Shows you how many hours of avi video you have.

/usr/share/mplayer/ `find . -name "*.avi" -print` | grep ID_LENGTH | awk -F "=" '{sum += $2} END {print sum/60/60; print "hours"}' is part of mplayer, but you might have to locate it on your box.

What Others Think

This seems to work a bit more reliably for me and finds other types of files. Plus, you don't need that grep. find . \( -name "*.flv" -o -name "*.avi" -o -name "*.ogm" -o -name "*.wmv" -o -name "*.mpg" \) -exec /usr/share/mplayer/ {} \;|awk -F= '/ID_LENGTH/{sum+=$2}END{print sum/3600,"hours"}'

It's interesting that that's more reliable. I wonder why that is. It's certainly nice to get rid of the unnecessary grep. If you want to find multiple file types, I'd suggest considering using find's -iregex find . -iregex '.*\(avi\|swf\|wmv\|mpg\|ogm\)' I think that'd make it easier to add/subtract file types. Also it'd be case insensitive.

That iregex is much better. I also modified the awk a bit to give hours, minutes, and seconds. find . -iregex '.*\(avi\|swf\|wmv\|mpg\|ogm\)' -exec /usr/share/mplayer/ {} +|awk -F= '/ID_LENGTH/{sum+=$2}END{a=sum/3600;m=(a-int(a))*60;s=(m-int(m))*60;printf "%s %.2d:%.2d:%.2d\n","Total time:",a,m,s}'

find -print0 | xargs -0 /usr/../midentify is waaaaaay more reliable than /usr/../midentify `find ` Command substitution has its uses. But pipes with xargs -0 is certainly more reliable!!
