nginx rewrite regex matching first group instead of all

I'm working on an nginx rewrite rule to redirect:
/collections/collection-name/products/product-handle-with-dashes
to:
/products/product-handle-with-dashes
I've got it almost working, the only issue I have right now if my rule to match the product handle is only returning the first string before the first hyphen.
My rule:
rewrite ^(/collections/.*)/products/(\w+)\.?.*$ /products/$2 permanent;
With this rule if I hit the following path: /collections/collection-name/products/some-product-handle it will redirect me to /products/some
what am I missing on my regex to allow it my second variable to capture the entire handle with dashes.

\w metacharacter of the PCRE/PCRE2 regex patterns include characters from ranges a-z, A-Z, 0-9 and underscore. It does not include a hyphen. You probably want [-\w] instead. The whole rewrite rule can be the
rewrite ^/collections/[^/]+(/products/[-\w]+)(\.\w+)?$ $1 permanent;

Nginx redirect rule with arabic characters

I need to create an Nginx rule that redirects /ae/ar/أسافر%20من%20أجل/ to /ae/en. I've tried with these two rules:
rewrite (?i)^/ae/ar/أسافر%20من%20أجل(.*)$ http://$host/ae/en? permanent;
rewrite (?i)^/ae/ar/%D8%A3%D8%B3%D8%A7%D9%81%D8%B1%20%D9%85%D9%86%20%D8%A3%D8%AC%D9%84(.*)$ https://$host/ae/en? permanent;
But no one worked. Looks like the rule is ignored, any clues to make this rule work properly?
Thanks in advance!

Rewrite does not see the percent encoded characters. You should be able to leave the arabic characters as they are (UTF-8 characters within the configuration file) and replace the %20 with a single space. The entire regular expression should be surrounded with "s.
Alternatively, use a location statement:
location = "/ae/ar/أسافر من أجل/" { return 301 /ae/en; }

Nginx How to rewrite a path ending with a .jpg extension

How to rewrite a path ending with a .jpg extension
from https://example.com/something/something/image.jpg
or https://example.com/something/something/something/something/image.jpg
to
https://example.com/image.jpg
but do not rewrite https://example.com/image.jpg

You can use the character class [^/] to match any character that is not a /.
Any URI that contains at least one character before a / will not match /image.jpg.
For example:
rewrite .(/[^/]+\.jpg)$ $1 permanent;

Nginx rewrite with and without trailing slash

I'm trying to create a set of rules that match a url with and without a trailing slash
Most of the answers were pointing me to use something similar to this.
location /node/file/ {
rewrite ^/node/file/(.*)/(.*)$ /php/node-file.php?file=$1&name=$2;
rewrite ^/node/file/(.*)/(.*)/?$ /php/node-file.php?file=$1&name=$2; │
}
But this does not match the trailing slash url.
How can I write a rule that matches urls that look like
http://example.com/node/file/abcd/1234/
http://example.com/node/file/abcd/1234

The first rewrite statement includes (.*) as the last capture, which will match any string, including one with a trailing slash.
Use the character class [^/] to match any character except the /:
rewrite ^/node/file/([^/]*)/([^/]*)$ /php/node-file.php?file=$1&name=$2;
rewrite ^/node/file/([^/]*)/([^/]*)/?$ /php/node-file.php?file=$1&name=$2;
Now you will notice that the first rewrite statement is unnecessary, as the second rewrite statement matches URIs both with and without a trailing /.
So all you need is:
rewrite ^/node/file/([^/]*)/([^/]*)/?$ /php/node-file.php?file=$1&name=$2;

Nginx Regular expression to match first segment of a url

I have some urls like these:
domain.com/article/1234-newstitle
domain.com/article/1234-newstitle/
domain.com/article/1234-newstitle/abc
domain.com/article/1234-newstitle/xpto/abc
domain.com/article/1234-newstitle/qwerty/abc/xyz
I want to catch only the /1234-newstitle/ to redirect these urls and ignore everything after the 1º slash (whatever the number of segments) so I can have:
domain.com/news/newstitle-1234/
The best I could get is:
rewrite ^article/(\d+)-(.*)[^\/]* /new/$2-$1/ permanent;
but $2 matches everything after 1234-
How am I able to match only the first segment "1234-newstitle" and ignore the rest?

Looks like you've got a greedy match after the hyphen. Try this:
rewrite ^/article/(\d+)-([^/]+) /new/$2-$1/ permanent;
