Before you can copy or move files into a directory, that directory
must exist, and this means you or some super friend has made that
directory with the command:
| % mkdir dirname | Make directory dirname. |
And since she who giveth may also taketh,
| % rmdir dirname Remove directory dirname. |
These commands are fail safe; Unix won't let you remove a directory if there are any files in it, or let you make a directory with the a name which already exists.
As you can probably guess by now, the full path name may also be used
to make a new directory (or remove an old one) anywhere in your
workspace. So to make the directory lib, bohr could enter one
of the following:
| % mkdir /user/bohr/lib | Make lib from anywhere. |
| % cp * /user/bohr/lib | Copy all files to lib. |
| % ls /user/bohr/lib | List files in directory. |
| file1 file2 file3 | |
| % cd | Go to bohr's own home directory. |
| % mkdir lib | Make lib from bohr's home directory. |
| mkdir: src: File exists | mkdir returns an error message. |
| % rmdir /user/bohr/lib | Remove lib from anywhere. |
| rmdir: src not empty | Can only remove empty directory. |
