strange behaviour from sed???

Hi all,

I want to do a very simple thing with sed. I want to print out the line number of a disk I have defined in /etc/exports, so I do:

Quote:

# sed -n '/md0/=' /etc/exports
3

It's all good, but here's the problem. When I define md0 in a variable, I get nothing from sed:

Quote:

# dev="md0"
# echo $dev
md0
# sed -n '/$dev/=' /etc/exports
#

Why is that? can anybody please help?

Thanks
