cd

Change Directory - change the current working directory to a specific Folder.

Syntax 
      cd [Options] [Directory]

Key
    -P    Do not follow symbolic links
    -L    Follow symbolic links (default)

If directory is not given, the value of the HOME shell variable is used.

If the shell variable CDPATH exists, it is used as a search path.
If directory begins with a slash, CDPATH is not used.

If directory is `-', this will change to the previous directory location (equivalent to $OLDPWD ).

The return status is zero if the directory is successfully changed, non-zero otherwise.

Examples

Move to the sybase folder
$ cd /usr/local/sybase
$ pwd
/usr/local/sybase

Change to another folder
$ cd /var/log
$ pwd
/var/log

Quickly get back
$ cd -
$ pwd
/usr/local/sybase

move up one folder
$ cd ..
$ pwd
/usr/local/

$ cd (Back to your home folder)
