Just a suggestion, but numfmt is super awesome and obviates the awk blob.

      fi | if [ $HUMAN -eq 1 ]; then
    -     awk '{ if ($1 > 1024*1024*1024)
    -               printf("% 6.1fT %s\n", $1/(1024*1024*1024), $2);
    -            else if ($1 > 1024*1024)
    -               printf("% 6.1fG %s\n", $1/(1024*1024), $2);
    -            else if ($1 > 1024)
    -               printf("% 6.1fM %s\n", $1/1024, $2);
    -            else
    -               printf("% 6.1ik %s\n", $1, $2); }'
    +     numfmt --from-unit=Ki --to=iec-i --suffix=B --padding=6
