</div></div>A fellow Slackware users... howdy. :-)<br>
<br>
Here's some thought on "sudo" off top of my head (in case you don't get<br>
straight root access):<br>
- sudo -i<br>
- sudo -e --> edit file<br>
- visudo --> edit /etc/sudoers. I add "NOPASSWD:" to avoid<br>
typing password.<br>
- vipw [-s]<br>
- vigr [-s]<br>
