Shell/Terminal Review

When working from the terminal there are a few file based commands that are used on a daily basis and you will need to be comfortable using them through the course.

Common Commands

• cd
• mkdir
• touch
• open
• ls
• pwd
• mv
• cp
• rm
• echo
• less

Exit Codes

Usually when we run commands from the terminal, they will automatically exit after doing a bit of work. We can also run applications from the terminal that run until we tell them to stop. Other times, there may be an error in a script that makes it hang up. For these situations, it is vital to know the different ways to send manual exit codes to your shell process.

• CTRL + C - Code 130 - Manual exit from script
• CTRL + D - End of File
