Once a directory system exists, you need to know how to get from
one directory to another, thereby changing your current working
directory. This is done using the
cd(C)
(change directory) command. As an argument to the command, you
specify the directory you want to change to, as follows:
cd directory
For example, if your current directory is /u/johnd, you can to change to a directory called /u/workfiles/projects by specifying its absolute pathname, as follows:
$ cd /u/workfiles/projectsYou can also change to the directory by specifying its relative pathname, as follows:
$ cd ../workfiles/projectsNote that you must have execute permission on a directory before you can change to it. See ``Access control for files and directories''. See ``Returning to your home directory'' for details of a special usage of cd.
