i have been to so many forums to find a solution to this. all the variations are confusing me and none are working.=A0
i am trying to pipe a passphrase to cryptsetup using yad.=A0

=A0pass1=3D`yad --form --title=3D"Enter container passphrase" --height=3D50 --width=3D350 --field=3DPassword:H`

then i strip out the pipe character present between yad variables

pass=3D"${pass1//|}"

at this point the variable pass appears to be exactly what i want.

later on i invoke cryptsetup with the passphrase variable piped to it.=A0

echo "$pass" | cryptsetup --cipher aes-xts-plain --key-size 512 --hash sha512 --iter-time 5000 --use-random luksFormat "$container" -

after a moment, i see the device pop into the selection in my file manager then it dissapears.=A0

the funny thing is, i wrote a terminal only version using the same methods minus the yad things and it works fine(see attached)

terminal version requires 3 confirmations YES, passphrase, passphrase. do i need to reproduce these confirmations even with a minus sign at the end of the cryptsetup line?
if so, would echo "YES"$'\n'"$pass"$'\n'"$pass"'\n' do this?=A0<= /div>

also, if i replace the echo "$pass" pipe with xterm -e cryptsetup.... it works fine. basically, i am not getting the password format piped correctly. ive seen 7 different variations on this pipe and nothing is working. its probably something with spaces but i am resorting to email to lower my bloodpressure. also avoiding forums to lower my heart rate :)

thanks to anyone reading this.

Erik

Hi Erik,

you want to use "echo -n" for piping the password without a trailing newline and "cryptsetup -q ..." in your scripts to avoid any additional user input.
