Only problem I see is that you are going to get false positives if
the file actually IS a shell script. You might try nibbling a little
more to get something Metacard/Rev specific.
Also, I know the file format has changed a couple of times in recent
history -- you might need to check if they have finally banished the
old Metacard shell script prelude, in which case the function would
fail.
Lastly, I think your script is still going to load the whole stack
into memory before reading off the first line. If you want to read
just 1 line, you'll need to use open / read / close file commands.
Is there a compelling reason to not just check for the existence of
the file, and that it has the appropriate file extension? Then also
check for errors when actually opening the stack?
return ((there is a file pFilePath) AND (char -4 to -1 of pFilePath
is ".rev"))
HTH,

I need a robust alternative to "if there is a stack pFilePath"
that does
*not* load the file into memory and potentially cause problems
with shared stack
name space.
Can anyone improve or see anything not foolproof with this?
function isAstack pFilePath
return line 1 of url("file:"&pFilePath)="#!/bin/sh"
end isAstack
