R devel - Oct 2005 - can't start csh (scripts) (PR#8220)

Dear R developers,

after upgrading from R 2.1.1 to 2.2.0 I can't start csh (scripts) anymore.

While the following commands work fine

  > system("tcsh -c pwd")
  /hom1/users/gloeckler
  > system("bash -c pwd")
  /hom1/users/gloeckler
  > system("ksh -c pwd")
  /hom1/users/gloeckler

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

  > system("csh -c pwd")
  > 

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.

Thanks in advance,
Jens Gloeckler

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.
