can't start csh (scripts) (PR#8220)
This works perfectly correctly in four separate configurations (32-/64-bit x gcc/cc) on our Solaris 8, and I can see no change in the R sources for do_system since Mar 2004. Are you sure that it is not something in your build environment that has changed since 2.1.1 was built? Please confirm that if you build 2.1.1 and 2.2.0 with the same tools they behave differently, and if so tell us what those tools are. All R is doing here is to call the C system call and the output comes from the shell directly to the terminal, without any intervention from R. You might try a command that actually does something permanent to confirm that csh is executing it: if that is the case the issue is how csh writes to your terminal.

/hom1/users/gloeckler csh (in contrast to the shells used above) doesn't give any result:

Outside of R csh and csh scripts do not cause any problems. I tracked down a problem with starting an HTML browser down to this problem with the invocation of any csh process. The csh used is the normal C-Shell shipped with Solaris 9.
