NAME
     cd, chdir, pushd, popd, dirs - change working directory

SYNOPSIS

     cd [ dir ]
     chdir [ dir ]
     pushd [ +n | dir]
     popd [ +n ]
     dirs [ -l ]

DESCRIPTION
     If dir is not specified, the C shell built-in  cd  uses  the
     value  of shell parameter HOME as the new working directory.
     If dir specifies a complete path starting with ` / ', ` . ',
     or  `  .. ', dir becomes the new working directory.  If nei-
     ther 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 seman-
     tics  to,  the  PATH  shell  variable.  cd must have execute
     (search) permission  in  dir.   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 recog-
     nized  by  and  is  internal  to  the C-shell.  (See pwd(1),
     sh(1), and chdir(2)).

     chdir changes the shell's  working  directory  to  directory
     dir.   If no argument is given, change to the home directory
     of the user.  If dir is a relative pathname not found in the
     current  directory, check for it in those directories listed
     in the cdpath variable.  If dir is the name of a shell vari-
     able  whose  value  starts with a /, change to the directory
     named by that value.

     pushd will push a directory onto the directory stack.   With
     no arguments, exchange the top two elements.

     +n   Rotate the n'th entry to the top of the stack and cd to
          it.

     dir  Push the current working directory onto the  stack  and
          change to dir.

     +n   Discard the n'th entry in the stack.

     dirs will print the directory  stack,  most  recent  to  the
     left;  the  first  directory shown is the current directory.
     With the -l argument, produce an unabbreviated printout; use
     of the ~ notation is suppressed.

for more information, use the 'man cd' command.
