Regular expression does not detect End of Line

[AndyS01]

I want to remove all characters in a string, from an Asterisk to the end of the string, but the End Of Line regular expression character ('$') does not work for me.

$pat =  "[*]$"
consolewrite("+++: " &  StringRegExpReplace("D:\Temp\File.txt * 2abc def" ,$pat, "") & @CRLF
$pat =  "[*]"
consolewrite("+++: " &  StringRegExpReplace("D:\Temp\File.txt * 2abc def" ,$pat, "") & @CRLF

results in:
+++:  D:\Temp\File.txt * 2abc def
+++:  D:\Temp\File.txt  2abc def

I expected the first result to be: "+++: D:\Temp\File.txt "

(The second result just removed the Asterisk, as I expected.)

I tried \z and \Z, but they didn't work either.

You need the m (multiline) modifier.

"(?m)\*.*$"

Thanks for the example.

My problem was that my expression said look for an Asterisk AT the end of the line:

"[*]$"

What I need was an expression that said look for an Asterisk followed by zero or more characters up to the end of the line:

"[*].*$"

Correct, I think I was confused because you also mentioned EOL.

With the (?m) modifier it will match any line ending, without the flag it matches the end of the string just like z.

You could also write it like this:

*.*

which will match the first * it encounters and anything after it, and since this match is gready that means it will match to the end of the string.

Thank you. I'll use it that way from now on.
