But you can use a single stat command to list the property for all your
files. Using the format options for the stat call you can tailor the output
of the command to suit your needs of parsing. For example, if all you want
is group information then you can do something along the lines of:

  stat --format="%n|%U|%G" <list of files>

for example, look at this usage scenario:

  stat --format="%n|%U|%G" base.csv examples.desktop

the output is:


which is a nice parsable format using cr and pipes. First is the file name,
then the owner name, then the group name.

I think that a single stat call querying multiple files is easier than ls -l
or parsing the detailed files and then checking the /etc/ stuff.
