| Thank you for pointing out this. After reading your comment, I was
| interested in the behavior of the Bourne shell, so I have tried with
| the Heirloom Bourne shell (which is a port of the SVR4 Bourne shell
| according to its page) in AUR. Actually, the Heirloom Bourne shell
| turns out to follow the interpretation (A) [ although it might be
| possible that the behavior is changed by the port ].
Probably not, bosh is derived from that shell (more or less) and it is
also A
bosh $ $SHELL /tmp/TTT
In trap argument: last command preceding the trap action
In direct function call: last command in the trap action
In indirect function call: last command in the trap action
bosh $ $SHELL -c 'echo ${.sh.version}'
version bosh 2020/04/10 a+ (amd64-unknown-netbsd8.99.30)
(it is really version 2020/04/18 without the version string being updated).
So are the FreeBSD and NetBSD shells (which is not surprising, as like
dash, they're descendants of ash).
You can also add zsh to A:
zsh $ $SHELL /tmp/TTT
In trap argument: last command preceding the trap action
In direct function call: last command in the trap action
In indirect function call: last command in the trap action
zsh $ echo $SHELL
/usr/pkg/bin/zsh
zsh $ $SHELL -c 'echo ${ZSH_VERSION}'
5.6.2
(/tmp/TTT is your script - but with a newline removed. It might have just
been an e-mail artifact, and was in the middle of one of the messages).
| Thank you for suggesting another possibility. Let me call the above
| one the interpretation (D).
| But there was actually no implementation that follows (D)
I am not all that surprised, it would be a rather bizarre interpretation.
