To: help-bash@gnu.org

The bash read builtin documentation said that when read reached EOF, it's return non-zero status. So in:

read -d '' l <<- EOF

    test

EOF

Did read return non-zero status because of it reached EOF or it failed to read the whole input because it could not find the delimiter?

IMHO, the second reason is correct.

The full story is here: http://unix.stackexchange.com/q/265149/38906. I and the other one have conflict about this.

Correct me if I'm wrong.

Thanks.
