Long story short, to make for example an executable file from a C file “.c”, use the terminal tool xcrun with clang as an argument followed by the name of your “.c” fileThis will look something like xcrun clang helloworld.c.

When you need to install software updates on your Mac, you probably head to the Mac App Store. Apple’s curated app store has long been the default method of not just finding and installing third party applications, but also of applying patches and updates for macOS and other Apple applications. But when it comes to macOS software updates, the Mac App Store is really just a front end for a UNIX command, and fans of the Mac’s Terminal can actually use this command to update their Mac and first party apps while bypassing the Mac App Store altogether.
The Mac software update command we’re talking about is helpfully well named: softwareupdate. Here’s how to use it.
Now that you know how to run the Mac Software Update from the Terminal, the likely question is why you’d want to use this method instead of simply clicking a few buttons in the Mac App Store. One big reason is automation and remote management. Users with multiple Macs to manage can create scripts or remotely initiate a software update via a method such as SSH without needing to manually use screen sharing or remote management software.
Another potential benefit is speed. While not universal, many users report that updates install faster when installed via Terminal, both in terms of the initial installation as well as the post-restart portion as the Mac reboots. While not every update will see a significant speed increase, the Terminal method at least won’t add any time compared to the Mac App Store.
Despite its benefits for many users, there’s one big caveat of running the Mac Software Update via the Terminal. As mentioned at the beginning of this article, the Terminal method only works with macOS system updates and first party Apple apps like iTunes. This is compared to the Mac App Store, which will update your third party apps alongside the official Apple updates.
Longtime Mac users may recognize this limitation is the same as the original Mac Software Update utility. This utility, which is how Apple delivered system and first party updates to users prior to the launch of the Mac App Store, did not support third party applications. Since the softwareupdate UNIX command also served as the basis of the original Software Update utility, this limitation makes sense.
So, if you only want to quickly install macOS system and first party updates, or if you don’t use any third party apps from the Mac App Store, the Terminal method has you covered. If not, you may be better off sticking with the default Mac App Store method as it keeps both your first and third party app updates all in one place.

This document instructs you on how to use the Mac OS X Terminal with Java.
You will use the Java compiler javac to compile your Java programs andthe Java interpreter java to run them.To verify that Apple's implementation of Java 2 Standard Edition (Java SE 6) isalready installed:
You will type commands in an application called the Terminal.
- To check that you are running the right version of Java, typethe commands in boldface below. You should see something similar to the information printed below. The importantpart is that it says 1.6 or 1.5 (and not 1.4).Then type
- Since you will be using the Terminal frequently, you may want tocustomize the default window settings (e.g., Monaco 13pt font with antialiasing).
You will use the javac command to convert your Java program into a form moreamenable for execution on a computer.
- Assuming the file, say HelloWorld.java is in the currentworking directory, type the javac command below to compile it.If everything went well, you should see no error messages.
You will use the java command to execute your program.
|Input and Output|
If your program gets stuck in an infinite loop, type Ctrl-c to break out.
If you are entering input from the keyboard, you can signifyto your program that there is no more data by typingCtrl-d for EOF (end of file).You should type this character on its own line.
When I try to run java I get: Exception in thread 'main' java.lang.NoClassDefFoundError.First, be sure that HelloWorld.class is in the current directory.Be sure to type java HelloWorld without a trailing .classor .java.If this was not your problem, it's possiblethat your CLASSPATH was set by some other program so that it no longerincludes the current working directory.Try running your program with the command line
I get the error 'class file has wrong version 50.0, should be 49.0' when I compilefrom the Terminal.
