Description

This command changes the current working directory that is used by the UEFI Shell environment.

If a file system mapping is specified, then the current working directory is changed for that device.

Otherwise, the current working directory is changed for the current device.

If path is not present, then the current working directory (including file system mapping) is displayed

to standard output.

Table 4 (page 23) describes the conventions that are used to refer to the directory, its parent, and

the root directory in the UEFI Shell environment.

Table 4 Directory name conventions

Refers to the...Convention

Current directory..

Parent of the current directory.. .

Root of the current file system.\

The current working directory is maintained in the environment variable %cwd%.

Examples

To change the current file system to the mapped fs0 file system:

Shell> fs0:

To change the current directory to subdirectory efi:

fs0:\> cd efi

To change the current directory to the parent directory (fs0:\):

fs0:\efi\> cd ..

To change the current directory to fs0:\efi\tools:

fs0:\> cd efi\tools

To change the current directory to the root of the current fs (fs0):

fs0:\efi\tools\> cd \

fs0:\>

NOTE: Changing volumes with cd does not work. For example:

fs0:\efi\tools\> cd fs1:\

First enter fs1:, then cd to the directory you want.

To move between volumes and maintain the current path:

fs0:\> cd \efi\tools

fs0:\efi\tools\> fs1:

fs1:\> cd tmp

fs1:\tmp> cp fs0:*.* .

This copies all of files in fs0:\efi\tools into the fs1:\tmp directory.

cls

Clears the standard output and optionally changes the background color.

Syntax

cls [color]

Options
