</div>The sudo-bang-bang thing is cool. I sometimes hit the up arrow, home,<br>
then type sudo in front of the prior command.<br>
<br></blockquote><div><br>That is what I did before I learned about the shell's bang-bang... operator, I guess is what it would be classified as. You can use "sudo !-1" as well, but that's not as fun as "sudo !!". :)<br>
<br>The ! character, according to the bash man page (which, if you've never read or looked at, is the **one** man page that you should **never** attempt to print!) "[starts] a history substitution", with exceptions. You can find the information in the "Event Designators" section of the bash man page. <br>
