I too often find it inconvenient that bash won't ignore CRs. The best fix
I've found is to put a file "igncr.sh" into /etc/profile.d. This file
contains:
(shopt -s igncr) 2>/dev/null && shopt -s igncr # comment is needed if crlf
export SHELLOPTS
Once this file is in place, shell scripts will ignore CR characters. I've
used this solution ever since bash was changed to complain about CR by
default, and it has worked well for me.
I was going to make some comment about ANSI C/C++ recognising that line
endings can legitimately be something other than just LF, and text files on
the system defaulting to CR/LF line endings, and bash shell scripts being text
files, and cygwin providing useful tools to interoperate with the native OS.
But then I thought it better to just offer the solution above. :)
