I would like to grep or cat only files that begin with a specific number and are in a range until a specific number, e.g.:

abc_server.2022-04-09-34.log 

until

abc_server.2022-04-09-50.log

How can I do this?

I tried using cat: cat abc_server.2022-04-09-3* but obviously it does not give me the expected results.

You can use Brace Expansion for numeric ranges. Here's an example:

$ echo file_{09..12}.txt
file_09.txt file_10.txt file_11.txt file_12.txt

Note that this is not wildcard matching. The expansion happens irrespective of whether files with those names exist.

So, if you use cat file_{09..12}.txt, the four filenames shown above will be passed as arguments to the cat command.
