Bash Script Error Catching

Question

I am very new to bash scripts, and for my first script attempt I am submitting files to my professor\'s dropbox within the same server.

The code is this:

Answer 1

echo "Submit lab$1?"

read choice

echo "Send to Prof's dropbox"
cp -rv /path/to/lab$1 /path/to/dropbox &>/dev/null

[ $? -eq 0 ] && { #success, do something } || { #fail, do something }

And so on...
