Add a semi-colon (;) at the end of each line of text with RegEx

I am trying to add a semi-colon (;) at the end of each line of text in a file with many lines.   I want to use Regular Expressions to do it as I use UltraEdit editor (WindowsXP) which allows me to do a Search & Replace using Unix Regular Expressions.   If I use "$" it looks like it affects the carriage return (it puts a block instead of a ";" on every other line and a ";" at the beginning & end of every other line).

If I use ".$", it picks the last character instead of putting it at the end of the line (I would expect this).

How can I put a semi-colon at the end of each line?  Thank you for your help!

Thank you for your efforts, but I can't get what you offered to work.

I would prefer to use utilities like "sed", etc.   The files I want to manipulate are in WindowsXP.  I've tried using the GNU Utilities for Windows, but they are unreliable (I can't get the "$" to work consistently).  And I don't want to use an emulator like Cgywin.

What I am therefore trying to use is the text editor UltraEdit. It allows me to use Unix Regular Expressions, but it has both search and replace boxes (like Microsoft Word), so I can't use things like "sed".  What I'm trying to do is find how I can get to the end of the line to add the semi-colon.  If I can't do it here, is there another way to do it?

Well, I got it to work.  UltraEdit is a little different.

In the Find box I put  (.+)$
In the Replace box I put  \1;

That put a semi-colon at the end of each line.  Sweet!

You two are the only ones who attempted to assist me and I appreciate it!   I am splitting the points between you.  Thank you!
Regexes implementations vary a bit, so what might work for one language/platform may not work for another.

I must admit, I'm not sure why you are reluctant to run cygwin, if you are happy to install GNU Utilities for Windows.

I find cygwin is such a valuable tool on all my Windows boxes.
