you need to quote to avoid expansion, and your sed is a little out:

Code:
 echo '$DESTDIR/$PKG/$VERSION' | sed -e "s/\\$/XXX/g"
XXXDESTDIR/XXXPKG/XXXVERSION

I feel that you need to escape $ by adding '\' everytime you append it to k.
yes i see ...expanded variables when i do "echo $k".
To escape $ first i need to replace "$" with "\$".. thats the problem I am facing.

ok. you can turn off variable expansion by having the string in single quotes:
k='$a$b'
echo $k --> returns $a$b
please try to form the string as above.

If you tell me how to convert it into '$a$b' ... then I will be greatful.
