Nearly all of the final actions performed by jdupes (deletion, linking, etc.) can be done by piping the output to a shell script anyway, though it's not as convenient or quick as having the program do it for you. All final actions other than printing match sets can now be disabled, and all of the progress bar code can now be tossed out as well.

The clear downside is that this opens the gates wide for TOCTTOU errors if chosen and I've noted that in the help text.

Hi,
by looking at the code it seems not to be very busyboxified,
no xmalloc, bb_error_msg, getopt32 nor any other libbb
function, do you plan to use them?

Ciao,
