But this involves another level of coding and program installation. The trick I used is to use PERL which is built in almost all *nix distributions. Some of the advantages of using PERL within shell script are Easy to embed Perl commands into shell scripts Most of *nix distro have PERL inbuilt Reduced regex or escape character usage Can put formulae into config file and can loop them into the shell script precision, error handling
