Subject: read builtin return non-zero status reason
To: help-b...@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.
