Hi,
I've the following script, that reads a set of parameters from a .conf
file and load it into vars... it works OK on my Debian Box but... It
just produces no answer on BusyBox with the exception of a blank line
for each "echo" in the script...
So I'm thinking about it doesn't put values on the vars (that's why it
produces blank echo lines...)
Anybody knows what can be going wrong? Something could be different on
BB? I looks alright to me!
Thanks a lot!!
