Shell Scripting geli attach

[cfw]

I'd like to read -p "Password:" password and then echo $password to geli attach so I don't have to type the same password multiple times.

How do I redirect or pipe the $password variable properly? I know geli attach also accepts a -j /pass/file but I'd rather not save sensitive information to disk.

Use a named pipe

#!/bin/sh
tpipe=/tmp/tpipe_$$
mkfifo $tpipe
echo "text to pipe" > $tpipe &
read  password < $tpipe
echo $password
rm $tpipe

Thanks a lot, named pipes solved my problem.
