How to use Regex to match anything but a period and a comma

I'm trying to do a match on things such as thomas. - any string ends up with a period or a comma.  How should I do it?  Thanks.

Shouldn't I use the escape? I tried the following, but it doesn't work...

[^\.\,]+

Obviously: in regex: don't escape the dot inside of brackets [ ]. Never escape a comma.

If you want to match lines that end with a comma or period use

[,.]$

Within [ ], you don't need to escape except for \[ and \]

No, that is a character class. Did you try what I wrote exactly? What I wrote should do it. You can review character classes (and many other useful items) here.

While it doesn't hurt anything (typically) to do so, you don't have to escape those particular characters within a character class.

Within [ ], you don't need to escape except for \[ and \]
...and the hyphen, if it does not occur as the first or last character of the class   ; )

Another way might be:

my $s = 'Thomas.';

if ($s =~ m/(\.$)|(,$)/g) {
print "Found\n";
}
else {
print "Nope\n";
}

By "string" do you mean a single word, or an entire sentence, or a string?

Assuming you require a period or comma after the value you want, these might work for you:

If you want a single word:
\w+(?=[,.])

If you want a sentence:
[^.,?!]+(?=[,.])

If you want the entire string before the period or comma:
[^,]+(?=[,.])
