Emergency shell commands

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.

Unless otherwise stated, a file or directory name argument in this document must contain the file system name and cannot contain file system location information. The path information can contain multiple levels of directories, each of which can have 1 to 255 characters. The file name alone (without the path information) can have 1 to 255 characters. The entire argument can have 1 to 511 characters.

If the device has a flash memory and a CF card, you can access the flash memory and the CF card in emergency shell mode. Examples in this chapter use the flash memory. A different storage medium might be used on your device.

copy

Syntax

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

source-file: Specifies the file to be copied.

dest-file: Specifies the destination file.

dest-directory: Specifies the destination directory. The system uses the name of the source file as the name for the destination file.

Usage guidelines

# Copy the test.cfg file. Save the copy to testbackup.cfg.

<boot> copy flash:/test.cfg flash:/testbackup.cfg

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

Start to copy flash:/test.cfg to flash:/testbackup.cfg...Done.

# Copy the test.cfg file and save the copy to testbackup.cfg. Overwrite the existing file that has the same name as the destination file.

<boot> copy flash:/test.cfg flash:/testbackup.cfg

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