But If I try to do the same thing with R (the statistics package at www.r-project.org) it hangs. Almost the same problem with bc -- output is only seen there if the fwrite connection is closed before doing an fread/fget. R buffers its output in non-terminal mode so I have tried modifying the source of R to force line-buffered output -- no joy. I have also tried calling R indirectly via the unbuffer script that comes with expect -- no joy. I have also tried the pty example program from "Advanced Programming in the Unix environment -- no joy. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20532&edit=1
