[Help-bash] native support for CRLF in heredoc

[Peng Yu]

Hi,

I use `sed` to support CRLF in heredoc.

sed 's/$/\r/g' <<EOF | nc -v httpbin.org 80
GET /get HTTP/1.1
Host:httpbin.org

EOF

Ideally, I would like something simpler (of course the following does
not work as expected).

nc -v httpbin.org 80
GET /get HTTP/1.1
Host:httpbin.org

EOF

Does anybody know anything more native to bash that support CRLF in
heredoc? Thanks.

What's wrong with the 'sed' version? I think that's the simplest you'll get.
