This is a minimal toy shell written in Python. It was written as a learning exercise.
I wrote a few blog posts about it here.
Features implemented:
- system calls (eg. ls, mkdir, etc.)
- cd
&&command- pipes
Sample:
Scallop>> mkdir hello
Scallop>> cd hello
Scallop/hello>> cd ..
Scallop>> echo hi && echo bye
hi
bye
Scallop>> ls
hello README.md scallop.py
Scallop>> ls | wc
3 3 27
To run from the root directory:
python3 scallop.py
