How to move some files but preserve the directory tree?

Posted on by

So, I have a bunch of ogg files that I moved to mp3 (I don’t want to start a format/encoder war, I just did it), I wanted to move the old ogg files, I didn’t delete them because probably I need them in the future. To move the files apart the easiest way could be using find and xargs:


find . -iname "*ogg" -print0 |xargs -0 -I {} mv {} /dest/folder/

The problem with this is that all those ogg files would be in /dest/folder/ all together, and I want to have them each in the corresponding subfolder, I was looking and found that some uses “cp –parents” unfortunately it seems that the cp in OS X does not include that.

What I ended up doing.

If you create a package file (.tar for example), the directories are preserved, so, for me the trick was using tar for that purpose.


find . -name "*ogg" -print0 | xargs -0 tar cvf - |(cd /dest/folder/ ; tar xfp -)

You’ll see all those ogg files in the screen as they are “copied” to the destination folder. later you can remove the files with find again.


find . -iname "*ogg" -delete

 

I assume there is a way to remove the files as soon as they have been added to the tar file.

TripMode

Just a small post about TripMode a small app (and kernel extension) that helps a lot to control which program is having access to internet, not only incoming connections but more importantly outgoing when you are on a limited connection.

Since a little more than a month I’ve moved to a place where the internet connection was not that good. I used do have 20Mb/s connection and was working perfectly fine, but when I moved here.. well.. the internet was pretty unstable and the bandwidth was like with dial-up modems.

TripMode help me a lot to let some applications use internet, example, Chrome, iTerm, SSH, and some other command line programs, but forbid others like App Store, Updates, the Photos Agent, Dropbox, etc.. of course I can allow any of them whenever I want/need. This to allow all the important apps to have internet, the most possible bandwidth. 

That was in the small town where I was a week ago, then one week I didn’t have a landline and I had to use my cellphone internet, which is fast but is expensive, and TripMode helped to limit the internet usage, so I didn’t finish my cellphone’s credit. This was awesome

Note this is not a paid post, I just like this app and deserves my recommendation.

I’m getting used to this

I know I said 3D touch is not the thing, but is handy. Of course, I’m used to the usual way to do things (entering to the app and then hit the action button) and I expect the apps really make use of this technology, I hope.

And talking about the device, It’s great, as you can see in my flickr photostream I’ve been using it for a couple of weeks now, pictures are great although with the bandwidth I have here (near to Guatemala) is hard to upload several pictures, not to mention videos. But pictures are fine, about 2MB in size and look definitively great (I still want my DSLR camera). In terms of performance, you can watch several videos about the 6S performance in youtube. Its also great, reloading apps happens not to often, sometimes it’s barely noticeable, sometimes it is but almost all time you won’t notice.

Apple, Why U NO Let me use your extension in Chrome?

Apple have this chrome extension so you can sync your Safari favourites with Chrome, but it is designed to run on Windows 7/8, bad luck for those that use OS X and prefer to use Chrome.

I also use Safari, but for my day to day I use chrome because of the extensions. If Safari could add good extensions that would be great!

Is 3D Touch really a thing ?

Posted on by

  
I don’t think so.

I mean, to me is definitively not something that really changes the way you interact with your phone, well, it does if your interaction is with an iPhone, but in android we have something similar, the long press witch helps you to achieve the exact same thing. 

There are some other gestures like the double tap and swipe up/down in chrome to zoom in and out. So for me not something that useful, new yes, valuable yes,  useful yes, the thing…. No.

Modify preferences using Alfred+OsaScript

Posted on by

Since I start using OS X I’ve never been a “spotlight” user. Althought it is there and never really used it as my daily driver, for some time I used QuickSilver because when I was using Linux I used GNOME do, but then I switched to Alfred. The main reason is that is super fast and let me execute custom commands from a couple of key strokes.

Saving the fighting bull

Posted on by

  
In Mexico more and more states are making illegal the bullfight, but the Spanish bullfighting in which the bull is killed and mutilated if it was good for the show.

I do condemn that kind of events just because there’s animal abuse. Many people call it an “art” but there’s not any that could be it. First because even when the fighting bull is aggressive by instinct it’s not a reason to kill it. Lions are aggressive, hippos are aggressive and killing one is not allowed in many places, you need a specific permission and to be in the season to do it by sport (and I disagree killing animals by sport), not by mere art. 

 
Some people states that those animals exists because of that show, if the show ends then they are doomed to extinction. So be it. To me it’s preferable that a specie became extinct instead of making them reproduce to kill them in a show.

But I’m pretty sure that even if the bull fights became illegal in the whole world that race of Bulls will not be erased fro the earth. I mean, there are lots of species that are in risk of extinction and there are efforts to preserve them, being in natural conditions or in a zoo. 

I’m pretty happy that in Mexico that kind of shows are getting forbidden.

Now what about the use of animals for our meals… I think that’s cruel too. We need to get the nutrition and flavor from somewhere else. I hope projects like “Soylent” become more and more popular and allows us to forget about killing animals for meat. Also, help places where food is scarce.

What do you think about bull fighting ?. Let me know in the comments.

Deleting old time machine backups

Posted on by

Time machine is one of those great thing that OS X have, it have saved me from reinstalling everything by hand when I experiment with my computer, making a full backup (including system, applications, configurations, etc..) helps me to erase the SSD whenever I want without worrying me about missing files. Even if you don’t want to erase your hard drive, maybe it just died, having a backup will have your system in the same way it was, just like if nothing ever happened.

But, also, Time Machine is a space consuming thing, because we create a lot of files, most of them gets backed up (for instance, I don’t backup the Download folder or the virtual machines) and when you upgrade your system a big backup is made. So, it’s easy to fill a disk

I have a 1.5 TB HDD for backups, and my backups are from april 2013, I don’t really think I need something from that far,I don’t even remember what was in my computer that time. Deleting those backups can give to me some free space. At the end Time Machine will delete those old backps when the space is out.

 

So, to start, I want to delete all my backups from 2013. I can use “tmutil delete” to delete them, so, lets find which ones are about to be deleted.

Now that we now which ones are going to be removed, just call “tmutil delete” to delete them.

I just hope everything go fine 😀
