Once you verify that you have a batch of Flash cookies, find will find and delete them all in one command by using the powerful -exec option, like this:

$ find -iname '*.sol' -exec rm "{}" \;

This means "find all files with the extension .sol and delete them." rm is remove, or delete. "{}" means "replace me with the name of the current file being processed", and the semi-colon means "stop, there are no more commands to execute." The semi-colon must be escaped with the backslash because it has a special meaning to the Bash shell, and we don't want Bash mucking with it.

find is very fast and this will nuke all Flash cookies in an eyeblink. If you're nervous, you can use -ok instead of -exec and you'll be asked to verify each deletion:

$ find -iname '*.sol' -ok rm "{}" \;
$ < rm ... ./s_br.sol > ?

Type y for yes or n for no.
