    Well this is a great article, options except bc is more inclined to developers. In most of the cases for UNIX Linux admin bc is the best friend. There is always multiple way to do single task ultimately result matters

    Nice work.

    Thanks for sharing.

    It is nice, but a calculator (physical or software) seems much easier.

    Awk is a special case since this is basically an interpreter of the awk language. Like that, you could also use perl, python, php, with oneliners.

    Another basic calculator is let:

    # let total=20+5

    Results in $total being 25

    Another way is using perl command:

    # perl -wlne 'print eval';

    then do the calculations

    Why not PowerShell? Available on most OS and far easier than anything you have here
