In the second week:
- we will learn more about the Shell
- we will use Shell commands that could be used to check the content of the files
- we will use
pipesin Shell commands
Software Carpentry provide an excellent introduction to Shell, I recommend reading these two parts to learn about Shell and command syntax:
- Introduction to Shell will give you more overview
- General syntax of the Shell command
If you would like to read more from Software Carpentry to review week 1:
- 👀 Video 👀: Continue watching the ABCD/ReproNim video (the video should open at timestamp 20m3s, and you should watch till 28m45s)
- Use
manto read more about commands:
In the new branch that was created for this week week2 you will find a new directory week2 that will be used as a working directory for this week. Practice using new commands (especially cat, head and tail) for the files in ex1 and ex2 directories.
Use man to learn about different options.
Tip
If you don't remember how to open Codespace, create a new file and add to the repository, you can review instruction from the previous week here
In the new branch that was created for this week week2 you will find a new directory week2 that will be used as a working directory for this week. You should specifically use week2/ex1 for the first exercise. The directory already have 3 files.
Your first exercise will be to open Codespace and merge content of the files in the alphabetic order to a new file week2/ex1/output.txt.
In the week2/ex2 directory you have a file with Massachusetts cities ordered by the population size. I want you to use pipes to sort the cities alphabetically and create a new file week2/ex2/output.txt with the top 10 cities.
Important
Update the repository in order to move to the next week/part of the course:
- Create a Pull Request to the
mainbranch - Check the status of tests
- If all tests pass, merge the Pull Request, this should update a new
README.mdon the main page of the repository (you can reload the page after 30-60s if you don't see the new content)
