In Xcode, right click on the executable and then select Show in Finder.

Great video!
So now I know how to execute a program in Terminal.
How do I use it as a command-line tool? ex. cd, dir, chmod.
Do I just put it in /bin ?
Is there some kind of list to modify to notify bash that it's a command?

the way you say "forty-one" it sounds like you're a Dave Matthews Band fan.

great tuts, thanks.

@MrSmaq7777 To be honest I have never tried C# in Mac OS. I think your only options are either to use Windows, which may be better anyways. Or use Mono - just google Mono for Mac.

What’s the name of the “%s” thing? Is there a list of all of them?

Hello, Thanks for the video! just wanted to ask  a question. everything works really well until I change my program, then the command line on terminal still runs my old code not the updated one, Do you know how i can fix this?
Thanks in advance

Hi everybody!

Just want to add to a great tutorial an one thing:

You can run you program by Terminal (console app) within Xcode by clicking "Product"->Scheme->Edit scheme or just click Cmd+<. Then click Run->Options and scroll to the bottom and change radio button "Use Xcode" to "Use Terminal". Then you can run your program by Terminal.

awesome tutorial.I only have one question, how would you make argv accept a file. I tried putting the file name dot extension and the file name only but it keeps accepting it as a string instead of a file. Could you tell me how to force it to accept the parameter as a file. Thanks in advance

I believe if you move it to /usr/local/bin it should work correctly, but I'm not 100% sure.

If the output of the last Terminal command shifts the prompt, I instinctively hit Return without typing anything generate a new prompt which is properly placed before typing in a new command.

please help me find Executable in Xcode 4.2.1..

Since Xcode has been updated how to I get to executables?

[ctutorial]

gcc -S program.c
Running gcc like that will produce a file called program.s - thats your assembly output
