The ability to control files, such as moving them, removing them, copying them, organizing them.

In this command line sample, you can see me moving files between directories, or for the sake of renaming, copying files, making directories, and removing a file. All of this is file manipulation.

The home directory is your default directory. Whenever you open up a cmd prompt this is the file location that you start at.

So here, you can see that right when I log into lab46 my home directory is denoted by ~$. Using the pwd command (to show the full file structure) reveals that my home directory is at /home/smalik2

lab46:~$ pwd
/home/smalik2
lab46:~$ 

In this example, you can see me moving to a different directory using the cd command. The cd command with no argument takes you back to your home directory.

lab46:~$ pwd
/home/smalik2
lab46:~$ cd src/cprog/Projects
lab46:~/src/cprog/Projects$ pwd
/home/smalik2/src/cprog/Projects
lab46:~/src/cprog/Projects$ cd
lab46:~$ pwd
/home/smalik2
lab46:~$ 

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

The current working directory is basically the directory that you are in. The cd command with no arguments will change your current working directory to your home directory.

The pwd command reveals the current working directory.

lab46:~$ pwd
/home/smalik2
lab46:~$ 

There are three types of files, regular files (such as .txt), directories (technically a file with other file locations in it), and special files (a directory is a type of special file, or C programs).

In the example we see that there are regular files, which are the .c files, directories, and then the special files (the compile C code).

lab46:~$ cd src/cprog
lab46:~/src/cprog$ ls
Feb14    Feb2.c    JAN26_printf_examples.c  JAN31_pointers3.c
Feb14.c  Feb7.c    JAN26_printf_pointers.c  MessingAround
Feb16    Feb7x0.c  JAN31_pointers.c         Projects
Feb16.c  Feb9.c    JAN31_pointers2.c        out.txt
lab46:~/src/cprog$ 

The device that is running the session.

My laptop is running Ubuntu. The terminal on my laptop screen is an example of a local host, because my device (the laptop) is what the services are being ran on.

A remote host is a device that is running services remotely.

My laptop is connected to lab46.corning-cc.edu via ssh, which is an example of a remote host.

The VI editor is a text editor where in one mode you can always insert, and in another mode you enter commands. To toggle command mode you hit escape, and to enter insert mode you push i when in command mode.

lab46:~/src/cprog$ vim Hello.txt
lab46:~/src/cprog$ cat Hello.txt
I couldn't type until I hit I to enter insert mode.

Now, to exit VI editor (and save the work) I will hit the ESCAPE key to enter command mode, from there I will type :wq to quit and save my work.  If I didn't want to save, I would use :q!
lab46:~/src/cprog$ 

After typing vim Hello.txt, this appeared on my screen.

I couldn't type until I hit I to enter insert mode.

Now, to exit VI editor (and save the work) I will hit the ESCAPE key to enter command mode, from there I will type :wq to quit and save my work.  If I didn't want to save, I would use :q!

Manipulating text

You can print the contents of a file using the cat command. You can manipulate text using many things. The nano and vim text editors are really good for editing text based files.

Just nano filename.txt or vim to open the editor.

Familiarity with the structure of UNIX systems.

Basically this means that I will become much more familiar with how UNIX systems look like, like the file structure and whatnot.

If I can tell if a system is based off the UNIX system based on the file structure.

I think I can do this pretty well, as I can recognize that mobile phones (such as my android powered phone and my previous iPhone) are based off of UNIX because of their file structure. They have the files named var, usr, bin, and others.

I think I did pretty well. Not particularly, unless if there is some other discrepancy that I am unaware of. I don't think so. If there was a quick description associated with the objective.
