I've RTFM (and it is indeed a F awful M, grrrrr) to no avail... Is it possible to invoke (from a running sh or csh) a non-login csh that sources .login and then prompts for input as always? (Analagous to bash -login.) I'm sure this is a FAQ, but the existing FAQ list is too general. Shouldn't we think about compiling a comp.unix.shell FAQ list, separate from the general unix FAQ list? thanx! -- Liam Breck breck@umvlsi.ecs.umass.edu

You need to call /bin/csh with a leading '-'. There are two ways to do this. Both should work from sh and csh. 1) use links: % ln -s /bin/csh ~/bin/-csh % rehash #assuming ~/bin is in path % -csh NOTE: this will not work if run as ~/bin/-csh. It must start with '-'. 2) use execl(3V) in a C program: main() { execl("/bin/csh", "-/bin/csh", (char *) 0);} I prefer to do error checking, so I use: main() { execl("/bin/csh", "-/bin/csh", (char *) 0); perror("execl failed:"); exit(1); } in SunOS 4.1.1 on a sun4 under X11R4, I get: /dev/ttyp1: Not owner but it is not a problem later, just an inconvenience. weimer@ssd.kodak.com ( Gary Weimer )
