From 1ac8fbeedaf7cba881a7423b92ead1f739b8ac21 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 11:23:19 -0300 Subject: A script whose interpreter is not there is told apart from a missing shell, and Tty refuses it up front Tty's up-front check found the script and let it through, so the pane was made, its exec failed ENOENT, and the log read new, msg shell: shell not found, del, then the err. The check now reads a script's #! line and refuses it, interpreter /no/such/interp not found, and an exec that fails ENOENT on a file that is there says the same.
