I tried that, and it doesn't work. It appears to eat all of
the keypresses, so things like pressing "u" to unzoom don't
work. Here's the rather ugly kludge I came up with:
#!/bin/bash
(cat<<EOF
plot sin(x)
pause -1 "press Ctrl-D to exit"
EOF
cat /dev/tty) | gnuplot
I don't like it much, but it works.
