You're right. This is what I wanted to do:

   while true
   do
       ssh -R a:b:c host
       sleep 10
   done </dev/never >/dev/null

But I could do it like this:

   while true
   do
       sleep 100000
   done |
   while true
   do
       ssh -R a:b:c host
       sleep 10
   done >/dev/null


Thank you.


Marko

PS Are /dev/null and /dev/zero also redundant?
