CD(1) (Essential Utilities) 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 /, ., .., 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.
