That was the problem.

Thunderbird did
but I deleted it to save space.

But then I have to connect this directory to the path command.
Example: I create shell files and I save them in my directory: dailytodo.

Is it better for not confuse myself to name it mybin

Thank You.

Then Linux is searching
when I give comand like dothisnow
in the

bin or mybin
for
dothisnow.sh.

This does mean
I close the terminal
and Linux will forget it.
