Java processes have a Runtime object which has an exec() method,
but again I have been unsuccessful in my minimal attempts to
use it.

Hi All,
Schip,
Thanks for the effort.....It was gud to see that u atleast made an
attempt to extend what both of us seem to know............
However from my side, I seem to have found a work around that now
requires the code from a file (a.sh) to be copy pasted on the bash
shell. I was just trying around a lot of things and came across that
this works fine ..
1. From 'run' start a bash shell ( bash.exe) , make sure the bash path
is set in path variable.
2. copy paste the whole of a.sh command on the bash shell.......
I know it is a low level kinda work around ....... but it works :)
It works just fine........ All this above has to be done from java ..
hmm .. Your inputs would be very helpful.
Thanks
Amrit

What you seem to want to do is to run a cygwin bash script from
an MSDOGS command shell, right?
The first place to look is reading the bash manual page.
From a bash shell type: man bash
However that hasn't helped me on this. Your a.sh script contains
bash commands and needs to be interpreted by that shell. The man
page seems to indicate that you can run a script file something
like "bash a.sh", but that doesn't work for me. It might just be
an issue of getting the right environment settings, but
"bash -l a.sh" doesn't seem to work right either...
I can however do this from DOS:
bash -c "echo some stuff; type java"
so you could put your short script on the command line itself...
Anyway, your b.sh script is being interpreted by DOS,
so it starts bash, which exits immediately, and then tries to
run the subsequent commands in the DOS shell. Each line is a
separate DOS command... DOS doesn't seem to have the equivalent
of the "Here Document" to embed scripts, but you could try
using different files somehow.
mostly useless, I know...
