## Description:

mysh is a a shell that supports both interactive (reads from stdin) and batch mode (reads from a file). This shell will execute jobs supplied by the user, including any native UNIX commands as well as a few custom jobs:

    • jobs - Displays a list of jobs that are currently in the background

    • history - Displays a list of all jobs executed in execution order (including erroneous jobs).

    • wait - tells the shell to wait for all currently backgrounded tasks to complete

    • foreground (fg) - Tell the shell to wait for a specific backgrounded task to complete.

    • exit - Exits the shell


## How to build the software

Simply type 'make' in the working directory of the project through terminal.


## How to use the software

Simply type './mysh' in the terminal while in the working directory of the shell.


## How the software was tested

We used ValGrind to help identify memory leaks, as well as gdb for tracking the source or segmentation faults.

We also used a variety given tests, as well as some we created on our own.

## Known bugs and problem areas

There are certain occurrences of execvp failing (not sure why it happens when it does).
