Exercises: File permissions

Exercise 1:

Find a partner who is in the same group as you. Use the groups command to check.
In your home directory, create a new directory and give members of your group write access to it, but take away read access.
Tell your partner the absolute path to the directory you’ve given them write access to.
Share files by copying them to each other’s shared directories.

Exercise 2:

The data folder contains 200 files. Each file is named according to a type of measurement (A or B), and a location (1-100) e.g. A_21, B_56 etc.

The scripts folder contains a python script which takes the names of an A and a B file as arguments e.g. scripts/calculate_score.py data/A_1 data/B_1

This will calculate a score based on the data in the two files and print it to standard output along with the name of the files used.

Make calculate_score.py executable
Use a for loop to run through the data files corresponding to each location and generate a score
Modify the for loop to save the scores to a file
Use the sort command to find the location with the highest score
