Can anyone tell me what is the difference between parse and foreach in CSV?
Check Ruby Document here.
Generally speaking, #parse is used to parse a string while #foreach is for a file.

I created an alias ll="ls -laF" and i have tried to use ll *[aeiou] [aeiou]*
and it just shows all the files that have two two files that have the letters aeiou in them. I also tried ll *[aeiou]* and i just get a listing of everything in a file again.
The ? matches a single character, so you're looking for
ls -laF ?[aeiou]*

Even though I'm using different ajaxUrl's. Like ajax01Url, ajax02Url, etc. Each one of them with its own typeNum. I keep getting the same array content in function(data).
Any suggestions how to clean this?
It was my own fault, I had a typo on the action name :)
I was calling the two different uri.action with the same name. Even though they have different pageType.

I have this regex:
diff.\*\n.\*\n.\*\n.\*\n.\*\n
I want to match everything from the word "diff" to the fifth new line. Can someone simplify it for me?
You need grouping:
diff(?:.*\n){5}
I think you are asking for this:
/diff(.*\n){5}/

I noticed in the Cell > Cell properties menu an item I assume was recently added, but I really wouldn't know for sure (8.0.4/Win here). It's called Initialization Command:
Nothing about it to be found in my documentation center. Neither does it seem to be in the online reference:
Any idea what this is supposed to do? As far as I can see its effect is the same as the Initialization Cell menu item.

Trying to debug what may be a require/load problem in my environment (just printing $" & $: was not enough) I was hoping to wrap the load method, but my expected print statements do not execute, so I assume that the following did not work as I had hoped
module Kernel
alias :old_load :load
def load(fname, wrap=false)
puts "loading #{fname}"
old_load fname, wrap
end
end
So is it generally possible to wrap kernel methods (using aliases or otherwise)? If so whats would be the right syntax?
Thanks
