This is a simple POSIX shell application written in pure C. It is an attempt to
understand the *nix Programming Interface. Currently, the shell can perform
basic execution of commands with arguments (such as ls, cat <path_to_file>).
Globbing has been implemented using glob.h, so commands such as ls *.c work
as expected.
To build the shell, run make and a binary called shell will be produced if
no errors occur.
