Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

nice one! i'm kind of a noob so how can i print the output into a text file, with one line per result?

Just use output redirection (a ">" and the filename):

[hiswholecommand] > otuput.txt

What's the advantage of the above over

find -regextype egrep -type f -iregex '.*\.(avi|mpg|mov|flv|wmv|asf|mpeg|m4v|divx|mp4|mkv)$' -print0 | sort -z | tr '\0' '\n'

(using gnu find).

Also - the part of "-print0..." and to the end of the line is only necessary if you care to sort the files by name.

Another thing is that if you don't specify "-f" to "ls -1" then ls will re-sort the file names. Maybe that's another point in favour of using the "tr" instead of "ls" to convert the \0's to newlines.

ls -1 is being called on a per-item basis here so it wouldn't resort them. not sure if tr or ls would be faster but you could save yourself a bit of headache by killing the -print0, -z, and tr like this

find -regextype egrep -type f -iregex '.*\.(avi|mpg|mov|flv|wmv|asf|mpeg|m4v|divx|mp4|mkv)$' | sort

good call on the find iregex though.
