LONDON | SDC-NOV-2025| JESUS DEL MORAL | Sprint 4 | Feature / Implement Shell Tools Python

[delmorallopez]

Re-implement shell tools you have used (Used Python)

Each directory contains instructions for one shell tool to re-implement.

Good start on these tasks, some things to consider:

Can you think of any problems that might arise from the filenames you have given your scripts?

See also my comment in the files. Mostly these implementations are very good and neat, well done

[LonMcGregor]

Why is this required? is there a reason i should not output the files on the same line?

[delmorallopez]

There is no technical reason to require -1.
The program already outputs one file per line regardless, so enforcing -1 is unnecessary.
I added the check because I thought the assignment required explicitly using -1, but in practice the program should either: treat -1 as the default behaviour, or Ignore it entirely since only one output format is implemented.

[LonMcGregor]

If you re-read the readme for the ls task, can you see where it is asking for -1 to be implemented? You need to be able to test with it on and off. Right now, every time it runs it prints each file on a new line, so even though you removed the option, how will you test if this option is implemented?

[delmorallopez]

You are right and I understand now perfectly the exercise.... I did some changes in the code wehere the program:

-1 changes output behaviour
-a includes dotfiles

• Clean error handling
• Easy to extend later (-l, multiple paths, etc.)

I have tested:
./ls.py
./ls.py -1
./ls.py -a
./ls.py -1 -a
./ls.py sample-files
./ls.py -1 -a sample-files

[LonMcGregor]

Great work,this task is complete now
