <H3C> umount cf: Umount cf: succeed undelete undelete file-url file-url: Name of the file to be recovered. Use the undelete command to recover the file that has not been deleted completely. The file name to be recovered cannot be the same as an existing directory name. If the destination file name is the same as an existing file name, the system will ask you whether to overwrite it. 1-12

14 # Recover the deleted file sample.bak. <H3C> undelete sample.bak Undelete flash:/sample.bak?[y/n]:y Undeleted file flash:/sample.bak. 1-13
