Chaning MacVim's default shell?

Question

I currently have my default shell set to zsh in terminal. However, upon execution !echo $SHELL in MacVim, it returns /bin/bash, which is obviously the shell that I don't want. How can I set zsh as my default in MacVim?

Note: I've attempted to :set shell=/bin/zsh with no luck.

Answer 1

Although !echo $SHELL may be wrong, :set shell=/bin/zsh does seem to work.

Like you, I also get /bin/bash for !echo $SHELL. But if I try to run a non-existent command:

:!blah
zsh:1: command not found: blah

shell returned 127

So it looks like the setting works, and commands will be executed in the right shell.
