psh is a very simple (and likely buggy) shell I am writing as a learning exercise.
No sane person will ever want to use it.
If you are insane enough to consider writing a shell or looking at how one might be written, then this is for you. Have fun!
For a debug build, run:
make
For a "release" build, run:
make release
But let's be honest, you aren't releasing this garbage code to anyone anyway. But I enjoy feeling like a real developer so I added this rule. make release disable the debug macros so you don't run assertions and stuff.
To clean up the object files for a fresh start, run:
make clean
After you have built psh using make, the binary is saved in the bin directory.
You can execute the program using (assuming you are in the project root):
bin/psh
Really? Do you really want to contribute? Wow! Open a pull request, and I'll take a look.
