mojo run ile Çalıştırma

You have a saved hello.mojo file. To see it work, you launch it from your terminal with the mojo command. 🖥️

The simplest way to execute a file is mojo run followed by the file name. Mojo compiles and runs it in one step.

Open your terminal in the folder that holds the file, or give the full path. Otherwise Mojo cannot find hello.mojo to run.

After you press enter, Mojo prints the program's output right in the terminal. Your greeting appears on the next line.

You can often drop the word run and just pass the file: mojo hello.mojo does the same thing as mojo run.

Change the code, save, and run the command again to see new output. This quick loop is how you learn fast in Mojo.

If you have a typo, Mojo stops and prints an error with the line number. Read it, fix that line, and run once more.

mojo run expects your file to have a main function. Without one, it has nothing to start, and you get a clear error.

For a faster standalone program, mojo build creates an executable file you can run directly, without compiling each time.

Use run while learning and iterating, since it is one quick step. Reach for build when you want a finished binary to ship or reuse.

Write code, save the file, type mojo run, read the output. That short cycle is the core habit of every Mojo session.

You want to compile and execute hello.mojo in a single terminal step. Which command does that?

Use mojo run from the file's folder to compile and execute in one step, read the output, then edit and run again. 🎯
