Bash – Restart bash from terminal without restarting the terminal application (mac)

bashshell

I've looked around and bit for an answer to this question but I don't seem to find it (which is weird).

My question is, is there any simple way to restart the bash session from within the terminal on mac. I just want the same behaviour as if I closed the terminal application and started it again (all variables reset, .bash_profile sourced etc).

I know how to source .bash_profile, but that's not what I want. One of the reasons I want to do this is because a plugin for my bash prompt has code that prevents colors from being loaded multiple times. Therefore, sourcing .bash_profile doesn't reload the color variables and I have to restart the terminal application to get changes in effect.

exec bash should replace the current shell process with (a new instance of) bash.

So what does the man page tell us about huponexit?

If the huponexit shell option has been set with shopt, bash sends a SIGHUP to all jobs when an interactive login shell exits.

EDIT: Emphasizing that it is a LOGIN shell.

EDIT 2: interactive deserves equal emphasis

You can write it as any of those:

echo -e "\e[1;38;05;${code}m $code: Test"
echo -e "\e[1m\e[38;05;${code}m $code: Test";
echo -e "\e[38;05;${code}m\e[1m $code: Test";
echo -e "\e[38;05;${code};1m $code: Test";
tput bold; tput setaf "$code" # provided the terminfo database is
                              # properly populated

You can run tput bold only once provided you don't reset the boldness with a tput sgr0 or \e[m or \e[0m.
