Try placing the code in a file called ~/.irbrc

$ cat ~/.irbrc
IRB.conf[:SAVE_HISTORY] = 1000

At…
Linux 2.6.32-27-generic #49-Ubuntu SMP x86_64 GNU/Linux
Using system ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]

The ~/.irbrc worked and the history file is called ~/.irb_history #
with underline

But using rvm 1.1.8
and… ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-linux]

At the file
~/.rvm/scripts/irbrc.rb

around line 27 you have

Kernel::at_exit do
maxhistsize = 100
histfile = File::expand_path(".irb-history", ENV[“HOME”])

I changed the maxhistsize to another value and it worked.
But the history file is .irb-history (with hyphen)

This is probably related to the advice at line 14

Use an alternate way to on history saving until save-history is

fixed.

Thank you, this worked too for me.
Happy New Year!
