New to Ruby. Why does the command line pop up an then go awa

When ever I run a code file .rb

The code,

puts "Hello"

I get the command prompt that flashes for a moment but does not stay up.

How do I fix this.

On windows there are two ruby executables: ruby.exe and rubyw.exe. read about them here:

If you want to ruby console output run the script from a shell instead of double clicking:

C:\Users\me\Desktop>ruby test.rb
Hello

or use irb:

C:\Users\me\Desktop>irb
irb(main):001:0> load "test.rb"
Hello
=> true
irb(main):002:0>

This is not as correct as the other approaches, but you can also end
your code with "getc" then the program will pause until you press enter.

Hi John,

no harm meant indeed.

Unless you tweak "termios". What cannot be done on Windows...

Did ever anyone count the unnecessary and dulling questions
that arise by just running that wicked OS?

Sorry, sorry, sorry. I cannot resist posting the truism. A score
of times I refrained.

Essentially, your program does what you tell it: open a console window,
run the program, close the console window. Because running your program
takes only a microsecond, you see the console flash open and shut.

Sigh... "getc" is sorta deprecated. Use "gets" or "STDIN.getc" if you
get a warning with "getc". (I guess it was even less correct than I
thought ;-D )
