What are the Default $PATH Values?

On a default Ubuntu desktop install $PATH is:

$ echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

But in a minimal chroot environment created by debootstrap, $PATH only contains:

# echo $PATH
/usr/sbin:/usr/bin:/sbin:/bin

Environment path values are stored in .bashrc file in ubuntu.

The system-wide PATH variable is defined in /etc/environment

There are path builtin the shells which is

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Then the default path for Ubuntu is:

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
