====unix Keyword 1====
Local host

 
===Definition===
Local host is is the standard hostname given to the address of the loopback network interface or the web address of the computer you are working on. Although local host can take different forms, the web address is simply your computer's identifier.

===Demonstration===
a computer connected to lab46.corning-cc.edu through ssh is an example of a remote host
====unix Keyword 3====
File Manipulation
===Definition===
file manipulation is the ability to control files such as moving them, removing them, copying them. 

===Demonstration===

lab46:~/src/cprog$ cp file123 file2
lab46:~/src/cprog$ rm file123
rm: remove regular empty file `file123'? y
lab46:~/src/cprog$ mkdir file123
lab46:~/src/cprog$ rmdir file123

lab46:~$
</cli>

by typing pwd you are shown where you are at in relaton to directories.
Also by typing in cd you are defaulted back to your home directory even if you are in another directory. 
<cli>
lab46:~$
lab46:~$ pwd
/home/rmatsch
lab46:~$ cd src
lab46:~/src$ cd
lab46:~$
</cli>

====unix Keyword 5====
Current working directory

===Definition===

The current working directory is the directory that you're in. 

===Demonstration===
The current working directory is the directory that you are in. Typing cd command with no arguments will change your current working directory to your home directory.The pwd command reveals the current working directory.

<cli>
lab46:~$ cd src/unix
lab46:~/src/unix$ pwd
/home/rmatsch/src/unix
lab46:~/src/unix$ cd
lab46:~$ pwd
/home/rmatsch
lab46:~$

</cli>

====unix Keyword 6====
Text Processing
===Definition===
Text Processing is a tool used to edit text, save text into files or from files but can also be used to change it other text files.

lab46:~$ nano hello.c
</cli>
<code>
#include<stdio.h>

===Demonstration===
hello1.c is a txt file,unix is a directory that contains other files,and hello1 is a compiled c code program.

<cli>
lab46:~/src$ ls
Makefile  cprog  hello1  hello1.c  submit  unix
lab46:~/src$
lab46:~/src$ cd unix
lab46:~/src/unix$
lab46:~/src/unix$ ls
arc.tar.gz    cs1.txt  cs3.txt  cs5.txt   lab1.txt  lab3.txt  lab5.txt
contact.info  cs2.txt  cs4.txt  lab0.txt  lab2.txt  lab4.txt  shell
lab46:~/src/unix$

</cli>

===Definition===
The objective entails being familiar and comfortable in using unix to accomplish task. It also entails understanding basic understandings of unix.
===Method===
The method i use for measuring successful academic/intellectual achievement of this objective would be to be asked to complete various task to be completted in a timly mannor for a final.

===Analysis===
upon reflect  my achievement of the particular course objective.
i would do pretty good.
