Running an Mac OS command line application, how to - objective-c

Suppose you create a new Mac OS Command Line Application using Xcode, which prints something. How do you actually find and run it using your command line or Finder?
Application was "built", but project directory structure does not seem to contain an executable file. For what matter in what format will this file be?
Please advise

This should help out:
Choose to build your project for archiving (Product->Build
For->Archiving).
The executable will be created and placed in the project build
folder. This will typically be something like
/Users//Library/Developer/XCode/DerivedData//Build/Products/Release.
If you wish, copy the executable to a more convenient location.
To run it, open up a shell window, browse to the executable
directory, and type in your command name.
EDIT
I see you mentioned iOS in your question and tagged it as such. This answer is NOT relevant to iOS, infact I see no option to build a command line application for that system and it doesn't really make much sense to have one.

Xcode "Building" a Project

Honestly, I don't fully understand my question, but hopefully I can still be fairly clear about it.
I just wrote a simple project in Objective-C/Xcode. It looks like Xcode generated an executable in a folder called "Debug" and when I double-click on it, it opens a terminal window and runs fine. However, while running, it reads from a text file in the same directory that it's in. So if I want move the executable to a different location, I also have to move the text file to the same location or it won't be able to find the text file.
My question is... when I download an application on my computer (like Google Chrome or Evernote), it comes as its own file and I can place it in any directory I like; there are no associated files I have to move whenever I move the "executable". Is there a way to generate a clean application like this using Xcode?

Can node webkit build in a single windows .exe file

I have a project that need to run in a pen drive, the content is updated daily, and i need a automated way to generate a single file (.exe) to be downloaded by users.
I use this tool https://github.com/mllrsohn/node-webkit-builder, but when build for windows, the build generate multiple files ( dlls, dat ,exe ).
This break my automation because the content need to be downloaded (single file).
Any help?
As far as I know, it can't. You could try making a 7zip SFX archive and running your own program instead of an installer.
This needs to create temporal files when run (which are deleted when the program quits) and I don't think you can remove the initial prompt. If you're okay with that, it might be what you need.
Edit: You can get the necessary SFX modules here.

How can I bundle a command line utility in os x application on Mac App Store (using sandbox entitlement)

I have a c++ command line application that I have already compiled into an executable and have added it into my Xcode project. I have also added the "Copy Files" section to the Build Phases tab of the project properties and added my executable with the "Executables" destination. When I build my application I see it in the test.app/Contents/MacOS folder when I View package contents on the test.app that is built.
I also have App Sandbox enabled on the Capabilities tab of the project (so that I can distribute my application through the mac app store.
How can I expose this command line executable that is bundled with my application to the user so that they can run it from the command line (terminal)? I have not been able to find anything on search engines or on StackOverflow about how to get this file (or a symlink to this file) into the users PATH. I tried using an NSTask to create a symlink, but that only works if I disable the App Sandbox (which makes sense). Has anyone done this before? How did you get it to work? Or can these executables only be executed by code within your application?
I don't see a good way to do this. First, a clarification: the PATH is a list of directories that contain executables, not a list of executables; there's no way to add a single executable to the PATH. Instead, what you'd need to do is either put your executable into one of the directories in the user's PATH, or add the directory your executable is in into the PATH.
On OS X, the default PATH is /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin. The first 4 directories shouldn't be modified from the system default, so only /usr/local/bin is a possibility. But creating it (it doesn't exist by default) would require admin (actually root) rights, which isn't allowed by App Store policies. So that's out.
That leaves modifying the user's PATH. The "right" way to do that system-wide is by placing a file in /etc/paths.d, which requires admin (/root) rights, so that's out too. Technically modifying the /etc/paths file would work, but that has the same permissions problem plus it's the wrong way to do customization.
The next possibility is to modify (/create) the user's shell initialization script(s). This'll work, but doing it at all right is going to be messy, because there are several shells the user might use, each with several different possible initialization scripts that the user might or might not have created...
Let's take a very simple case: a user who only ever uses bash, and who doesn't already have any initialization scripts. When a "login" instance of bash starts, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile (in that order), and runs the first one it finds. But your app doesn't know which shell he uses, so you'd better create ~/.profile so zsh and ksh will use it as well. So, your app creates ~/.profile, and puts this in it:
PATH="$PATH:/Applications/MyApp.app/Contents/Helpers"
Great, right? Yup, great, until the user runs something else that wants to set their PATH, it creates ~/.bash_profile, and this overrides your setup. After that, your executable will be in the PATH of zsh and ksh, but not bash. Whee.
And then one day the user decides to use tcsh instead, and it (and csh) have a completely different but equally messy pile of possible init files...

What does Main.1 output file do in XCode?

I made a sample project called "Stack", but realized that i needed some more data structures, so i renamed everything - the project, made 2 new folders & their matching groups in XCode, modified the Target Build path to look for "Main/DataStructures-Prefix.pch" instead. But there's one file i don't understand -> earlier, i had gotten a "Stack.1" in my folder, so i just renamed it to "Main.1" and it doesn't seem to be affecting the build process, but i'm pretty skeptical. What does this "Main.1" do? is it the linked intermediate file like in C/C++?
here's a picture:
"Main.1" is a template for creating a "man page" (i.e. an on-line manual page) for your program. You can verify that by calling
man ./Main.1
on the command line in the directory where "Main.1" is located.
If you run
xcodebuild install
on the command line then the manual page is copied to the
$DSTROOT/usr/share/man/man1/
directory, where DSTROOT is the "Installation Build Products Location". The file is not used otherwise in the build process.
If you don't need a man page, you can just remove the file from the Xcode project.

Build and Debug application outside the default package

If I try to build an application with the application class outside the default package, so the application file path is /app/AppClass.mxml instead of /AppClass.mxml (as would normally be the case), Flash builder cannot launch the application for debugging because it is looking for the SWF in debug/app/AppClass.swf and the SWF is being output to debug/AppClass.swf instead. Changing the output folder to debug/app makes it put the swf in debug/app, but then it puts the application configuration file "AppClass-app.xml" in /debug/app/app and then that can't be found.
Is there a way to change only the SWF output folder, or the location of the xml configuration file in the run-configuration?
You may use symbolic link to created swf file - http://en.wikipedia.org/wiki/Symbolic_link
for example for Windows :
cd project/path/bin-debug/package/path/
MKLINK ClassName.swf project/path/bin-debug/ClassName.swf
and it's work
or you can use symbolic link for folder:
cd project/path/bin-debug/package/
MKLINK path project/path/bin-debug/ /D
I think I remember this worked for me. But it was long time ago. And, yes, it is a known problem, I also recall Adobe people mentioning it as a limitation of FB.
In my Ant script, you'll need to do the adjustments to reflect your actual file names and directory structure. Also note that it will make it more cumbersome to debug it from FB. You'll need to use the debugging target in Ant, and then connect the debugger to the running application (so that some info, especially on the startup) will be lost. The only way you would be able to debug it, though I've never tried it, is with the commandline tools (I'm not sure of adl syntax for breakpoints / printing / stack frames, so idk how to do it.
Also, for the released application you will probably want to change the signing mechanism.
