Was fullpath exported? Is this run in a shell?

running fullpath=/etc/udev;export fullpath;foo.sh produces:

/etc

running fullpath="";export fullpath;foo.sh `pwd` produces:

/home

My bad. I should have checked the man page ...

`-'
Signal the end of options, cause all remaining ARGUMENTS to
be assigned to the positional parameters. The `-x' and `-v'
options are turned off. If there are no arguments, the
positional parameters remain unchanged.

I've always used set +x +v to turn off debugging. Didn't realize "set -",
without the +x +v would turn them off.

If the dirname is a link. Try changing 11 to 10 in the awk statement.
