Or July??

ls -al | awk '/Jul/{ print "rm",$9 }' > /tmp/somefile

Next (and this step is very important), check over /tmp/somefile in your
editor and make sure it is right. When you are sure, then do:

sh /tmp/somefile

And if you have spaces in your filenames quote those names.
(Or let the awk program print some quotes around $9.)

Good point, but note that if the filenames have spaces in them, then $9
isn't going to pick it up anyway. So, you'll have to re-analyze that
part of the problem as well.

Indeed, right you are.

Having now a closer look at the OP's task I wonder why there's the -a
option; it would be "tricky" to remove . and .. with a rm command.

And the pattern /Jul/ should be restricted to the respective date
field as to not accidentally remove a file called Julian.txt or any
file that has a user or group field containing "Jul".

And some systems have a different number of fields in the ls command,
depending on whether the file is older than 6 months or not.

....there's still some work to make that command more robust.
