[wellylug] Running a command in the background which expects keyboard entry

[David Harrison]

Thanks for the assistance.
I now have a functional init.d script for iFolder (based on the Suse  
template)

For anyone interested I've included it below.
If you're interested in compiling your own iFolder simple server  
there's some simple to follow instructions here:
http://forge.novell.com/modules/xfmod/cvs/cvsbrowse.php/*checkout*/ 
ifolder/ifolder/HOWTOs/SimpleServer-Setup-HOWTO.txt

It worked fine for me on Suse 9.2 and there is prebuilt clients for  
Windows, Linux and OSX.

Regards,


David
