Calling Cygwin from Dos - problem with sub program

Calling Cygwin from Dos - problem with sub program

[nlian]

Hi,

I have a bash script (e.g. test.sh), and I have the following  command
inside the script:

#!/usr/bin/bash
export PROG_LIB="D:\batch\prod\prog\lib"
export PATH="$PROG_LIB:$PATH"

#include functions from functions.library file
. functions.library

#Using logmsg function:
logmsg "This is the beginning" 
====

When I ran from cygwin, I got no error when executing the shell script
(test.sh), all OK.

However when I execute from dos, I got an error: 
         functions.library: No such file or directory
         logmsg: command not found

Here is my dos script,  test.cmd:

@echo off

D:
chdir D:\cygwin\bin
bash --login -c '/cygdrive/d/Batch/prod/prog/scripts/test.sh'

Any idea what's missing / went wrong?

Thanks,

Lian

Non-portable use of back-slashes.  But more importantly, a non-POSIX path
inside a bash script.

| export PATH="$PROG_LIB:$PATH"

Running this script with 'bash -vx', or adding 'cmd /c echo %PATH%', may
prove instructive of what you are setting PATH to.  For starters, the
leading D followed by a path separator : means that you are searching the
relative directory D (and not anchoring a path in the d drive; for that
you need /cygdrive/d/).

Probably because your PATH wasn't set correctly.

Hi Eric,

You are genius! :)
I change the path to use /cygdrive/d/ and it works!

Cheers,

Lian
