cd

Change the current directory.

• cd [ -sLP ] [ arg ]

  Changes the current directory. In the first form, change the current directory to arg, or to the value of $HOME if arg is not specified. If arg is -, change to the value of $OLDPWD, the previous directory. Otherwise, if a directory named arg is not found in the current directory and arg does not begin with a slash, search each component of the shell parameter cdpath. If no directory is found and the option CDABLE_VARS is set, and a parameter named arg exists whose value begins with a slash, treat its value as the directory. In that case, the parameter is added to the named directory hash table.

• cd [ -sLP ] old new

  Here the cd substitutes the string new for the string old in the name of the current directory, and tries to change to this new directory.

• cd [ -sLP ] {+|-}n

  cd extracts an entry from the directory stack, and changes to that directory.

  Option	Description
  +n	A stack entry by counting from the left of the list shown by the dirs command, starting with zero.
  -n	Counts from the right. If the PUSHD_MINUS option is set, the meanings of + and - in this context are swapped.
  -s	cd refuses to change the current directory if the given pathname contains symlinks.
  -P or CHASE_LINKS	Symbolic links are resolved to their true values.
  -L	Symbolic links are followed regardless of the state of the CHASE_LINKS option.
