Thank you for your answer, but unfortunately it still hangs waiting for the CTRL-D.

Not here. Could you show us the part of your script that uses sha512sum?

Hi,

Sorry for the little bit off-topic.

I have a script that has to performe a hash over a password. Problem is that sha512sum expects CTRL-D to be pressed to return to the command prompt.

I've searched all over Google, but either I didn't do the right search or there is nothing relevant about this.

Bottom line is that I need this command to print the password hash and returns to the shell automatically:

$ sha512sum | xargs echo "password" | cut -f2 -d' '

Any help would be appreciated.

Do you mean this? echo "password" | sha512sum

You might try stdio re-direction:

passwd=<your_password> passwd <<EOF $passwd EOF unset passwd

<snip sig stuff>
