With the sample input files you've shown us (and no carriage returns at the ends of the lines in keyfile), I get the expected output in resultFile from protocomm's awk script when I run it on my MacBook Pro.

A slight modification to Jim Mcnamara's grep and cut script also produced the expected output in fesultfile:
Code:
grep -Ff keyfile bigfile  | cut -d ' ' -f 3- > resultfile

but it preserves the double spaces between fields in the input, while the awk script converts the double spaces in the input to single spaces in the output.
