This is a basic C implementation of a unix-style shell using the REPL paradigm. The shell supports functionality for input ('<') and output ('>') file redirection, piplelining commands ('|'), and background execution ('&'). If errors occur, the user will be notified. To exit, the user must type Ctrl-D. Please use the Makefile to start the shell.

Assumptions: - only one '&' character is allowed - input redirection must occur on the first command (assuming pipelining) - output rediretion must occur on the last command (assuming pipelining) - the maximum length of individual tokens is 32 characters - the maximum length of an input line is 512 characters
