Cd command is also used to move a directory from one location to other. You can use cd command to move to any directory by writing the location specifically. For ex. cd/abc/def/new-folder. Make sure Linux is a case sensitive OS , your spelling must be correct & exact letters are used. If any letter is written wrong then error message will be displayed.
