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 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.
