Bash Version: 3.1
Patch Level: 17
Release Status: release
Description:
As worded, the documentation does not make it clear what the
behaviour of some scripts is under "set -e". For reference,
this was discussed earlier today on #bash on Freenode.
To be precise, there is an ambiguity in what means "being part
of" a particular construct. It is easy to interpret this as
"directly part of", whereas all shells at hand are consistent
in this behaviour:
$ bash -ec '(echo 1; false; echo 2); echo 4'
1
4
$ bash -ec '(echo 1; false; echo 2) || echo 3; echo 4'
1
2
4
$ bash -ec 'foo() { echo 1; false; echo 2; }; foo'
1
$ bash -ec 'foo() { echo 1; false; echo 2; }; foo || echo bar'
1
2
