any way, it seems then to me that even IF "read" was a subshell, the scope
of that would start and end with the read statement.
I don't know why you think that.
thus, magically read in the subshell is making while a part of it's own
No, the pipe is.
there is no "while|read" command, you see.....
so "while" also invokes a shell ? that magically can do which you think is
not possible ??
because it is then the parent, not a child, evidently ?
The pipe creates the subshell.
there is no read command in my path.
so, with that out of the way, what is your comment ?
What does `read` have to do with anything?
