good examples @Scrutinizer Smilie
i believe these must be like below(just little correction).
Code:
awk 'getline x<f{print x,$0}' f=file1 file2

Code:
awk 'getline $(NF+1)<"file2"' file1

third is can be like this
Code:
awk 'getline $2<"file2"' file1

regards

@ygemici, you are correct about the first one. The second one was write in haste...

It should be:
Code:
awk 'getline $(NF+1)<f' f=file2 file1

The third one was correct...
