Command-line calculations using bc

Post date: November 29, 2006, 01:11 Category: Software Views: 4581 Comments
Tutorial quote: If like me, you do most of your work from the command-line, using vim to edit files, mutt for e-mails, cd/ls/mv/find/etc instead of a file manager, then you may get annoyed by having to fire up a GUI calculator to make (what may sometimes be) a single calculation.

One useful feature of calculating on the command-line is that you can see what you've typed. For instance, sometimes when I'm entering a long, complex calculation on a calculator (either the GUI or the solid, hold-in-your-hand type), I sometimes forget if I've actually typed in all those numbers or made the calculations in the right order.

Byzanz - free opensource Desktop Recording (command-line) tool

Post date: October 11, 2008, 22:10 Category: Desktop Views: 3493 Comments
Tutorial quote: Byzanz is a free opensource GNOME based Command-Line utility to capture desktop recording software for linux. This should probably be the coolest command-line utility that I have seen in recent days. Byzanz records your desktop session to an animated GIF. You can record your entire screen, a single window, an arbitrary region or even follow the cursor. Given that it is only a GIF format makes it even more an interesting proposition as the file size is going to be very small.

Tutorial quote: DVD writers have become so common these days that there is hardly any difference between the price of a CD-writer drive and a DVD-writer drive. So I'm assuming that almost everyone would be buying a DVD writer drive these days. Below are a few tips for newbies on how to burn DVDs on a Debian box using the command line. Other GUI tools like k3b, nautilus burner, etc exists but its always fun to know how to do that stuff from command line.

It can also be used for copying files, as an alternative to sftp/scp, thus avoiding password prompts when X11 forwarding has already been setup. xclip reads from Standard Input or from one or more files and copy it to the X11 clipboard making it available to the X applications. xclip can also print the content of the current X clipboard onto the standard output or to a file.

Post date: November 5, 2006, 21:11 Category: System Views: 4234 Comments
Tutorial quote: This guide describes how to install and use xen-tools, xen-shell, and Argo on a Debian system. All three packages provide useful tools for the administration of virtual Xen machines. Xen-tools is a collection of Perl scripts that allow you to easily create, update, and delete Xen guest domains.

And with Argo, you can control Xen domains through a web interface or through a menu on the command line.

Mepis + apt = Working On Easy Street

Post date: April 13, 2005, 19:04 Category: System Views: 5674 Comments
Tutorial quote: My reasoning for combining the traditional Debian apt command with Mepis was speed and efficiency. Also, in the fine tradition of open source, I could choose to use the command line instead of the Kpackage or Mepis System Center package management screen. This is a good way to learn about Debian systems that builds confidence for new users right off the bat.

Let's see how apt works with Mepis.
