Lab46 Wiki

During the last two weeks of classes, I have spent my time becoming more familiar with Lab46 by logging in the pod systems, opening up a terminal and logging on to Lab46. I was able to start exploring before the semester started because I already had my user name and password. I have never taken the time to get comfortable working within a UNIX system even though I have had previous classes which required me to use it. I have always found myself fumbling around on Lab46 and learning only what I needed to accomplish the required assignments. I didn't have the time to explore Lab46 and UNIX to even have the opportunity to truly appreciate it.

I have learned that UNIX is a type of operating system, which is primarily used by the command line.n In the Lair the local host is the pod of which I am on and Lab46 is the remote host. SRC directory is our repository,

• whoami returns the users name that is currently logged on
  
• who list all the current users on the system
  
• ls list prints the contents of the directory
  
• touch creates a blank file
  
• nano is a text-editor
  
• cat concatenates or sends the output of one or more files to the screen
  
• less allows me to read a file with many pages easily
  
• more allows me to read a file with many pages easily
  
• cp copy, which creates a copy of a file or a directory
  
• mv moves a file or directory to a new location
  
• rm removes a file
  
• file prints the type of file
  
• df shows the partitions and file systems of the computer
  
• chmod changes the shield on the file system
  
• ln links two files together
  
• q to quit
  
• du tells how much space

We also discussed file permissions, which consists of 10 symbols. These symbols are in sections to identify the type of file, the user, the group, and other.
There are 3 types of files: regular, directory, and special.
Each of the 10 spaces is occupied with a “r”- read access, “w” write access, “x” access to the directory, or “-” when denied permissions. Each are weighted differently. R=4, w=2, x=1, and -=0. When a user has all permissions the values will add up to 7.

This is a sample format for a dated entry. Please substitute the actual date for “Month Day, Year”, and duplicate the level 4 heading to make additional entries.

As an aid, feel free to use the following questions to help you generate content for your entries:

• What action or concept of significance, as related to the course, did you experience on this date?
• Why was this significant?
• What concepts are you dealing with that may not make perfect sense?
• What challenges are you facing with respect to the course?
