One of the problems with working on Linux and Windows OSes has to do with manipulating text files. Lines are separated by a carriage return and a line break character in text files on Windows, whereas on Linux, the separation is done through a single line break character.
Anyone who uses GNU Screen frequently will one day press Ctl-A s (lower-case s) whether purposefully or accidentally. It would seem that there is no way to unlock the screen. Actually, the solution is to press Ctl-A q (lower-case q). You will then be prompted to enter the user’s password to resume using Screen.
During the lifetime of using the computer, I believe everyone will inevitably face the scenario where you will want resize multiple images to a certain size.
In Linux, you can do it will such ease that makes you wonder what you use Windows for.
This effect can be easily done using the command line. Naysayers will probably disclaim the effectiveness of this tip but it really is easy for those who know Linux. All you have to do is to go into the directory where the images are stored and run the following command:
for k in $(ls *.jpg); do convert $k -resize 1024x768 -quality 100 re_$k; done
Frequent Linux users who dual boot their machines with Linux and Windows will inevitably find their GRUB boot loader corrupted at some point in time. This post will help you restore your GRUB boot loader.
In openSUSE 10.3, there is no readily available solution (that I
know of) that lets a user print to PDF. The closest thing there is
to that is a PostScript (PS) file. Fortunately there is a easy way
to convert PS files to PDF. There is a command called
ps2pdf which does exactly that. Its usage is very
straightforward as well:
ps2pdf document.ps document.pdf
How much simpler can that get?
Installing fonts has been somewhat of a neglect in Linux. Although I haven't checked, it seems that recent distributions of SUSE Linux has made it GUI-friendly.
Nevertheless, being a console guy, I believe it's better to know a more reliable way to make things work that is more 'portable' (i.e. work in other distributions as well).
I've always read that installing an operating system, regardless of Windows XP or Linux, on a SD card in the Eee PC is possible. But I haven't got the chance to prove that - until now.
In my previous post, I mentioned that I sometimes have trouble using the mksusebootdisk script make the thumb drive bootable. In a recent endeavour to install openSUSE 10.3 onto the Eee PC again, I encountered the same problem. This time though, I was in a rush for time and simply refused to do the whole process from formatting the file system (till this date I still have not figured out what is the cause of the problem).
To extract the contents of a RPM file, you need the rpm2cpio and the cpio tools. Use them this way:
rpm2cpio name_of_package.rpm | cpio -tv
This will extract the contents of the RPM file.
In the previous post, I described how to create the installation thumb drive. After creating the installation thumb drive, the next step, of course, is to use it to install.
