Simple shell implementation. Tutorial here ->
LSH is a simple implementation of a shell in C, and it is the subject of a
tutorial on my website. It demonstrates the basics of how a shell works.
That is: read, parse, fork, exec, and wait. Since its purpose is demonstration
(not feature completeness or even fitness for casual use), it has many
limitations, including:
cd, help, exit.Use gcc -o lsh src/main.c to compile, and then ./lsh to run. If you would
like to use the standard-library based implementation of lsh_read_line(), then
you can do: gcc -DLSH_USE_STD_GETLINE -o lsh src/main.c.
Since this is the subject of a tutorial, I’m not looking to extend it with
additional features at this time. So I won’t be accepting any pull requests
that aren’t related to bug fixes (and I’m sure there are still bugs in the
code!).
However, that doesn’t mean that you shouldn’t play with the code, make changes,
and explore new features! That’s the whole point of this project! It’s just
that other people are doing the same thing, and this project is merely a
starting point for your own exploration.
On that note, I would be just tickled if you dropped me a line (see my website
for contact info) to show me the cool new features you’ve added!

appreciate, but don’t require, acknowledgement in derivative works.
