cd(1)cd(1)NAMEcd - change working directory
SYNOPSIScd [ 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 /, ., .., 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.
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 and is internal to the shell.
