Shell Programming and Scripting

After I move the file to a directory, I need to gzip and encrypted.
I never do this in a shl script, I do it from the command line and it works..
cd /home/nelnet

spinel:/home/nelnet$ gpg -e 2010_11_07_05_11_xxxxxx_bills.dat.gz
`/home/nelnet/.gnupg/gpg.conf'
`/home/nelnet/.gnupg/gpg.conf'
You did not specify a user ID. (you may use "-r")

Current recipients:

Enter the user ID. End with an empty line:
You did not specify a user ID. (you may use "-r")

Current recipients:

Enter the user ID. End with an empty line: epass
This works in the command line, it gzip and encrypted the file

If you can point me in the right direction, I will appreciated

though the question is not clear, use the --recipient option as printed in error.

refer step 4 here Gpg Key-Pair Encryption and Decryption Examples

Let me see if I can clarify this better: (new a shl scripts and under some pressure to finish this)

I need to take a file from a directory, the last version so I am doing something like this:

$last ls -1 *the_bills.dat* | tail -1

then I need to copy that file to another directory;

After I move the file to a directory, I need to gzip and encrypted.
someting like gzip name of the file.
then encrypted

something like
gpg -e 2010_11_07_05_11_xxxxxx_bills.dat.gz
when you run this command:

It ask you for
You did not specify a user ID. (you may use "-r")

Current recipients:

Enter the user ID. End with an empty line:
You did not specify a user ID. (you may use "-r")

I now the id, (how I can do this in a shl script?)
Also
When you look for the last version of the file in the directory
You do something like this
$last ls -1 *the_bills.dat* | tail -1

And it works you grab the last version of the directory.
But I need to copy the file to another directory
If the file is store in $last(sorry for my ignorance) ?
So you say
Cp $last to the directory?

How I can store the user ID?

So when I have this question
Enter the user ID. End with an empty line: (you entered here)

All this work from the command line, but it I need to put it in a shl script.

By default GnuPG encrypts using Public keys. I think you'll want the --symmetric switch, in combination with the --password-fd switch. See the man page for gpg for more details.
