ls head and gv

[David Niklas]

I used this command:
alias lgv="gv "$(ls -c *.pdf | head -n1)" &"

What I expected was the latest pdf document to be brought up in gv and gv
goes to the background.
What happens is that a semi-random pdf document is loaded into gv and gv
goes into the background.

Any ideas?

Thanks,
David
