v No HOME directory
v No previous directory
v A search for directory failed
v An old-to-new substitution failed
2 An incorrect command-line option
Possible error messages include:
dir bad directory
cd could not locate the target directory. This does not change the working
directory.
Restricted
You are using the restricted version of the shell (for example, by specifying
the –r option for sh). The restricted shell does not allow the cd command.
No HOME directory
You have not assigned a value to the HOME environment variable. Thus,
when you run cd in order to return to your home directory, cd cannot
determine what your home directory is.
No previous directory
You tried the command cd – to return to your previous directory; but there
is no record of your previous directory.
Pattern old not found in dir
You tried a command of the form cd old new. However, the name of the
working directory dir does not contain any string matching the regular
expression old.
POSIX.2, X/Open Portability Guide.
All UNIX systems feature the first form of the command.
The cd old new form of the command is an extension of the POSIX standard.
