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.
