Entry 1: August 31, 2012
Today we finished going over the starting info. Same old Matt no matter what we are doing we end up going off on a tangent about something, today was a quote “Any Technology, suficcient, advanced, is indistinguishable from MAGIC!” -Isaac Asimov- so that was the first of many. Just saying the opus is not my favorite part of this class but it might be better then before. My choosen keyword is 'drum roll' file copying/moving/renaming so lets see what we come up with by Sept 15. Weird chats going on in the class chat. Made a new dir in lab46 for this class called unix. Went through old programs so I could get a refresher course on c/c++.
Entry 2: September 14, 2012
Today before class I printed of a list of commands for vi so that I can practice at home. Finished my keyword(s) so that it is out of the way. We just made vi different but it must be in a good way, I still prefer nano over vi but I give vi a college try. Its magic time. Made a file then said hello. STDIN, STDOUT, STDERR now words and basic to under stand. Learning file stuff. How can I work when eyes pop up on my screen. Mathmatical.
Entry 3: Sept 26, 2012
Lost my phone so it made me late for class now Im lost at whats happening. So heres project 1's stuff. 1B is ASCII text. 1C is “This is a simple text file. It contains ASCII text.”. 1D is “file.txt.gz: gzip compressed data, was “file.txt”, from Unix, last modified: Wed Sep 26 16:00:08 2012”. 1E is “file.txt.gz: gzip compressed data, was “file.txt”, from Unix, last modified: Wed Sep 26 16:00:08 2012, max speed”. 2B looks like this “ lab46:~$ cat courses.html !\Àâ ¶¡¹¡±¹1¡¡¡©,Ê@iqIbCyjJz*u9EM

Entry 4: Sept 28, 2012
Finished project 1, darn you Matt for making it so confusing. Yay everything is done for the opus and the first two projects. Chmod hates me just plain out hates me. So I figured out why I was failing so bad it was because I forgot to type .sh at the end of the file name. So I give up I will just listen to Matt.
Keywords
unix Keyword 1
file copying/moving/renaming
Definition
File copying- When you of make a copy of a file or folder using the command cp. File moving- When you move a folder or file to a different location using the mv command. File renaming- When you rename a file or folder also uses the mv command.
References
unix Keyword 1 Phase 2
File Archival
Definition
File archival, sometimes referred to as concatenating files, is used to join multiple files and data regarding those files into a single file which can then be compressed to reduce the amount of required storage space needed for files. Each computer platform or operating system has their own formats for concatenating files. Tar, ar, and shar are the file formats used by Unix operating system to join the files and gzip is the format of the compressed file. Each format is distinct in the treatment of the files. For example, the tar format is used for the creation of tape archives, and has replaced the ar format for most files other than static libraries. The shar format is for shell script archives.

Experiment 1
Question
What would happen if for grep you gave it two or more seperate words/letters?
Resources
Nick Matt
Hypothesis
I believe that it will look for all the words/letters.
Experiment
Im going test this by checking it in a terminal.
Data
First I did who | grep kpryslop | wc -l and got 1. then I did who | grep kpryslop byang | wc -l and got grep: byand: No such file or directory 0.
Analysis
My hypothesis was wrong. grep can take two or more but after the first word/letter it looks for files and directorys.
Conclusions
Grep can take more than one thing but it looks for files/directorys.

PATH environment variable
Definition
The $PATH variable specifies a list of one or more directory names separated by colons.
The /bin, /usr, and /local directories are typically included in most users' $PATH settings. The current directory is sometimes included, allowing programs in the current directory to be executed. Superuser (root) accounts as a rule are not include in $PATH, however, in order to prevent the accidental execution of scripts in the current directory.
When a command name is specified by the user or an exec call is made from a program, the system searches through $PATH, examining each directory from left to right in the list, looking for a filename that matches the command name. Once found, the program is executed as a child process of the command shell or program that issued the command.

Can you give grep to letters/words?
Resources
Hypothesis
It will work and both letters/words.
Experiment
Type it in a command line.

Analysis
grep does allow for two or more letters/words.
Conclusions
This is useful to know how to do.

This is confusing first I get
lab46:~$ ./setup.exe I see you've made it this far. The end is in sight. cat: ./setup.exe: No such file or directory When you figure it out, you want field: 2
Then I get
lab46:~$ ./setup.exe Not ready yet.

Comm
Definition
“comm” is a UNIX command which can be used to compare two sorted files. The input for comm is two files, and the output is two separate columns. The command syntax for comm is
comm [OPTION]... FILE1 FILE2
comm has three main options, -1, -2, and -3.
The -1 option will print the lines present in FILE1 in the left hand column, and all common lines in the right hand column, whereas the -2 option will do the opposite (print lines present in FILE2 on the left, and common lines on the right). The -3 option, however, will only print lines unique to both files, with FILE1's unique lines being on the left, and FILE2's unique lines on the right.

Experiment 3
Question
Can you throw xeyes/xlogo/xloadimage on to a computer without someone logged in.
Resources
Matt
Hypothesis
I believe you can.
Experiment
Try to send xeyes or whatever to a computer not in use.
Data
grrasp:~$ xeyes -display flake02:5 & [1] 20395 grrasp:~$ xeyes -display flake02:5 & [2] 20396 grrasp:~$ xeyes -display flake02:5 & [3] 20397 grrasp:~$ xeyes -display flake02:5 & [4] 20398 grrasp:~$ xeyes -display flake02:5 & [5] 20399 grrasp:~$ xeyes -display flake02:5 & [6] 20400 grrasp:~$ xeyes -display flake02:5 & [7] 20401 grrasp:~$ xeyes -display flake02:5 & [8] 20402 grrasp:~$ xeyes -display flake02:5 & [9] 20403 grrasp:~$ xeyes -display flake02:5 & [10] 20404 grrasp:~$ xeyes -display flake02:5 & [11] 20406 grrasp:~$ xeyes -display flake02:5 & [12] 20407 grrasp:~$
Did this while someone was not logged in at 15:32 November 30th 2012.
Analysis
I was correct in my idea that xeyes/whatever would work.
Conclusions
This could be fun as a jock to play on people.
