Topic 2: In-Class Activity - Exploring the Command Line

In-Class Activity: Exploring the Command Line

Objective: The goal of this activity is to put into practice the shell commands learned in class, including file navigation, file manipulation, and simple scripting.

Instructions:

1. Shell Basics:
   • Open your terminal or command line interface.
   • Identify which shell you are using with the command echo $SHELL.
   • Use man or --help to look up the manual for the ls command.
2. Help!:
   • For each of the following commands, use --help or man to find out what they do: cd, mkdir, rm.
3. Navigating Your System:
   • Navigate to your home directory using cd.
   • List all the files and directories in your home directory with a detailed view using ls -l.
   • Create a new directory called ds_activities.
4. Managing Your Files:
   • Inside ds_activities, create a new file called my_script.sh.
   • Copy any text file from your system into this directory and rename it to sample.txt.
5. Working with Text Files:
   • Use cat to display the contents of sample.txt.
   • Use head and tail to display the first and last 10 lines of sample.txt.
6. Redirects, Pipes, and Loops:
   • Redirect the output of ls -l to a file named directory_list.txt.
   • Use a pipe to sort directory_list.txt alphabetically and display the results with less.
7. Scripting:
   • Edit my_script.sh to include a bash script that prints “Hello, Data Science!” to the terminal.
   • Make my_script.sh executable with chmod and run it.

Submission: - Compress the ds_activities directory with all created files into a .zip file and submit it through Gradescope in the Lecture Quiz 06. - Name the zip file FirstName_LastName_ds_activities.zip.

Note: Remember to replace FirstName and LastName with your actual last and first names.
