crash

crash is a unix shell in c++ I'm writing for my Operating Systems class.

For debugging with gdb, make sure to pass the argument "-DCMAKE_BUILD_TYPE=Debug" into cmake.

To build and run the unit tests, follow the instructions located here to setup the googletest framework: https://www.eriksmistad.no/getting-started-with-google-test-on-ubuntu/

Use the command "set follow-fork-mode child" within gdb to debug the child process from the forkAndExec call.
