| 3 | # It may be argued that | |
| 4 | # x=$(cat <<EOF | |
| 5 | # foo | |
| 6 | # EOF) | |
| 7 | # is a valid complete command that sets x to foo, because | |
| 8 | # cat <<EOF | |
| 9 | # foo | |
| 10 | # EOF | |
| 11 | # is a valid script even without the final newline. | |
| 12 | # However, if the here-document is not within a new-style command substitution | |
| 13 | # or there are other constructs nested inside the command substitution that | |
| 14 | # need terminators, the delimiter at the start of a line followed by a close | |
| 15 | # parenthesis is clearly a literal part of the here-document. | |

| 17 | # This file contains tests that also work with simplistic $(...) parsers. | |
