Online Upper Case Converter

I've tried using the uppercase filter but it does not work. I've tried doing it two ways:

<input type="text" ng-model="test" uppercase/>

and

<input type="text" ng-model="{{test | uppercase}}"/>

The 2nd triggers a javascript error:

Syntax Error: Token 'test' is unexpected, expecting [:]

I want the text to be forced to uppercase as the user types in the textbox.

How can I do that?

Is there a way in bash to convert a string into a lower case string?

For example, if I have:

a="Hi all"

I want to convert it to:

"hi all"

In one of my interview, the interviewer asked me why the upper case letters are before the lower case letters in ASCII table, I searched on google.com but found nothing, could anyone gave me the answer? Thx a lot!

I'm working with a designer, and we have a few different typefaces involved in the project - sometimes doing everything in all caps, sometimes all lower case. This applies to both my labels and buttons. These may change, so what I'm attempting to do is have custom UILabel and UIButton classes where the button title will be automatically adjusted to the case I want without regards to what capitalization is entered in the interface builder or text from code. I have successfully managed this with my custom labels with the following code:

class MyHeadlineLabel : UILabel {override func didMoveToWindow() {    self.text = self.text?.lowercased()    self.font = MyFonts.headlineFont}}

However, adding similar code to the didMoveToWindow() function of UIButton does NOT work:

class MyDarkTextButton: UIButton {override func didMoveToWindow() {    self.titleLabel?.text = self.titleLabel?.text?.uppercased()    self.font = MyFonts.subHeadFont            }}

How would I go about doing that? Or, better yet, is there a way to use my custom labels as the button labels?

I am trying to find all string entries with a lowercase 'a' at index 0 followed by any uppercase at index 1. I've tried a few different ways but this is as close as I can get.I've searched the forums but cannot find anything that fits. Any pointers are greatly appreciated.

Thanks
