Script Help?

[Drew Lane]

I'm not much of a shell scripter.   I've been trying to get the
following script working in YDL 2.x, but it always freezes
up in the middle of processing.  It works fine on my Intel
box with RH 7.2, however.

As I understand it, the script extracts some information from
an .ipk file and writes the info to a text file called "Packages".

Does anyone know what might be the problem?

Thanks,

Drew
