I've ran a search in ruby-talk but I couldn't find an
answer so...
Can I run a linux command inside a ruby program. Like
history
=> 63 history
history -d63
Thanks

You are probably looking for `` or Kernel#system.
for example: puts `ls /etc`

`history' is not a Linux "command", it is a Bash command.
What for do you need a command history when you're not on a
command line?

Since it is a Bash specific command why can't you just run a Bash
command file using `` or system commands? That command file can contain
the Bash specific invocaion commands in the first line or any other
language for that matter. I don't think it is a good idea to make your
client aware of the specificity of the called program.

If you're looking for a history inside of irb that you can play with, take a
look at something like
this<http://gilesbowkett.blogspot.com/2007/06/irbrc-modifications.html><http://gilesbowkett.blogspot.com/2007/06/irbrc-modifications.html>but
make sure you get his new
version <http://pastie.caboo.se/71790>, as I found a tiny bug in the old
one. Handy for getting all the history you've done inside irb, or even
writing it out to a file so you can make a script out of it, etc.

Whoa, I never saw this. Kinda wish you guys had let me know 
No
worries, though.
Thanks for the fixes. I needed to revisit this anyway, as there's some
other stuff that doesn't work. I'll contact you and Giles off-list
about integrating your changes.
