Hello,

So, on linux, I’m forking a new Ruby process. I redirect stdout and  
stderr into a file and then I execute another program via ‘system’.

If I background the main Ruby process, the writing to the log file  
seems to get halted as (I think) it’s waiting for terminal input  
(which it’s not):

$ ./the\_ruby\_program.rb &  
[1] + Suspended (tty input) ./the\_ruby\_program.rb

Any ideas?

Thanks,  
Joe

I should probably mention that the other program that’s being executed  
is rsh, which executes a command on a different machine.
