µBash

University project that implements a very simplified shell.
The shell implements the various commands via system calls and the built-in cd command.

Purpose

The purpose of the project was to practice the use of system calls fork, pipe and exec since a key constraint to be met was not to use the system function and in I/O redirection.

Syntax

Since this is a simplified version, command parsing is also simplified by adopting a more limited syntax:

• There must be a space before and after the | symbol.
• No spaces must be present between the > or < symbol and the file where to do the I/O redirection
