Create a directory AA:mkdir aa, if you create a continuous 5 Directories:mkdir a{ 1..5}, is two . Oh, two points are loops, if mkdir a{1.5} , this is a a{1.5} the directory name. If you create a name for a discontinuous number, it is

Touch is creating a file

.Ln Soft, hard link:ln-s/root/desktop/aa.txt/root/desktop/ . At this time, the desktop has a aa.txt document, but this is a soft connection, I just delete, the document can not open. Then create a hard link:

ln/root/desktop/aa.txt/root/desktop/, that is, no- s, is a hard link. A hard link points to a path where the file is stored on disk, and a soft connection is a path to the actual text you are storing. A hard link cannot be created for a directory, but a soft connection can be, because a soft connection path can be a directory.

package:tar the image below is the format (aa.tar.gz is the name of its own), followed by ". AA" ( . point is the current directory . AA is the current directory. AA )
