Your commands are failing because you are not accounding for the carriage
returns. as was said, this change was intentionally done for the purpose of
making scripts MORE portable:

if you want to keep your grep command, you need to remove CR first:

    $ printf 'alpha\r\nbeta\r\n' > CRLF.txt
    $ tr -d '\r' < CRLF.txt | grep 'a$'
    alpha
    beta
