How would you represent EOF in bash?

Question

I\'m trying to do something like

read -d EOF stdin

for word in $stdin; do stuff; done

where I want to replace \'EOF\' for an actual repre

Answer 1

To find what a control character is, run

$ cat | od -b
^D
0000000 004 012
0000002

I typed ^V^D after issuing the command, and then RET and another ^D (unquoted) and the result is that EOF is octal 004.

Combining that result with read(1):

$ read -d "$(echo -e '\004')" stdin
foo
bar quuz^Hx
^D
$ echo "$stdin"
foo
bar quux
$ for word in $stdin; do echo $word; done
foo
bar
quux

Yes, I typed ^H above for backspace to see if read(1) did the right thing. It does.
