cmd && echo true || echo false
...but as you can see, you must be careful about what is in the "true" block to make sure it executes without error, otherwise the "false" block will be executed.
To allow the apt-get return code to pass through, you need to use a more normal if/else block:
apt-get () { if [ "$1" = source ]; then command apt-get "$@"; else sudo apt-get "$@"; fi }
