E.g., one I could use by adding a shebang to my Pascal files:
#!/usr/bin/env fpi
There's instantfpc at fpc's svn trunk: http://svn.freepascal.org/svn/fpc/trunk/utils/instantfpc/
Here's the README:
instantfpc
==========
This tool allows to execute pascal programs as unix scripts.
A unix script starts with a shebang #! and the program to execute. For example
#!/usr/bin/env instantfpc
begin
writeln('It works');
end.
If you save the above file as test.pas and set the execute permission
(chmod a+x) you can execute the script simply with
./test.pas
Installation
============
1. Compile instantfpc.lpi using lazarus, lazbuild or via "fpc instantfpc.lpr"
2. Put the executable "instantfpc" in PATH, for example into
/usr/bin/instantfpc or ~/bin/instantfpc.
That's all.
Now you can execute pascal programs as scripts.
