Could you please try following.
No need to use tail and echo and then save it to a variable then. awk is capable to read files.Also I don't think there is a need of mentioning IFS there too as we know awk has FS OR -F option to set field separator but if we are NOT setting it, it will set field separator to space only.
Anyways thinking for your problem more as it worked for me by your way too, will let you know if get something.
Thanks,
R. Singh
