Post-install instructions have a line break in the recommended help command

[orta]

What version of Bun is running?

❯ bun --revision 1.2.5+013fdddc6

What platform is your computer?

Darwin 24.3.0 arm64 arm

What steps can reproduce the bug?

I just ran the installer command on a pretty blank macOS install:

❯ curl -fsSL https://bun.sh/install | bash

######################################################################## 100.0%
bun was installed successfully to ~/.bun/bin/bun 

Added "~/.bun/bin" to $PATH in "~/.zshrc" 

To get started, run: 

  exec /bin/zsh 
  bun --help 

What is the expected behavior?

❯ curl -fsSL https://bun.sh/install | bash

######################################################################## 100.0%
bun was installed successfully to ~/.bun/bin/bun 

Added "~/.bun/bin" to $PATH in "~/.zshrc" 

To get started, run: 

  exec /bin/zsh bun --help 

What do you see instead?

Additional information

Not a biggie, but it does make the command not copy-pasteable

This is set here:

bun/src/cli/install.sh

Line 244 in 21a42a0

refresh_command="exec $SHELL"

I think this formatting is intentional. exec zsh will replace your current shell instance with a new one, which is needed to load the new configuration with Bun in your $PATH. Then you'll be able to run bun --help as a separate command in the new shell. If you run exec /bin/zsh bun --help, your current shell will be replaced by one that just runs bun --help and exits, which means your terminal will close as soon as Bun has printed its help message.

That said, I'm not completely sure why we can't use something like source ~/.zshrc to reload the new configuration in your existing shell, like we do for other shells, instead of starting a new shell with the new configuration. Maybe there's some zsh particularity I'm not familiar with.
