=====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=== Demonstration of the chosen keyword. lab46:~$ ls Maildir badname file.txt.gz shell archive1.tar.gz badname.tar.gz lab2 src archive2.zip courses.html lyrics.mp3 src.bak archives **example.txt** public_html the answer.txt lab46:~$ mv example.txt example1.txt lab46:~$ ls Maildir badname file.txt.gz shell archive1.tar.gz badname.tar.gz lab2 src archive2.zip courses.html lyrics.mp3 src.bak archives **example1.txt** public_html the answer.txt lab46:~$ mv example1.txt -t src lab46:~$ ls Maildir archives courses.html lyrics.mp3 src archive1.tar.gz badname file.txt.gz public_html src.bak archive2.zip badname.tar.gz lab2 shell the answer.txt lab46:~$ cd src lab46:~/src$ ls **example1.txt** src lab46:~/src$ ====Keyword "touch"==== ===Definition=== "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. ===Demonstration=== Demonstration of the chosen keyword. lab46:~/messaround$ touch example.txt lab46:~/messaround$ ls example.txt lab46:~/messaround$ touch example1.txt example2.txt example3.txt lab46:~/messaround$ ls example.txt example1.txt example2.txt example3.txt lab46:~/messaround$ ====Keyword "motd"==== ===Definition=== "motd" is the message of the day. It is displayed after the user logs in or after using the command "motd". ===Demonstration=== lab46:~$ motd __ _ _ _ __ . . . . . . . . . . . . . . . . . . . . . . . . . | | __ _| |__ / | |_/ / .

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.
