Bash Version: 4.4 Patch Level: 0 Release Status: release Description: Handling of here-documents in command substitution seems to be inconsistent. $ cat test.sh export foo=$(cat <<EOF echo bar EOF) echo baz $ bash test.sh test.sh: line 6: warning: here-document at line 4 delimited by end-of-file (wanted `EOF') baz I see only two possibilities: 1) here-document is ended with the "EOF)" line, which also closes command substitution; then, bash should't have produced the warning; 2) here-document is not ended with the "EOF)" line and, indeed, spans to the end of file; then, bash shouldn't have executed the line which reads "echo baz". But it does both. In bash-3.2, it used to work without a warning: $ bash-3.2 test.sh baz In bash-4.2, the warning is already there: $ ./bash-4.2 test.sh test.sh: line 6: warning: here-document at line 4 delimited by end-of-file (wanted `EOF') baz
