We really enjoy the auto complete feature in bash but it would be great to have it with “yum”. Debian based Linux Users already have it. Red Hat based distros do not ship with auto-complete enabled in “yum” which would be great if they do. Meanwhile here is a small trick to use mighty auto complete with “yum”, this will work with Red Hat as well as Cent OS and Fedora (all versions).
su -
yum install bash-completion
And you are good to go. You can now type “yum install “ and hit [TAB] to load suggestions just like in bash.

Shutter is a free screenshot manager for Linux that can grab your screen, well that’s what every snapshot tool does. Exciting thing about Shutter is that it also allows you to take snapshot of specific area, a particular window or even a website.

I was looking for a solution to share some of my files in my Ubuntu server to others and while thinking of “cloud computing” at that time, I am thinking if i can try to share my files by linking my box to my existing dropbox account or not. Thus, i give a try and it seem it works. Here are the steps how to do it.
Step 1. Download and extract the dropbox client
For 32-bit:
For 64-bit:
Step 2. Extract the file
Step 3. Run the dropbox client deamon wiht the following command:
Step 4. Since the server is not link to any dropbox account yet, so you will see the following message keep showing every few second:
This client is not linked to any account…
Please visit https://www.dropbox.com/cli_link?host_id=ed2986f99681f0a7b0bf1cd36c79d3e9&cl=en_US to link this machine.
This client is not linked to any account…
Please visit https://www.dropbox.com/cli_link?host_id=ed2986f99681f0a7b0bf1cd36c79d3e9&cl=en_US to link this machine.
Step 5. You may now copy & paste the link to any browser by using any computer so that it will start to link this machine to your dropbox account. You will be asking to provide your username & password in order to link this to your dropbox account.
Step 6. Once it’s successful, you will see the the following message in your Ubuntu linux machine:
Step 7. Now you may press CTRL + C to terminate the deamon process now.

So everybody is talking about a cool new Windows 8 feature called ‘Push Button Reset’. It will reset settings in Windows 8 to day #1. You can do the same with Linux / Unix, just run the command given below:
Warning: Do not run the following command on prods as upon executing this will halt your system and reset all basic settings.
At boot you need to change the root password, set new network configuration, time config, keyboard config, auth config (like use ldap or pam etc), and services config. Like Windows 8 IE/MSoffice, it will not modify Linux apps settings. Personally, I prefer editing individual files.
This is not a new feature as Windows 8 fan boys are claiming to be and it’s been around for ages. My best guess is that MS-Windows 8 users are going to use this feature frequently :P
Note: I’ve tested sys-unconfig on Solaris and RHEL. I’m not sure about Ubuntu but debconf provides similar features.
