```SHOPT_BASH``` option was present in ```ksh93u+```. You can see it in the code [here](https://github.com/att/ast/blob/2012-08-01-master/src/cmd/ksh93/sh/main.c#L215).

Some of the code under ```SHOPT_BASH``` is operational even without enabling bash emulation mode. For e.g. test for [```local``` keyword]( https://github.com/att/ast/blob/master/src/cmd/ksh93/bltins/typeset.c#L385). ```SHOPT_BASH``` macro has been enabled by default for long...

```SHOPT_BASH``` option is not enabled on RHEL or Fedora. It is not enabled on openSUSE either. It was turned on by default in the last ```beta``` release. Related log from...

I would prefer to keep all the code under `SHOPT_BASH` disabled by default in the next release. @krader1961 We should defer adding features you mentioned in last comment. I am...

Ksh uses sockets instead of real pipes to implement pipes in shell. This has caused issues on multiple occasions. For e.g. ``` $ cat /etc/passwd | head -1 /dev/stdin head:...

`read` builtin in `empty_fifos` function gets blocked because there is a minor difference between time when `read` should timeout and the time `sigalrm` gets invoked. This is related code in...

@krader1961 I suspect you are not hitting this race because you are on a slower system. I am able to reproduce it consistently even with changes from #631.

I have made several observations while debugging this issue. I am going to summarize them here: 1. Size of array that stores trap handlers is calculated based on value of...

@krader1961 The bug that I mentioned in second point of my previous comment is still reproducible, so I think we should reopen this.

@krader1961 As I understand, this issue tracks a regression that was introduced by fa9673c64d5e0dd043d4a2f5c19c43e8189dfd44. I believe if we want to provide `dirs`, `pushd` and `popd` commands, it will be better...
