In Linux what are three commands you can use to create a subdirectory?
1. The most straightforward way to create a create a
subdirectory in the current directory is
mkdir name
where name is the name of the new directory.
2. Another way is to move a directory and its descendants from
somewhere else:
mv path name
where path is an absolute or relative pathname for an existing
directory hierarchy, and name is the directory name it will be
given in the current directory.
3. Various utilities for unpacking archives may create
directories as they execute; for example cpio, tar, unzip etc.
