In-Class Lab 1: Submitting a Script Session

Objective: Start a Script Session and Submit on Canvas

Login to hills and start a script session. Practice using comments

Comment the beginning of your code according to the homework submission guidelines

Perform the following basic commands

  1. ssh to hills from either your laptop or from one of our linux PCs
  2. Type in and execute the following command exactly: 
    cp -r /pub/cs/grwoo/cs160a/Lab1 ~

Start your script session using date, pwd and whoami. Be sure to give your script output a meaningful name other than typescript

  1. cd to the new directory Lab1. List it with the -l (lower-case L) option
  2. display the contents of the file README
  3. copy the file README to README1
  4. rename the file wrong to right
  5. find out what kind of file xyz is
  6. list the current directory again with the -l option
  7. list the current directory again with both the -l and -a options. Can you explain the difference?
  8. remove the empty directory dir1
  9. remove the file xyz

Type exit to exit your script session.
