Hi Gezim,

How are you running the script? There are environment variables that
affect the separator characters used by the shell - maybe that is the
problem.

You may want to verify the /bin/sh is a symlink to bash.

As you say, the syntax in the script above should be fine (works for me
in FC3).

Cheers, Ben
