With no arguments, change to home directory of user. Otherwise, change working directory to dir . If dir is a relative pathname but is not in the current directory, then the CDPATH variable is searched. The last two command forms are specific to the Korn shell, where - stands for the previous directory. The third syntax modifies the current directory name by replacing string old with new , then switches to the resulting directory.

Example

$ 

pwd

 /usr/spool/cron $ 

cd cron uucp

	# cd prints the new directory /usr/spool/uucp
