Some Notes

Many of these files are dependent on one another. For instance, the create.bash file actually doesn't have built-in capability to create anything on its own. You'll notice how bare bones it is — this is because it is actually wrapping update.bash which handles creating and updating files. You'll notice something similar going on with the enroll.bash script as well, which is just wrapping update.bash.

To handle state across files, the read.bash script is using an associative array to store values in a global for the current file context. Very C style. By reading out of this array we can maintain better create/read/update management across the files.

Likewise, you'll notice a distinct lack of echo command usage. I instead opt for printf which is better practice and cat with heredocs to output into files.

You'll also notice a err and log function that are used all over the place, with the intent being that assign1.bash is the entry point for this program. Attempting to use any script in isolation without assign1.bash will likely fail in unexpected ways.

Another thing to note is at the top of each script I define set -eEuo pipefail which avoids all sorts of pitfalls when bash scripting, like early exits on failure, failing pipelines, checking unassigned variables, and more.

Last thing, I do not use the source command, instead using the better POSIX standard . to source the various scripts within the assignment.
