BING comes up with a beautiful background everyday. I thought why not set this background as my desktop wallpaper. But it would be a cumbersome task to set it manually. So I searched (Googled, BINGed) for some script which will do this for me. I found BING Downloader which does this task on Windows. I could not find any such script for GNOME. So, I thought of writing one.
I wrote a script which when executed automatically sets the GNOME wallpaper as BING background of the day. This is a PHP script. To execute this script you need to have php installed on your system. You can install php in Ubuntu as
sudo apt-get install php5 php5-cli
Linux man pages are the most important resource for a Linux freak. By default man pages are formatted using the ‘less’ utility. ‘less’ shows the man pages in black & white, something like this :
If you use ‘most’ utility to format man pages, you will get a properly colour-formatted man pages. Take a look at man pages configured on my system :
Do you like this one ?? Read on how to configure ‘most’ as your man pages viewer.
Step 1: Install the package ‘most’
$ sudo aptitude install most
Step 2: Configure ‘most’ as your man page viewer using update-alternatives :
$ sudo update-alternatives --config pager
Enter the number corresponding to /usr/bin/most , here in this screenshot its 5.
Yeah, its done. Nothing more to do !!
Let me know if you find any difficulty doing this.
P.S: This can be done in Fedora as well as other linux also. In Fedora I guess you will have to use the command /usr/sbin/alternatives instead of update-alternatives as root. Somebody try out in Fedora and let me know.
Ubuntu linux, by default performs an ‘fsck’ one every 30 times the file-system is mounted to make sure the hard disk has no errors.
Sometimes you may need to perform an ‘fsck’ during next boot. Here’s the solution -
Create a file /forcefsck without any contents. This can be simply accomplished by
$ sudo touch /forcefsck
The next time you bootup fsck will be performed on all the partitions of your hard drive. Since the file /forcefsck is deleted during the bootup process, this will force ‘fsck’ just ones.
On the contrary, if you frequently turn off your machine, you may be annoyed by regular fsck done every 30 times filesystem is mounted. So, you may sometime wish to disable fsck and boot up fast. This can be done by creating a file /fastboot
$ sudo touch /fastboot
This file is also deleted during the boot up. So this method disables fsck only once. To change the frequency of ‘fsck’ according to your need you may use a very good utility ‘tune2fs’.
Check out its man pages for more details.
P.S.: These methods are generic to all Linux distros, but I am not sure about the frequency.
