I'm not certain, from the words here and in the Subject: line, but I
think you are asking for something like:

* request /abc/ returns the content of /tmp/thisfile.txt
* request /abc/anything returns the content of /tmp/thisfile.txt
(for any value of "anything")
* request /abcd does not return the content of /tmp/thisfile.txt
* request /abc either returns the content of /tmp/thisfile.txt, or maybe
returns a redirect to /abc/ (which then gets to item #1 again)

The first three of those can be done (assuming no overriding location)
with

location ~ ^/abc/.* { alias /tmp/thisfile.txt; try_files "" =404; }

where the "=404" is just in case your file does not exist.

The fourth might be done with

location = /abc { return 301 /abc/; }

You may also want to set default_type if what is there already does not
do what you want.

That should probably not happen with "alias". If you show the config,
the request, and the response, maybe it can be explained.

As it happens, I first thought that just

location ~ ^/abc/.* { alias /tmp/thisfile.txt; }

would work, but the ngx_http_index_module handles requests ending in
/ before this config takes hold, so the extra "try_files" is used to
avoid that.

There may well be a better way.

Cheers,
