Ugh, I don't know how it looks in your email client, but the
formatting on my last post is almost unreadable on mine. Here it is
again in a (hopefully) more readable condition. Sorry about that.

There are several of ways to do something like this and it's fairly
trivial as long as you have a little patience in exploring your
options. Here are a few things that come to mind:
(1) Work entirely within AppleScript:
Here's a basic start for a script that you can develop further:
property theCommand : ""
tell application "BBEdit"
tell window 1
set currentSelection to selection as string
set theCommand to text returned of ¬
(display dialog "Enter shell command:" ¬
default answer theCommand buttons {"Execute"} ¬
default button 1 with icon 1)
try
set theOutput to ¬
(do shell script theCommand & " '" & ¬
currentSelection & "'") & return
on error errMsg number errNum
beep
display dialog "Error: " & errNum & ". " & errMsg ¬
with icon stop buttons {"Cancel"} default button 1
end try
set selection to theOutput
end tell
end tell
(2) Use BBEdit Unix Filters, avoiding AppleScript altogether:
Without AppleScript, it's more difficult to collect input from a GUI
prompt. But you could write a Unix Filter for all the shell commands
you want to perform, where only the text to be processed varies.
Or, if the commands themselves vary as well, you could type them in
BBEdit and pass them along to a Unix Filter as part of the input. Then
"eval" the entire thing from within your shell script.
Here's an example of the latter approach using Python (but you can use
any language you want):
#!/usr/local/bin/python
import fileinput
import string
import os
if __name__ == "__main__":
cmdResult = ''
for my_line in fileinput.input():
cmdResult = cmdResult + os.popen(my_line).read()
print cmdResult
(3) Combine options 1 and 2 above:
This is an AppleScript I threw together a while back and never really
finished, so there's lots of room for improvement. But the basic idea
is to execute the selected text as a shell command, like we did in
option 2 above.
The difference, however, is that because it uses AppleScript, we can
do some fancier things: use a different interpreter based on the
source language of the current document ('php -r' for PHP code, 'perl -
e' for Perl, 'ruby -e' for Ruby, etc.), display GUI error dialogs, and
have more flexibility in how the returned text is presented.
Give it a try if you're interested, and feel free to modify it to suit
your needs.

(4) Use a BBEdit shell worksheet, a special document type that allows
you to store and execute Unix command lines. See page 322 of the
BBEdit User Manual for more information.
Hope this gives you some ideas.
