I real dont want to use expect because of portability issues.
No offense...but I realy dont undersatnd your example...I see what you are doing...but what are you trying to say?

for now I am using this line:
Code:
`echo 'thepassword | gpg --passphrase-fd 0 -d thefile.gpg`

but that only gets me around the gpg issue, but not the core of the question -> how to pass strings to a running peece of code?!

further question:

how do I put a file (its content whether text or binary) into a shell variable?
This right here is not working:

Code:
file=`echo 'thepassword | gpg --passphrase-fd 0 -d thefile.gpg`
file $file
FILETYPE=`file $file | cut -d " " -f 2`
echo "$FILETYPE"

souldn't file tell me something like this:

Code:
[UTF-8 Unicode text

gpg-mailkeys

GPG-MAILKEYS(1) 					      General Commands Manual						   GPG-MAILKEYS(1)

NAME

       gpg-mailkeys - sends emails containing keys to their owners

SYNOPSIS

       gpg-mailkeys id...

DESCRIPTION

       gpg-mailkeys  sends  the owners of the keys listed on the command line a mail each, containing their public key. After signing, you can use
       this tool to send everyone the new signatures they just got.

       If you're interested in encrypting the signature before it's sent, in order to verify that the associated address actually belongs  to  the
       key owner, you should check out caff

OPTIONS

       None

ENVIRONMENT

       NAME	    Set the name to use when sending messages

       EMAIL	    Set the email address to use when sending messages

       SUBJECT	    Set the subject of the messages you send

       TEXT	    Set the body text of the messages

       SENDMAIL_ARGS
		    Set  arguments to pass to /usr/sbin/sendmail. This can be useful to set credentials in order to authenticate to an smtp server
		    when using ssmtp for example.

FILES

       The behavior of gpg-mailkeys can be updated through some files available in the user home directory.

       Thus, ~/.gpg-mailkeysrc allows the user to overwrite the default value for the above environment variables, and any  text  in  ~/.signature
       will be appended to the end of the body text of the message.
