How to ignore aliases or functions when running a command?

Simply use command called command as follows to ignore aliases or functions. For example, on my system I've following alias set:
alias apt-get='apt-get update && apt-get upgrade'

To ignore apt-get alias, enter:
command apt-get -y install

You can also use any one of the following syntax:
\apt-get -y install
"apt-get" -y install

Both \ and " symbols allows you to run real apt-get command and ignore apt-get alias.
