Hi!
I'm doing this:
------- script.sh -------
#!/bin/ksh
for word in $(tr '\n' ' ');do
# ^^ tr(1) reads from standard input
... some stuff ...
done
read FOO
case "${FOO}" in
... ... ...
esac
------- script.sh -------
$ script.sh < /foo/bar
The problem with this of course, is that I want `read' to read from the
user interactively, also from stdin, but stdin is piped to the script
(and subsequently to tr(1)) before `read'. So now `read' just gets eof.
I'm thinking about something along the lines of first "closing" the
stdin that is piped to the script (somehow, I don't know), then
reopening it (also, somehow). I know this sounds vague, but does the
concept makes sense at all?
I was playing around with something like this:
for word in $(tr ..);do; ... ;done
exec 3</dev/stdin
exec <&-
exec 0<&3
read FOO
Thanks for any pointers!
Daniel
