Intro

• This project was done in duo with Rafael Lacerda
• This is a minishell, recreate some of the shell functionality.
• Learned a lot about how the shell works inside and some new commands.
• My first project in a team (duo).
• We decided to work together on the tasks. And I learned that 2 brains makes thinking process more efficient.
• I learned about pipes, tolkens, execve, builtin functions, and a lot about shell commands.
• Fixed more my knowledge about signals, parsing, File Descriptors, manipulate files.
• After I finished the project I looked for ways of parsing (because it was a lot of work). I found things about parsing algorithms and compiler design. I will study more about this.
