In Debian bug #716789, you wrote: > [cat <<EOF | sh || echo "`echo hi` die" ... fails]
The cause is likely that the command substitution incorrectly uses the outer here-document state. For example, dash treats these four lines cat <<EOF `true hi EOF ` as a complete command that prints hi. This is incorrect: a here-document shall only be recognized after the next NEWLINE token, and the command substitution is a WORD token. So the here-document should only be read after the fourth line, and hi and EOF should be executed as commands. This problem also occurs if new-style command substitution is used. In the example in the original bug report, the old-style command substitution not containing any newline generates an end-of-file condition on the inner string. Dash then assumes that the here-document is not coming, again corrupting the outer here-document state from the inner parse. This bug was fixed in FreeBSD sh in SVN r208655. I expect it will not be completely trivial to port it over, though. -- Jilles Tjoelker -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
