In order to see a list of folders with sizes you can use the du command. To make the sizes human readable use the -h option To make sum the size of child folders use the -s option (may take some time to run depending on the contents). du -hs * Here is an (uninteresting) example of the output. 0B Desktop 632K Documents 356K Downloads 76M ...

Your guess was correct. .ipa stands for iOS App Store Package Each .ipa file is compressed with a binary for the ARM architecture that can only be installed on iOS devices. If you change the extension to .zip you will be able to unzip it and view the contents.

Your frustration with the Finder is a worldwide sport :) Finder does make things harder sometimes. Finder exhibits different behavior depending upon the context (both the source and destination) of your files. If you drag files in the same "Volume" (or Drive), it will default to Move. If you drag files to a different "Volume" (or Drive), it will ...

Basically, it tells an app opening the file to open a copy. You do this on files that you want to use like templates. Since the app is given a copy, you'll never accidentally change the original. Basically, it automatically copies the file into its original location (as 'name copy') and lets you work on the copy.

Yes. Apps are installed to the usual /Applications folder. Non-admin users can browse the store, but they will need an admin username/password to install apps.

We (the OS X users) have been asking ourselves that question since the age of dawn. Very well phrased question to a sad response: OS X doesn’t do that and can’t do it without 3rd party tools. Of the 3rd party alternatives there are a lot, I’ll just go ahead and recommend what I think it’s the best alternative to Finder, but… your mileage may vary. Path ...

The + indicates the file has an Access Control List (ACL) with additional permissions. Each rule in an ACL is called an Access Control Entry (ACE). The command ls -ale will show the ACEs for each file/folder that has an ACL The default folders OS X creates when it makes a new home folder — Desktop, Documents, Downloads, Library, Movies, Music, Pictures, ...

In a nutshell, yes, this behaviour is expected. It's less than ideal but it's completely explainable and it's a biproduct of how files and directories are represented on the filesystem level. It helps to understand how files and directories are represented on the underlying filesystem via inodes. And how moving a file on the same filesystem doesn't actually ...

You can put the file into an encrypted disk image. Open "/Applications/Utilities/Disk Utility" File > New > New Blank Image... In the new image dialog make sure to choose: Encryption = 128 or 256-bit AES Image Format = read/write disk image Because you chose encryption, you will be prompted to set a password for the disk image You now have a ...

The problem: .itmsp folders are shown as files The Finder treats .itmsp folders as packages, that is, as if they were a single file. For example, in column view, anything contained within the .itmsp folder is invisible, only the document icon is shown: The Finder considers a directory to be a package if any of the following conditions is true (from the ...

It is possible to cut-paste files/folders in OSX 10.7 Lion's Finder (so, since 2011), but the OSX way is slightly different from the Windows way. ⌘-C (copy first) ⌘-⌥-V (now move to it's destination) So, the steps are very similar to copy-paste, but holding ⌥ (option key) moves the file/folder instead of copies it. You can also have a look in the edit ...

As an alternative to deleting them, you could consider hiding them in the Finder instead. To do this, launch Terminal then enter this command: chflags hidden ~/Public ~/Sites If you ever want to make them visible again, you would use this command: chflags nohidden ~/Public ~/Sites

One option would be to unregister Application Loader with lsregister -u /Applications/Xcode.app/Contents/Applications/Application\ Loader.app/, but it is registered again if it is opened, if the Launch Services database is rebuilt, or possibly if Xcode is updated. You could also comment out the entries in the CFBundleDocumentTypes and ...

There are two ways I do this (and the info window is neither of them): Open the Terminal application and drag the item into the window, and a POSIX-style path will be displayed that you can copy and paste. Use Applescript... ...select an item in the Finder and run this... tell application "Finder" return info for selection as alias end tell ...or ...

