Website Back up
suramya.com is now back up after a 2 day downtime which was a lot longer than what I was aiming for… But I blame this delay on the server, it took forever to compile and install stuff… Plus I had forgotten how much I had customized the server so I had to re-install everything from scratch to bring it back to normal.
NEways, sorry for the extended downtime. Hopefully the sever shouldn’t be going down so often now. Also I have installed monitoring software on my home machine which will monitor the webserver so I will know if anything goes down and when I need to bring stuff back up again.
Let me know if you have any problems with the site.
Thanks,
Suramya

Find and bind key sequences in bash
This Tip was taken from a TechRepublic article by Vincent Danen. It will allow the user to map unused key combinations to run custom commands in the shell.
To obtain the key sequence from a function key, use the read command. The following is an example of pressing the [F12] key:
$ read
^[[24~
Note that different keyboards will produce different key sequences, and modifiers to the function keys (such as [Ctrl][F12] or [Shift][F12]) will produce other sequences as well.
The next step is to bind that key sequence to a particular shell command. For example, you can bind [F12] to the ‘history-search-backward’ shell command:
$ bind ‘’\e[24~’: history-search-backward’
