If you don't add export PATH=/home/larry/bin:${PATH} to your .bash_profile (or .profile, or .bashrc depending on your shell and how you execute it), you'd need to do it each time.  Adding the export into your profile or rc files will make sure that's run at shell execution.  Consult your shell documentation for the correct files and when/if they are loaded at any time.

For example, if you go through the standard login function, bash reads /etc/bash_profile (fallback to /etc/profile), ~/.bash_profile, ~/.bash_login, and then ~/.profile, in that order.  Subshells take the rc files, like /etc/bashrc and ~/.bashrc.  And of course, your various profile and rc files usually contain things like bash_profile's: ". ~/.bashrc" and debian's sourcing of scripts in /etc/profile.d in /etc/profile.

For general use, just add your stuff to ~/.profile and you'll almost always get it for most shells that you interact with.

I don't remember as I did it  long ago.  but when I type echo $PATH, what I get is:

/home/larry/bin:/opt/OpenPrinting-Gutenprint/sbin:/opt/OpenPrinting-Gutenprint/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

does that mean I did? or if I need to export it, when and how often is it needed?

Did you export?

I thought $PATH contained the series of paths searched to find an executable file by the name specified on the command line.  Specifically if my $ENV contains a $PATH which reads:

/home/larry/bin:<more paths>

that an executable file like foo.sh found in /home/larry/bin/ could be run by simply typing foo.sh on the command line.  What am I doing wrong as it does not work though it does if I type ./bin/foo.sh while in /home/larry/?
