Bash Script help
 

Im seriously struggling with getting my head around this class question I have been set, if anyone has a spare moment and wouldnt mind posting some advise on how to tackle this one I would be most greatful.

Create a script called “getinfo.sh” that asks for a London tube station’s name; the line(s) it appears on, e.g., Circle and District; and whether there is a National Rail service from this station. Amend these details to a comma separated value file called underground.csv. Create another script called “sorted.sh” that sorts underground.csv by tube station name in reverse order. The newly sorted file should then be displayed (suitably formatted) along with the number of entries in the file.

Thanks in advance.
