Hiya everyone,<br><br>I just thought i'd drop a quick email to let you know about some awesome commands I picked up on my RH course.<br><br>Firstly lets start simple: mtr<br><br>You've done traceroute and ping, but this is both in one tool, and on steroids. For example try mtr <a href="http://www.google.com">www.google.com</a>. This is awesome as it shows firstly the route and also all your network choke points are, and how bad they are. Its in RH, Centos, Fedora and available for most distros.<br>
<br>Secondly, watch.<br><br>How often have you done a large cp command and waited, and waited. If you do it, set up another console and do watch df -h. It will basically repeat df -h every two seconds, so you can see what is happening with disk space. Basically watch will allow you to automate a command! You can change the time interval.<br>
<br>Thirdly screen.<br><br>Rather than having loads of terminal windows open, use screen. It will allow you to run many consoles within one window. Shortcut keys allow you to move between the screens.<br><br>Fouthly, partprobe<br>
<br>You know when you create a new disk or partitions and you have to reboot, well this funky app, run after using fdisk, will re read all the new partitions and make them all available. Saves a reboot.<br><br>Old command, new command.<br>
<br>lsof is so old, use fuser. It does the same thing but is more useful ;)<br><br>If I think of any others, I'll let you know!<br><br>Regards<br><br>Stuart<br><br>