Those are extended attribute files, which OSX uses when the filesystem doesn't support resource forks or extended attributes. You don't care about them. (The entry you quoted is a message to the Finder to display a "This file was downloaded at (date). Downloaded programs may be unsafe. Do you want to open it?" dialog along with a button which will open ...

You can add a default application for public.plain-text in ~/Library/Preferences/com.apple.LaunchServices.plist. defaults write com.apple.LaunchServices LSHandlers -array-add '{LSHandlerContentType=public.plain-text;LSHandlerRoleAll=com.apple.textedit;}' '{LSHandlerContentType=public.unix-executable;LSHandlerRoleAll=com.apple.textedit;}' Restart to apply ...

The "Show all filename extensions" option overrides the "Hide extension" option in Get Info. This means that there are a few possible solutions one could try to find in order to hide ".app" extensions while showing the rest: Find a way to exclude certain extensions from "Show all filename extensions". Find a way to hide extensions, other than the "Hide ...

The primary place to look for unsaved changes for TextEdit is ~/Library/Containers/com.apple.TextEdit/Data/Library/Autosave Information/ It depends on the state of the document, and it is complicated (since unsaved changes could also exist once the file has been saved and named the first time). Unsaved documents The first type — the "behind the ...

From Apple’s Launch Services Programming Guide (all emphasis mine): All applications available on the user’s system must be registered to make them known to Launch Services and copy their document binding and other information into its database. It isn’t ordinarily necessary to perform this task explicitly, since a variety of utilities and services built ...

TotalFinder became a commercial solution not long ago: the full beta development stage was free and gave me plenty of time to test the software. It's an excellent solution, and I have seen almost every single bug disappear progressively. Even if not a free solution anymore, its source is available on GitHub. I would recommend it on the grounds that it ...

OS X does indeed have a home folder, in /Users/<username> with a hierarchy of folders, including one for Desktop, in this location - similar to Ubuntu. On most Linux distributions the /home is a different partition on the drive and formatting the primary OS partition would not erase your data. This is not the case with OS X and (unless you've made a ...

As already described by ayaz, the Get Info window (cmd+i) has the full path and will allow you to copy it. If you tripple click in the highlighted area (by the red rectangle) the selection will automatically expand to the whole path. cmd + c will suffice to copy it to the clipboard. If you need the path to interact with the Terminal, you can always check ...

Changes.app has a great reputation and lots of features. Kaleidoscope is great too, and has a beautifully designed UI. It's also worth mentioning if you're doing programming that Xcode 4 has visual diff tools built in now too.

According to Apple's developer documentation, any new documents that you haven't yet saved explicitly are autosaved in ~/Library/Autosave Information: Automatic document saving is supported by the implementation of autosaving in place. Autosaving in place and autosaving elsewhere both protect against the user losing work due to application crashes, ...

As Rabarberski says, lsof can be used to find any process that has the file open. Note that you need to run the program as root, i.e., using sudo, and that you can give the pathname to the file you're interested in as an argument, so there is no need for the grep invocation in the hint that Rabarberski points to. Also, if a process holds a lock on the file, ...

The difference of 1650 bytes is probably the result of the resource fork being stripped from the uploaded disk image. To test, I created a disk image from a folder in Disk Utility. I then used ls -l@ in the folder that contained the disk image, and it showed the image had a resource fork that was 1650 bytes.

Tab key to navigate the focus between buttons, and press the space bar when a button is selected. The effect is as above image. When a blue box around a button, press the space bar, the button will be "pressed". If you found that the focus cannot be set to the button, pen the Keyboard preference, and config it as following:

One possible reason for a different name is if the package has a localized name. This allows the name displayed in the Finder to vary depending on the language of the user, and it also can be different than the "actual" name of the file, as displayed in Terminal.

I understand your frustration, but I suggest you just hide the offending folders from Finder, you can easily do that with the following terminal command: chflags hidden ~/Documents/HideMe Preventing those folders to be created is likely going to cause problems running those applications.
