Nice comparison; very interesting -- good to know!

This adds up over huge numbers of records processed.

Thank you for sharing.  :-D

$ cat dash.sh

    #!/bin/dash
    for i in `seq 1 1000`
    do
      basename "$PWD" >/dev/null
    done
    exit

$ cat bash.sh

    #!/bin/bash
    for i in `seq 1 1000`
    do
      printf "${PWD##*/}\n" >/dev/null
    done
    exit

$ time ./dash.sh

    real	0m0.468s
    user	0m0.010s
    sys	0m0.053s

$ time ./bash.sh

    real	0m0.042s
    user	0m0.033s
    sys	0m0.007s


0.468/0.042 = 11.1428 real-time difference,
[basename "$PWD"] vs. [printf "${PWD##*/}\n"]
