Customize adb prompt

Question

How to reduce the length of the path printed before the shell prompt opened with adb shell ? My problem is that it is so long that I can no longer see my commands, because it does not automatically interrupt the line. I would prefer something like the name of the current directory or an example of abstract code.

sh -v on an android phone gives me

You can change the PS1 prompt as something smaller with the line:

 PS1="> " 

but it would probably be better to increase the width of the window with something like:

 COLUMNS=150
