Thanks, I meant to mention that, too. POSIX has "+" formats, but apparently no way to get an integer number of seconds. I don't know how widely "%s" is supported; BSD "date" seems to know about it.

Yeah, that would probably be a good solution, assuming there is a portable "how many seconds" (I do not relish the thought of reconstructing it based on the current hours/minutes/seconds).

I wonder how awful it would be to make a tool like "git-progress", where you'd tell it "--total=$commits --eta" on the command line, and then occasionally print the current count its stdin. It might be a little painful to use, though. You'd want to background it with a pipe to its stdin, which is annoying without bash-style "<()" anonymous pipes.
