[17:37] <_stink_> does anyone know if there's a way, in the linux filesystem, to have a node that is a transformed version of another node?
[17:38] <_stink_> for example, i have a log file. i want to have a second file that when i read it, contains just entries from the original log file that meet some regex
[17:39] <_stink_> kind of like a filtered, live view of the original file
[17:39] <_stink_> i've searched around but found nothing useful yet
[17:41] <_stink_> or maybe there's a long running grep-style thing...
[17:58] <cmaloney> I think you're looking for something like fuse for that
[17:58] <cmaloney> you'd need to write something to do that kind of a view though
[18:33] <jrwren> not at the filesystem level by default, but you could write a VFS that does it.
[18:33] <jrwren> since your original question was re: logfiles, you can get rsyslog to do it for you.
[18:34] <jrwren> but it isn't virtual at that point.
[19:53] <Scary_Guy> I'm pretty sure there is a grep command that would write that into a file which you could make a cron job.  Just can't call it too much or you might fill the partition.
[20:13] <jrwren> _stink_: oh! a BG process to a socket!  dammit... 
[20:13] <jrwren> !8ball should I write this for _stink_?
[20:13] <jrwren> lol
[20:43] <jrwren> hrm... it would be a little tricky on re-reads but _stink_ you said you like socat, right? :)
[20:44] <jrwren> although, at that point, might as well make it an http api. :p
[20:58] <_stink_> thanks for the ideas cmaloney jrwren Scary_Guy !
[20:59] <_stink_> the real application here is to simplify some already existing python code that reads a file and grabs the last line... i want it to only consider lines with a certain format
[21:00] <_stink_> so i was hoping to offload it to some ready baked tool
[21:00] <_stink_> but if it's a matter of writing a bg process or a VFS... i may as well just fix my python code :D
[21:52] <jrwren> TIL: eatmydata and it is installed by default in ubuntu-server. I've no idea why.
[22:09] <jrwren> anyone have ATT for data and think it is funny that they still use sbcglobal.com dns?
[22:10] <Scary_Guy> No but I know others who have it.
[22:17] <jrwren> second hop or so to AWS is 162-225-188-1.lightspeed.livnmi.sbcglobal.net for me, and it makes me laugh sometimes
[22:17] <jrwren> ATT bought SBC in 2005
