So I just rewrote a large portion of a codebase on being able to
use `printf -v`, but it looks like this support was added
after ZSH 5.1, which I intend to support. (Ubuntu 16.04 still has
it.) So I guess the question is up again, how should I capture the `printf`
output without the `-v` option, no subshells, and no file
I/O? Is there a different method for ZSH v5.1? I would like to do `printf '%.2f' "3.4" | read var` but it appears that the command before the pipe causes a subshell to be opened. Or potentially, is there some way I can make a wrapper that will
use `printf -v` when available, but falls back to another
method? On 09/03/2018 02:43 PM, Joey Pabalinas
