Hi Brian,
I'm unable to test on 10.3 any longer (old machine died) but I'd
expect some thing like:
set fexists to "if [ -e /Library/WebServer/Documents/ ]; then
echo \"Kilroy was here\"
else
echo \"Kilroy was not here\"
fi"
do shell script fexists
to work on both systems. For paths in AppleScript, I actually prefer
to use System Events even though it usually requires more work to get
the same result. For POSIX, paths I mostly use Tcl:
do shell script "echo 'puts [file exists /Library/WebServer/
Documents]' | tclsh"
--> 1
As you can see, the terminology is not quite as obscure as sh. The
above is compatible back to 10.0
