Hi, is it possible to have a process substitution with both input and output redirection? So far I use the following work-around
> cat parentprocess.sh: #!/bin/bash mkfifo fifo 2>/dev/null exec 5> >(./subprocess.sh > fifo) exec 6< <(cat < fifo) echo input to subprocess 1>&5 echo done sending input sleep 1 while read -u 6 ; do echo parent process read: $REPLY done exec 5>&- echo about to exit parent process rm fifo > cat subprocess.sh: #!/bin/bash echo subprocess start read sleep 1 echo read: $REPLY echo subprocess end > Is there another way to do that, something like fork, which wouldn't use a named pipe explicitely?
