CLKF Course - Reuse the Arguments from the Previous Command Line

From: http://www.linuxtrainingacademy.com/

To reuse the arguments from the previous command line on the current command line, use "!*". The arguments are considered anything on the command line except for the first item. Since the first item is almost always a command, then everything following is an argument.

Using this shortcut can be helpful in a couple of different situations. First, it's great when you are working on a list or series of items such as files or directories. It also proves to be useful when you accidentally mistype a command. Instead of typing the entire command line over again, simply correct your typing mistake and follow it with "!*".

The following is an example of working with a series of items.

$ ls file1 file2 file3 file1 file2 file3 $ vi !* $ mv !* /tmp/

Yet another example dealing with a list of items. In this case, directories.

$ mkdir one two three $ chmod 700 !* $ ls -l drwx------ 2 jason users 4096 Jul 5 18:44 one drwx------ 2 jason users 4096 Jul 5 18:44 three drwx------ 2 jason users 4096 Jul 5 18:44 two

Here are examples of correcting command typos.
