dd built-in progress introduced in coreutils 8.24

On BSD, unlike Linux, many utilities including dd(1) will dump a progress report when receiving SIGINFO. This was traditionally bound to ^T in shells, either by default or using stty(1).

It's SIGUSR1 on Linux, however there is no signal bound to ^T in Linux, nor is it apparently possible to bind new ones.

`killall -USR1 dd` works like a charm, or for the impatient: watch killall -USR1 dd

This example highlights a very useful alternative function of `watch`: to simply run a command on regular intervals without caring about the output.

Yea, but its a pain to open another tab and run another command and switch back to this tab to see the progress.

Why they didn't give a progress bar in the first place beats me.

progress(1) is a separate utility on BSD; one of my favorites. (Although it is also built in to BSD ftp.)

I regularly use progress with dd, tar and other utilities.

At least one BSD dd now has a "msgfmt" option that outputs parseable, printf-style format strings.

Truthfully, I prefer it when these basic utilities are static except for fixing bugs. Using the new features in scripts means the scripts might lose some portability.

There's also the pv(1) utility on Linux and OS X Homebrew:

  DESCRIPTION
  
       pv  shows the progress of data through a pipeline by giving infor-
       mation such as time elapsed, percentage completed  (with  progress
       bar), current throughput rate, total data transferred, and ETA.

       To use it, insert it in a pipeline between two processes, with the
       appropriate options.  Its standard input will be passed through to
       its  standard output and progress will be shown on standard error.

(edit: formatting)

I use this often on OS X :)
