refer man join for more details
In order to use join the input files should be sorted.
On Solaris, for example, using bash (because of the process substitution),
you can use something like this:

Code:
join -o 2.1 2.2 1.2 <(sort dkl) <(sort gdl)

Code:
nawk 'NR==FNR {_[$1]=$0}
NR!=FNR {
if(_[$1]!="")
	print _[$1]" "$2
}' f1 f2
