I have an script that i am running as daemon by init script. (i have written a c program to make it as daemon). I am able to run this script as daemon through shell by calling init script, but it does not work if i am invoking from window prompt e.g.
C:\WINDOWS\posix.exe /u /c /bin/csh -l -c "/etc/init.d/test start" fails to start daemon script
In test init script i am invoking the daemon c prog to run the script as daemon.
is thre any diffrence in invoking the command in shell and invoking command on windows prompt as above.
Thanks

It's likely something in your script.
Do you get an error message?
What is your script?

I am not getting any error message and script works fine if i am invoking it on shell prompt.
This script is used to monitor a windows service and threfore uses wrapper for SC windows utility to check status of service.
In the c daemon function however i am using execl("bin/sh","sh","-c", "/etc/init.d/checkservice.sh");
and my init script /etc/init.d/test calls daemon function to run the checkservice.sh script as daemon.
Thanks

Your script is likely running fine in a shell because the shell is being
displayed within a "console window". The stdin/stdout of a Win32 program
just can't handle some things very well. It's a weakness of many Win32 programs.
So often you need to direct the stdin and/or stdout with a file (typically /dev/null).
Something like "win32prog < /dev/null > /tmp/foo ; cat /tmp/foo".
This is only an example, pipes can often be used as an alternative coupled with cat32.
You might also be interested in using Interix's service utility instead.
