Hello Stew,

Could you please try following and let me know if this helps.
Also my solution in POSt#2 also may help you in same.
Code:
awk '/kernel.sem/ { if ($3 < "300") { sub($3,"300",$0); print >> "/tmp/test1" } else {print >> "/tmp/test1" }}' /tmp/test

Here I am creating /tmp/test1 file as output, because file named /tmp/test is input file.

Hope this helps.

Thanks,
R. Singh
