I wanted to write about this as I learnt it recently. But Bharathi has already done it.
http://bharathi.posterous.com/one-day-one-gnulinux-command-pv simple usage: $ pv foo.iso | sha1sum It shows ETA, percentage and time elapsed and many other things. I use it in my ISO installer to show the progress of installation. Since I use Perl nCurses I wanted a tool to show progress with my own interface but data should come from elsewhere in the backend. pv has a -n switch which gave me just the percentage, so I used it and got my job done. I was very happy. ;) -Girish -- Gayatri Hitech http://gayatri-hitech.com _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
