Automator returns different BASH script result than Terminal-

Question

Hello all,
I didn't find an Automator section for OS X 10.6, so I hope this is the proper place to post a question.
Objective:
Right-click on a file, have a Workflow return a TextEdit document or the ClipBoard with the SHA1 hash for that file. I want to bypass opening Terminal every time I have to verify a file's SHA1 hash.
Difficulty:
The SHA1 output from Workflow is not the same as the SHA1 output from the Terminal. Both cases are supposed to run this command:
/usr/bin/openssl sha1 <path and name of file>
Steps taken:
So far, I created a simple Workflow as follows:
Get Selected Finder Items
New TextEdit Document
Run (bash) Shell Script (to stdin): /usr/bin/openssl sha1 $1
Set Contents of TextEdit Document (Appending)
The output from the Workflow looks like this:
4313214a162ed89e5180a7c47a8b0fe2e17801bd
The Terminal output looks like this:
SHA1(Screen shot 2010-03-31 at 2.35.08 PM.png)= 525cf5fb1f6e124a24cb4282a09851ca94d177ba
It is clear that these two hashes are not the same. What I don't get is, why?
Any help here would be greatly appreciated.

Just so others can also benefit from my efforts, I have found the solution and wanted to share.
The Workflow should look like this:
New TextEdit Document
Get Selected Finder Items
Run (Bash) Shell Script (as arguments)
Set Contents of TextEdit Document
The bash shell script should look like this:
/usr/bin/openssl sha1 "$@"; echo "" 2>&1
/usr/bin/openssl sha "$@"; echo "" 2>&1
/usr/bin/openssl md5 "$@"; echo "" 2>&1
/usr/bin/openssl md4 "$@" 2>&1
This will make a very nice output that looks like this:
SHA1(/Users/andrew-grant/Desktop/Home Budgets.fp7)= 59b35dec0dacf9c5f85ec86ded20c385bdc69f30
SHA1(/Users/andrew-grant/Desktop/CHKTAPE.LZW)= 8adf0dd993569c576cfbc1a973e5f3bc2e21533a
SHA(/Users/andrew-grant/Desktop/Home Budgets.fp7)= e9ed0f4a006262ab364069b455e459052e909cab
SHA(/Users/andrew-grant/Desktop/CHKTAPE.LZW)= 01fde6202b0df4d7d8a3f726a5d7681ffc3863ee
MD5(/Users/andrew-grant/Desktop/Home Budgets.fp7)= 01ab9a63aea217fa0ee11a28a4d23eeb
MD5(/Users/andrew-grant/Desktop/CHKTAPE.LZW)= b388e3333a84fe3e821f7c4e1f236950
MD4(/Users/andrew-grant/Desktop/Home Budgets.fp7)= ef2746d7f3fd41f1846fe950ea79a856
MD4(/Users/andrew-grant/Desktop/CHKTAPE.LZW)= 9db75e3347e5e5b446e54b7b883e558d
I hope this helps the next person looking for something similar.
