Debian10's bash shell now says 'command not found'...

The questioner's Another question has done the following, but it seems that all existing PATHs have been lost.

export PATH=$aw-server:/home/yusuke/.local/bin
export PATH=$aw-watcher-afk:/home/yusuke/.local/bin
export PATH=$aw-watcher-window: /home/yusuke/.local/bin

In other words, when you need to write export PATH="/path/to/new/directory:$PATH" in the form of an existing PATH, the contents of the PATH are almost gone and you can't find any executable files.

If you have not specifically overwritten configuration files such as ~/.profile, you should be able to restart the shell.If you have overwritten it, you can start Bash without loading the existing .profile in /usr/bin/env-i/bin/bash --norc--noprofile and so on to correct the configuration file.
