I know this thread is a couple weeks old but I thought I'd clarify a few points for posterity.

As others have noted, the difference in the "cli" of MacOS X and other unix versions is no more than you would see between say solaris and NetBSD.

OSX's preferred filesystem (HFS+) is indeed case insensitive. It is also case preserving. You do have the option of using UFS instead but it isnt recommended. I suspect we will see a new OSX filesystem in the next year or so. Nevertheless, it takes no getting used to. Unless you have a driectory full of files whose only name difference is case (file File fIle and so on) then you never notice it. ls is still ls... and other commands work as expected grep FILE and grep file are NOT the same.

An "app" in OSX is usually either a carbon or cocoa GUI application. Carbon apps are legacy applications with minimal code changes to run under OSX (MSOffice, Adobe products etc...). Cocoa apps are ObjectiveC or Java applications that use the native ObjectiveC based frameworks derived from NeXT.

Carbon apps will likely never run on another unix, you would basically have to rewrite the whole thing. Cocoa apps can be ported to other OS's running GNUStep. In theory, this is easy, in practice it is not usually trivial.

talagent

TALAGENT(8)						    BSD System Manager's Manual 					       TALAGENT(8)

NAME

     talagent -- helper agent for the Transparent App Lifecycle feature.

SYNOPSIS

     talagent [command [arguments]]

DESCRIPTION

     The talagent daemon provides services related to the Transparent App Lifecycle feature.  talagent may also be run manually as a command line
     tool to output information about persistent state.

     The options are as follows:

     -help
	 Outputs usage information.

     -dump bundle_id_fragment
	 Outputs the persistent state of an application whose bundle ID contains the given fragment, case insensitive ("textedit" for example).
	 You may also pass a path directly to the app's persistent state directory, usually in ~/Library/Saved Application State.

     -launch bundle_id
	 This launches an app (in this case, TextEdit) in a manner approximating how apps get launched at login. You can pass either a bundle ID
	 fragment or a path to an app.	The app is maintained stopped until you hit return in the launching window (or until it receives SIGCONT).
	 This is the easiest way to test the login scenario without needing to log in.

     -casinfo [ASN]
	 With no arguments, outputs summary information about all apps. With one argument (an ASN), outputs the CAS record for that app.

     -memory_pressure
	 Simulates memory pressure, which may cause apps that support automatic termination to exit. This does not actually allocate any memory.

     -refresh_encryption
	 Rotates the bitmap encryption key, and attempts to cross-encrypt all existing window bitmaps under the new key. This is done periodically
	 by talagent.
