2. Build and run the "file" program:

   • go run cmd/file/file.go

3. Build and run the "exec-subprocess" program:

   • go run cmd/exec-subprocess/exec-subprocess.go

   • It should output something like the following.

   • The 'ls' command found the following files in the current working directory:
     README.md
     cmd
     
     The 'docker' command reports the following version:

   • It should output something like the following.
