Trick is add this around the path add.

That only runs it once.

This is a work around for using ,bashrc when .bash_profile is where this should be done.

I think that advice goes back to a time before modern GUI's.  Now many users have never
encountered a terminal, and distros vary widely in the use of ~/.bashrc, ~/.bash_profle, and
~/.profile.

On my Fedora 35 box, ~/.bash_profile is:

  ----------------------------------ser
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
  ---------------------------

Some distros have complicated ~/.bashrc or `/.bash_profile files with a section devoted to
interactive sessions.   This led to issues where users added settings in the wrong section.  
I often ask users to run a failing command in a terminal where they may see messages
that their GUI tools hide, but getting different behaviours between GUI and terminal has
become a problem.
