Regex to remove charaters

[uniopp]

Hi,
I've been trying to find a regex that will remove all the character from my string after a specified point.
$string="some_thing";
I would like to remove the "_" and everything after it.
The string will be of varying length but the cut off point will always be the "_" character.
How can I do this?
In addition if the string contained more than one instance of the "_" character, how could I get it to cut off at the first one?
Thank you.

You could use a regex like this:

s/_.*$//;
[code]
but you might ilke to consider the substr and index solution:
[code]
substr($_,index($_,"_")) = "";

Personally I prefer the regex but I'm sure you'll find many here that prefer the substr.

Thank you.
I will use the regex at this stage to keep everything in my script the same (and it's easier for me to understand).
