Where does sudo get PATH?

Question

ubuntu

Faced with strangeness: It is


necessary that /home/lexx/bin be everywhere

Everything is written in .bashrc for root.

It is worth adding that two versions of ffmpeg are installed on the system (one from the turnip, the other compiled from the master)

Answer 1

sudo doesn't take anywhere, sudo executes some command. By default, the shell of the specified user.
If it is bash, then you watch how bash reads its configuration files - /etc/bash.bashrc, /etc/profile.d
$HOME/.bashrc and others can be called from them in certain cases.
Therefore, study the entire chain in your shell (in case you don't have bash by default, but ksh or zsh) and you can specify PATH in the correct file.
Or do not bother and write the full path to the command

Answer 2

Well, write the full path to the binary that you need.
Even in Windows it works.
sudo -u root /home/lexx/bin/ffmpeg
if the system is allowed to execute files from this path, it will run.
