Third Replicator,
If you are using some Linux system then you are safe. I use Ubuntu myself. I was tied of rewriting everything I put on the console too. So I with some little effort and help from friends, I made a small hack. Now, I have a simple script that helps me keep track of command-line history for both irb and script/console.
Follow the steps below:

So I with some little effort and help from friends, I made a small hack. Now, I have a simple script that helps me keep track of command-line history for both irb and script/console.
Follow the steps below:
- create .irbrc file in your home directory :
ceekays@kanjedza:~$ touch .irbrc
- open .irbrc using your preferred text editor (I prefer command-line based ones: vi, vim, gvim), add the following lines and save:
# This script saves and retrieves up to 600 lines of
# command-line history in both irb and script/console
# of a Rails's project. (UP and DOWN ARROW keys to navigate)
# In addition, it supports auto-completion.(Use the
# TAB key to get auto-complete suggestions).
#
# :SAVE_HISTORY keeps the maximum number of lines to be saved
# customize this to suite the amount of history would
# like to retrieve
#
# :HISTORY_FILE keeps the file name where the
# history is kept. In this case it is saved in the
# home directory of the current user
# i.e in the same directory where as this .irbrc file
ARGV.concat [ "--readline", "--prompt-mode", "simple" ]
require 'irb/completion'
require 'irb/ext/save-history'
require 'rubygems'
require 'map_by_method'
require 'wirble'
require 'pp'
IRB.conf[:AUTO_INDENT]= true
IRB.conf[:SAVE_HISTORY] = 600
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history"
Wirble.init
Wirble.colorize
# command-line history in both irb and script/console
# of a Rails's project. (UP and DOWN ARROW keys to navigate)
# In addition, it supports auto-completion.(Use the
# TAB key to get auto-complete suggestions).
#
# :SAVE_HISTORY keeps the maximum number of lines to be saved
# customize this to suite the amount of history would

#
# :HISTORY_FILE keeps the file name where the
# history is kept. In this case it is saved in the
# home directory of the current user
# i.e in the same directory where as this .irbrc file
ARGV.concat [ "--readline", "--prompt-mode", "simple" ]
require 'irb/completion'
require 'irb/ext/save-history'
require 'rubygems'
require 'map_by_method'
require 'wirble'
require 'pp'
IRB.conf[:AUTO_INDENT]= true
IRB.conf[:SAVE_HISTORY] = 600
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history"
Wirble.init
Wirble.colorize
Once you have this, you will be able to retrieve script/console's command-line history up to 600 lines. Please inform me if doesn't work. I would be very happy to get as much input as possible.
I think Sprite will also find this useful.
P/S: I am not sure if I have violated the forum rules by adding an attachment. If so, forgive me and inform me how best I can send files through.
Regards,

When you quit script/console you lose your command history. What
would it take to get get that command history to persist? I wouldn't
mind working on it if somebody had a good suggestion as to how to
achieve that and if it was an acceptable solution to the core team.
Cheers,
