irb command line prefix remove

Question

I just updated my ruby version and now when I run irb in command line, I get this weird:

1.9.2p290 :001 >

every line. Before it was a simple >

How can I get it back again?

You can edit your ~/.irbrc file to change the prompt (command line prefix). See this answer for an example. You could put this in there to start:

IRB.conf[:PROMPT][:CUSTOM] = {:PROMPT_I => ">> "}
IRB.conf[:PROMPT_MODE] = :CUSTOM
IRB.conf[:AUTO_INDENT] = true

.irbrc is a Ruby script that irb runs when it starts up that lets you configure your prompt.

Note that this doesn't work in 2.3. `NoMethodError: undefined method 'write' for nil:NilClass`. See the answer by @user1179942 – Eric Haynes Nov 12 '16 at 15:41

From this article, in your user dir ~/, create the .irbrc file with following:

IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
  :PROMPT_I => ">",          # normal prompt
  :PROMPT_S => nil,          # prompt for continuated strings
  :PROMPT_C => nil,          # prompt for continuated statement
  :RETURN => "=> %s\n"       # format to return value
}
IRB.conf[:PROMPT_MODE] = :MY_PROMPT
