NAME
cd - change working directory SYNOPSIS
cd directory DESCRIPTION
Directory becomes the new working directory. The process must have execute (search) permission in directory. Because a new process is created to execute each command, cd would be ineffective if it were written as a normal command. It is therefore recognized and executed by the shells. In csh(1) you may specify a list of directories in which directory is to be sought as a subdirec- tory if it is not a subdirectory of the current directory; see the description of the cdpath variable in csh(1).
