I think that osh is valuable precisely because of that, since it's bash compatible. The project also has ysh which is not bash compatible, but fixes a lot of shell brokeness, including the #1 source of shell bugs, the need to quote almost 99% of variables and subshell invocations (and not quote them in the rare case you actually want splatting) https://oils.pub/osh.html https://oils.pub/osh.html https://oils.pub/ysh.html https://oils.pub/ysh.html
