# Instructions
## Compiling
Run `make` in the base folder  
Program is then compiled into bin/

## Running
Run `pish.out` in bin/ to run the program

## Alternative
Run `make exec` in the base folder to compile and run program

# What works and doesn't
Successfully tested:
    As long as the command works alone in Pish, .pishrc is fully functional
    Single commands such as "echo hello world" run fine
    Pipes split commands into parts
    Signals are ignored
    Built in commands such as cd and exit work
    Commands are forked and then exec'd after being split by pipes if any
    Pish prompt works and parses properly

Unsuccessfully tested:
    Redirection operators are found, but not acted upon
    Pipes don't redirect i/o into other commands (i.e. ps aux | grep 'Z')
    Environmental variables being handled by Pish
