Under Linux, one can look at /proc/$$/cmdline, but I think that it would be better to get this information in an OS-independent way. This would be useful for .zshenv to know the context, for instance, as a user of OpenSSH, to know whether this is a shell used for ~/.ssh/rc (the -c value is '/bin/sh .ssh/rc' in this case). When $DISPLAY is set, I set up a part of my X11 environment from .zshenv, and this includes an execution of xdpyinfo, but before the ~/.ssh/rc script is executed, the xauth authorization hasn't been added yet, so that I get an annoying error message. So, the idea is to disable this set up for this -c value. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
