edit Introduction

I am Umar Muhammad Sheikh. Though jobbing is not the most significant part of my life yet, I can describe it in complete detail right now. This is my first day at AboutUs, and so far, the first hour has not yet expired. Period! My first task is to write my own second home page. The first one I made was in the first introductory computer science course, and I made it for getting a good grade. This is not much different!

1 'CTRL+z' to send a task in the background, and 'fg' to bring it back. if there are more than one programs running, type 'jobs' to view them, and if you want a program called 'xyz' to run, there is a number next to the program 'xyz', example, n. type 'fg n' to run it. 2 'gg=G' to properly indent code (but this is by reaming in the command mode and not entering the : in the beginning) 3 '%s/ab/cd/g' to replace all occurences(the work of g) of ab with cd in a file u opened in vim. this option is given in the command mode 4 'CTRL+w+v' so that the same file opens again vertically next to itself
