I am new to bash (used tcsh till now) and I would like that using esc+backspace that the cursor will delete backwards till the very next slash (like I had in tcsh).

I tried several scripts from different AI engines with no success.
For example, I have the following prompt:

ls hello_1_2/hello_1_2_3

If unix cursor is in the end of the line and I am using esc+backspace, I would expect that it will end up with:

ls hello_1_2/

Appreciate your help.
