Shell: Shortcut To Last Command Line Argument

Have you noticed at times that you have been entering same command line parameter over and over again during a certain portion of your shell works?
Have you ever been tired of entering the last command line argument over and over again?

Here's a quick and simple short tip on how to execute shortcut combination keys to make that long-typing parameter words easy to shell redo again.

If you were trying CD into a particular folder like

# cd /home/www/cpanel/com/level2/shared/customers/public_html
bash: cd: /home/www/cpanel/com/level2/shared/customers/public_html: No such file or directory

Now, enter the combination short cut keys for entering the last parameter like so

# mkdir !*
# cd !*
# ls -la !*

The above '!*' would be substituted by /home/www/cpanel/com/level2/shared/customers/public_html when executed by bash.
