A few days ago I discovered an interesting use of process substitution
and the read function. This makes it possible to read more than one
string from a sub shell without loosing the original standard input.
You can find the details here: http://goo.gl/6txBH
The result is a bit cryptic. Does anybody know a simpler solution for
this problem?

The solution on your web page only works on systems that use /dev/fd,
not a FIFO, for process substitution.
