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.

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]*

Any time I want to use ruby's ri tool, (e.g. after typing something like ri GC), after it shows the documentation, I can find no way of exiting it and none of the usual key combinations for terminating a command-line command works. Because of that I'm forced to close the whole terminal window to continue my works.
How can I quit normally from ri after it showed documentation?
The answer is to simply type q and it will exit.

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.

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.

another regex which does the same as "diff.*\n.*\n.*\n.*\n.*\n " [closed]

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}/
