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 given, changes the shell's working directory todirectory. If not, changes to HOME (shell variable).

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)
