cd(1)                    USER COMMANDS                      cd(1)



NAME
     cd - change working directory

SYNOPSIS
     cd [ directory ]

DESCRIPTION
     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 /, ., or ..,  direc-
     tory  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.   cd 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 by and is internal to the shell.
