I am not sure I follow this discussion but 'watch' command is awesome. We all know that cp command doesn't give any feedback on how much of data is copied. So to see the amount of data copied while copying around 45 GB of data, I used watch.
$watch du -s -BM 'target-file' This monitored the file size of my target-file. Thanks for the command. =) On Friday 30 November 2012 10:14 PM, Arun Khan wrote: > On Fri, Nov 30, 2012 at 8:02 PM, Girish Venkatachalam > <[email protected]> wrote: >> On Fri, Nov 30, 2012 at 5:21 PM, Guruprasad <[email protected]> wrote: >>> On Fri, Nov 30, 2012 at 4:35 PM, Girish Venkatachalam >>> <[email protected]> wrote: >>>> You have watch command. >>>> >>>> $ watch ls -ltr >>>> >>>> or you can get a clock with watch. >>>> >>>> Just think... >>> Doesn't this list the contents of a directory ordered by modified time >>> in reverse order?
