$BASH hardcoded to `/bin/bash` when it should be `/opt/homebrew/bin/bash`

Regression

No, this bug or issue has existed throughout my experience using Warp

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

Yes, this I confirmed this only happens in Warp, not other terminals.

command -v bash or which bash will tell you which binary is being found first in your $PATH. It could be that your path is out of order, and it's finding /bin/bash first.

[luckman212]

Not sure how this is possible then- which and command -v both point to the Homebrew version, which is 5.x, and the PATH lists /opt/homebrew/* before /bin...

@luckman212 This happens for iTerm and Mac terminal as well?

Is the variable that you meant to use: $SHELL or $0

[luckman212]

No, I am not trying to use $0 or $SHELL

Here is iTerm:

and Terminal:

and again, Warp:

This is now Warp v0.2023.09.06.18.09.stable_00

@luckman212 thanks for this!

I have the same issue, too. This prevents me from using newer features of bash like mapfile. Terminal and iTerm2 don't have this issue.

In Warp:

$ type mapfile
bash: type: mapfile: not found
$ echo $BASH
/bin/bash
$ declare -p BASH_VERSION
declare -- BASH_VERSION="3.2.57(1)-release"
$ echo $BASH_VERSION
3.2.57(1)-release

In iTerm2 and Terminal:

$ type mapfile
mapfile is a shell builtin
$ echo $BASH
/opt/homebrew/bin/bash
$ declare -p BASH_VERSION
declare -- BASH_VERSION="5.2.15(1)-release"
$ echo $BASH_VERSION
5.2.15(1)-release

Can we have this bug fixed? It's very annoying.
