Does `go run file.go` Compile or Interpret, and How Does It Work?

Understanding "go run file.go": Compilation or Interpretation?

Unlike go build and go install which compile files into binary executables, the go run command performs a different task. It's designed to both compile and execute the specified Go file in a single step.

Essentially, go run file.go behaves similarly to running the following two commands sequentially:

go build file.go -o /tmp/random-tmp-folder/exe
/tmp/random-tmp-folder/exe

This operation involves the following steps:

1. The go compiler compiles the file.go file and generates a temporary executable file in a randomly named directory, such as /tmp/random-tmp-folder/exe.
2. The operating system immediately executes the generated executable, effectively running the compiled Go program.

By performing both compilation and execution in one step, go run provides a convenient and efficient way to quickly test and run Go programs without explicitly building and installing them as binaries.
