cd - Unix, Linux Command
cd - To change directory - change the current working directory to a specific Folder.
cd [Options] [Directory]
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.
