Getting absolute paths with the Unix ls command

The standard Unix command ls lists filenames and directories in the specified directory. The default behaviour is to list just the filenames as including the full pathname would clutter the screen.

But sometimes you want the absolute paths. I need this all the time if I want to create a file containing a list fo filenames. The obvious command to get all the YAML files, for example, is:
$ ls -1 *yml
A.yml
B.yml

In order to get the full pathnames you need to use this:
$ ls -1 -d $PWD/*yml
/home/jones/A.yml
/home/jones/B.yml
