unix Keywords
Keyword "cd"
Definition
My definition of the command “cd” is that it is an abbreviation of change directory. With just the command “cd” it will, by default, change the directory to the home directory. If the command “cd src” is used then the directory will be changed (like in the demonstration). With the command “cd ..” the directory will go to the one previous the one it is currently in. (as shown in the demonstration again). Also the command cd can be used to change to directories in directories such as my example, “cd src/src/unix” which will take my directory and change it to “lab46:~/src/src/unix$”
Demonstration
lab46:~$ cd src lab46:~/src$ cd .. lab46:~$ cd src/src/unix lab46:~/src/src/unix$
Keyword "pwd"
Definition
The command “pwd” means that it will show the path that the current working directory is in. The directory path to the home directory, for me, is “/home/mfaucet2”. As the command “cd” is used the pwd output is either longer or shorter.
Demonstration
Demonstration of the chosen keyword.
lab46:~$ pwd /home/mfaucet2 lab46:~$ cd src lab46:~/src$ pwd /home/mfaucet2/src lab46:~/src$ cd /home/mfaucet2 lab46:~$ pwd /home/mfaucet2 lab46:~$ cd .. lab46:/home$ pwd /home lab46:/home$ cd .. lab46:/$ pwd / lab46:/$
Keyword "mv"
Definition
The “mv” command is just a sorter way to say move. The “mv” command has two functions; One function is to move the command (obviously). The second function is to rename the file/directory/archive/what-ever. A way that I found to use the “mv” command is the following: mv “filename” -t (I think “-t” is “to”) “new filename or new directory location” and voila the file is moved.
Demonstration

Keyword "touch"

“touch” isn't touching a file or directory or archive. The command “touch” is how files are created. Using the “touch” command can be used to create 1 - x amount of files all in the same command.

unix Objective
Objective
To learn more about how Unix functions and learn the commands to help make everyday work easier.
Definition
The easiest way to find out the functions of Unix is to play around with them. Some help with work that needs to be done and other help make the experience more enjoyable. All around Unix just helps makes doing things easier.
Method
In order to help me achieve higher learning in Unix i will have to do the assignments for the Unix Fundamentals class. In order to do these I will have to be fully engaged in critical thinking and completely indulged in the work that needs to be done.
Measurement
After following my method of achieving higher learning in Unix I have now understood the most recently due assignments after learning how Unix commands work. To achieve this I did what my method said and have handed in my assignments on time.
Analysis
The keywords in the above part of the opus are commands that I have become more familiar with and are more comfortable using those commands without making a huge mess in my virtual machine, like I was when the class first started out.
