ls -alGlobing: Globing is the term for Unix-style "wildcards". These are handled completely differently than they are in Windows/DOS. In Windows, the program being executed is responsible for expanding wildcard characters. In Unix, the shell expands the filename specified. The Unix globing characters are:
? Matches any one character in a filename. * Matches any character or characters in a filename. [ ] Matches a character within the brackets. - A hyphen used within [ ] denotes a range of characters. ~ A tilda at the beginning of a filename expands to be the user's home directory.Note the absence of a "." period character. Unix does not have the equivalent of Windows-style filename extensions. A Starter Set of Commands Here are a few shell commands to start with.
ls List files. This is sort of like DIR in DOS. cd Change directory. mkdir Make directory. rmdir Remove directory. cat Concatenate file(s) to standard output. Can be used to display file contents.Jump in and get your feet wet. Next, I'll revisit this topic and expand on it a bit.
