I tried out the new 5.2 RC version of bash and I can confirm the behavior for the SHLVL variable is indeed more traditional again. In my case it was purely a cosmetic "problem" though, that just slightly had me confused. I had no idea it could have more grave consequences like for the other user. Now, I'm patiently looking forward to the release version of 5.2. :-) With best regards, H. Thiele
