Re: cygwin and the rest of the Windows

["Ling F. Zhang" <lingfengz at yahoo dot com>]

Just based on what I have learned so far...I figure
out a more geniune way of how this works:
in cygwin, I made a shell script quo that goes like:
#!/usr/bin/bash
# this program takes user input (STDIN) and put a
quote around it...
# why do I have to do this? well, I can't figure out a
way in dos batch that would do the same...since using
echo autometically adds a "\n" at the end...
printf "\"";
while read LINE
do
  printf "$LINE";
done
printf "\"";

and I wrote something called "bashwin.bat" that goes
like:

@echo off
REM this program is used so that executable in cygwin
written in shell or perl or whatever, can be executed
in Windows command
REM just associate this file in explorer with whatever
you want to run (e.g. .pl, .sh)
cygpath -u %1 | bash -c "quo" > tmp
bash --loging < tmp
del tmp

so now, at command prompt, I can type printenv.pl or
test.sh and they will execute....as if they were in
cygwin, with POSIX path of course...

the problem is, they still won't work as cgi script...
I got a 500 error (or 500 somthing..) and apache
error.log (apache 2.x for win32) reads like:
[Mon Jun 23 03:41:45 2003] [error] [client 127.0.0.1]
(720003)The system cannot find the path specified.  :
couldn't create child process: 720003: printenv.pl
[Mon Jun 23 03:41:45 2003] [error] [client 127.0.0.1]
(720003)The system cannot find the path specified.  :
couldn't spawn child process: C:/Program Files/Apache
Group/Apache2/cgi-bin/printenv.pl
[Mon Jun 23 03:43:31 2003] [error] [client 127.0.0.1]
(720003)The system cannot find the path specified.  :
couldn't create child process: 720003: test.sh

(720003)The system cannot find the path specified.  :
couldn't spawn child process: C:/Program Files/Apache
Group/Apache2/cgi-bin/test.sh

now...that I think has to do with the mixed up of
windows path and cygwin path...anyone can figure out
how to do this?
