To be clear: `.' is a shell builtin, with its own semantics and exit status: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_18 Like any other builtin, it's a simple command when executed as one. And like any other builtin, if it returns a non-zero exit status when errexit is enabled, the shell will exit.
