cd — change working directory

cd [directory]

Since cd affects the current shell execution environment, it is always provided as a shell regular built-in. For more information consult the manual page for the shell in use.

The directory operand is an absolute or relative pathname which becomes the new working directory. The interpretation of a relative pathname by cd depends on the CDPATH environment variable (see below).

The following environment variables affect the execution of cd:

A colon-separated list of pathnames that refer to directories. If the directory operand does not begin with a slash (‘/’) character, and the first component is not dot (‘.’) or dot-dot (‘..’), cd searches for the directory relative to each directory named in the CDPATH variable, in the order listed. The new working directory is set to the first matching directory found. An empty string in place of a directory pathname represents the current directory. If the new working directory was derived from CDPATH, it will be printed to the standard output.
If cd is invoked without arguments and the HOME environment variable exists and contains a directory name, that directory becomes the new working directory.
Set to the previous working directory after a directory change. Not supported by csh(1).
Set to the current working directory.

The cd utility exits 0 on success, and >0 if an error occurs.

csh(1), ksh(1), pwd(1), sh(1), chdir(2)

The cd command is expected to be IEEE Std 1003.2 (“POSIX.2”) compatible.
