  NAME

    cd - Changes current working directory

  SYNOPSIS

    cd [directory]

  DESCRIPTION

    The cd command changes the current working directory.  If directory is not
    specified, the value of shell parameter $HOME is used as the new working
    directory.  If directory specifies a complete path starting with /, ., ..,
    directory becomes the new working directory.  If neither case applies, cd
    tries to find the designated directory relative to one of the paths
    specified by the $CDPATH shell variable.  $CDPATH has the same syntax as,
    and similar semantics to, the $PATH shell variable.  The cd command 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; therefore, it is
    recognized and is internal to the shell.

  EXAMPLES

    1.  The following example changes current working directory to the user's
        home directory:

        cd


    2.  The following example changes current working directory to the
        /usr/tmp directory:

        cd /usr/tmp


  DIAGNOSTICS

    Diagnostic messages are issued by the shell.

  EXIT VALUES

    The cd command returns a value of 0 if successful.  If unsuccessful, cd
    returns a value of 1.
