Bash would really be bad idea if it is going to use bash stitching so many gnu utils for this kind of job.
I once had to rewrite a bash script into awk[1] that is big enough and it made the program more readable and the total time execution came down from 12 mins to less than 1 second.
I think maybe the original bash script would have written badly, (each util command will invoke it's own process and it has to piped to others instead of using awk which will be running in a single process).
