Find large files on a Mac using Terminal

Every few days, I had an issue where my startup disk was full and emptying the trash just wasn’t doing enough.

I found the following command online that searches a file system for files over 500MB and prints the file path. It identified files I had totally forgotten about as well as some huge files generated by apps I no longer used.

sudo find / -size +500000 -print

I then used the rm command to delete files. When deleting entire directories I used the recursive flag (be careful!)
rm -rf <directory path>

Remove all .svn folders in subdirectory

You may want to copy the contents of one folder to another, but if the original folder is already added to Subversion (SVN) you get an error when committing the new folder.

When a folder is committed to SVN, a .svn folder is added to each folder within the folder subdirectory. To un-add the folder from SVN, you simply remove this .svn folder.

To save time, you can remove all .svn folders within the folder subdirectory by using the following command.

Mac OSX Shell Script to automate connecting to WiFi network

I have a Mac laptop running ‚Snow Leopard‘ that occasionally will not connect to my home WiFi, even though other devices are connected to the network just fine.

I wrote a small shell script that uses the networksetup command to reset AirPort. If WiFi is still not connected, the script tries to assign the AirPort WiFi network directly. If that doesn’t work, it just resets AirPort again.

Here is a good guide on how to exclude files and directories from SVN.

Serge Desmedt

Excluding files from your repository
Sometimes you may have types of files or folders in your source code tree that you do not want to include in your source code repository. Everyne developing with Visual Studio will immediately know what I mean: VS automatically makes bin and obj subfolders for your project folder in which it puts the buildresults and also creates *.suo files with your personal settings for a solution.

It would be convenient if we could exclude these files from our repository once and for all without having to manually uncheck them each time we update our project. Fortunatly, Subversion allows us to do this. In fact, there are two possibilities for exclusion.

Global exclude

With the global exclude we can exclude a certain type of file of being added to any repository to which a certain client connects. To do this, you must edit the Subversion „config“…

Uninstall and Remove Xcode Completely

If you are in a position where you want to remove the colossus that is Xcode, here is the terminal command to use.

sudo /Developer/Library/uninstall-devtools –mode=all

In my case, I was using migration assistant to migrate my applications and user account to a new laptop. My older laptop had an older version of Xcode that I didn’t want included in the migration and as it is so big, I didn’t want to take the chance.

Using Terminal Screen Command

This is a simple one. For some reason, every time I use the screen command in terminal, I forget the commands.

There are probably lots of cool reasons to use screen but I use it to run a script over a longish period. The advantage of screen is I can start the script in the screen instance and detach from it. I can close my laptop and return later to my terminal, open my screen and check the progress of the script. Also, you can run multiple instances of a script as each screen has its own process.

So the basic commands I use and tend to forget are… Weiterlesen „Using Terminal Screen Command“ →
