====Entry 3: November 9th, 2012====

Learned about more commands : head, tail, paste, join, diff, patch, comm...  We learned to filter data with the commands.  

Head - outputs the first part of the file
                 - last | grep cgaines | head -3

Tail - output the last part of the files
                 - last | grep cgaines | tail -3

=====Experiment 3=====

====Question====
Will changing a relevant command in VI by a character completely change the outcome?

====Resources====
I just used techniques used in class to perform this experiment and then started manipulating the commands with no prior knowlegde of what the outcome would be.

====Hypothesis====
My Hypothesis is that by changing one character in the command will change the information 

====Experiment====
I am going to type up some lines in VI and then I am going to input the command. 

Using the command :%s/b/BB/g- this took all of the b's in the entire document and changed them to a BB. 

====Data====
My name is BoBB and we had a BBaBBy its a BBoy, and charlie the unicorn and     very funny.  Billy BBoBB, is a hillBBilly, and a BBig one at that.  Watching     Hogan's Heroes and Hogan always seems to get the girls.  BoBB we had a BBaB    By its a very BBig BBoy.

====Analysis====
Based on the data collected:

Yes my hypothesis is correct, it shows that just changing one character out of the original command will change the result.
 

====Conclusion====
By doing this command I found out the many possibilities could happen when manupulating commands in VI.
