This is the equivalent of:
admin:file list activelog /core
<dir> analyze
core.13869.11.cef.1290616611
dir count = 1, file count = 1

The latter has the advantage that you know the absolute path, which you need when you want to retrieve the file.
The file can be retrieved via the RTMT as well as via the CLI. All you need is an SFTP server on which you have write access, in this case I used a CentOS server running openssh. Here it goes:
admin:file get activelog /core/core.13869.11.cef.1290616611
Please wait while the system is gathering files info ...done.
