In general reusing existing tools with wrappers is a useful technique,
and often preferred over adding options to the tools themselves.
Though in this case we thought it more appropriate to add the status=progress
option to dd itself, as that has the added advantage of updating a single line:

  http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=af2a4ed2

Note also the following related commit which make the handling of SIGUSR1
free from races. See the example in coreutils.texi in the following
to avoid the startup races:

  http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=27d2c738

The above two patches will be in the next coreutils release.

thanks,
Pádraig.

Hi there,


I would like to see dd wrapper "progress-dd" into coreutils.
All it does is to keep sending USR1 to a child dd process to increase
usability of that dd feature.
It's up here:

http://git.goodpoint.de/?p=progress-dd.git;a=blob;f=progress-dd

I'm happy to fix any potential issues about it if your interested in
general.

Best,



Sebastian
