Due date: Monday, February 8, 2021.

Just as before, you will need to copy the content of the terminal to a file called hw2.txt.

• Find out what your quota is and what part of it you have already used. The command to use is "quota".
  
  
• Display (in the terminal) the list of directories in your home directory with the total size of the files inside them (without the subdirectories). The command to use for this is "du" and you'll need some options to summarize the results.
  
  
• Display the major drives on your computer with the command "df". These three commands were shown in the lecture demos for C151_02_commands.mp4 from last week.
  
  
• Use the command "which" to find the absolute path for the command "grep" that we have used in the previous homework.
  
  
• Display the current date and time (find this command in the textbook or you can try to guess it).
  
  
• Use the command "ps" with appropriate options to display all the processes runing on your computer with a long list of details for each of them. Display the same list using the command "top". I suggest to copy the contect of the terminal to a text file before you use the command top because this command generates a lot of text and you may lose the previous commands. If you're using the putty option of logging to a file, you don't need to do this.
  
  
• Launch the application "pico" from the terminal in the background. For this, run the command terminated with an & character:
  pico &
  
  
• Find out what the process id is for this process (pico). Do not list all the processes active on your computer again, but only those running from the terminal. Kill the process named pico and then list the processes runing from the terminal again to make sure it's not there anymore.
  
  
• Launch the application "pico" again in the background and bring it to the foreground. The command to bring the application to the foreground is "fg" and it is run after the first application was launched. Exit the editor without writing any file.
  
  
• From the list of processes running on your computer, choose one and write down the process id. Find out if this process uses any temporary files while running. For this, you need to check the content of a folder inside /proc with a name identical to the process id. The lecture demos of this week discuss this aspect.

At this point copy the content of the terminal to the file hw2.txt.

Submit: to Canvas, Assignments, Homework 2, the file hw2.txt.
