rbenv-doctor script fails: `printc:3: bad substitution` about rbenv HOT 2 CLOSED

The behaviour you mentioned can also be reproduced under MacOS Ventura 13.5 with zsh 5.9

I have two workarounds:

1. Save it locally with curl -L https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-doctor > rbenv-doctor, make it executable with chmod +x rbenv-doctor and run it like a normal script
2. Assuming you are calling the script through curl, instead of pipeing it through zsh you could pipe it through bash: curl -fsSL https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-doctor | bash

Both of the above worked in my case.

@apblack: Like @tibix pointed out, rbenv-doctor is a bash script and not compatible with zsh. This is evident in both the script's "shebang" line and by our documentation instructing users to execute the script through the bash interpreter.
