nextfile is not part of posix awk, but it's available on the most popular implementations.
AWK uses extended regular expression, instead of grep's basic flavor. You may need to tweak your regular expressions if they're more complicated than a simple word like "topic".
Since this find prints file, and since you almost certainly don't want to spawn awk once per file, I dropped -n 1 in xargs. Further, sometimes parallelizing i/o bound tasks can degrade performance if the parallel invocations are not backed by different disks. Something to keep in mind. You might actually improve performance by lowering the value of -P (if not by eliminating it altogether).
in aix, i use grep something * to get the files, lines that contain something. but i couldnt get the same result from a sun box. what is the equivalent? thanks (4 Replies)
