REPOSITORY STEPS
No src? Type into the prompt “fixrepo”. This clones the repositories Matt set up for us this semester. Follow the instructs as they show up on the screen. No need to set up a passkey.
Now, a new directory will appear when you use the ls command, called src. Type in “cd src” to get into this new directory. If you use the command “ls” again, you will see two directories, fall2024 and unix. You will want to cd into fall2024, this is where your semester repository is stored. If you don’t have c4eng as an available directory when you use the ls command, type in “mkdir c4eng“ (mkdir stands for make directory). The cd into the new c4eng. You will keep all of projects here. Nothing is here yet, so you will have to use the grabit command.
