The original didn’t have the where clause.

Bash sucks. At best, only use it to pipe commands into each other in the terminal (Or change your shell to something else). For scripting, use Python or something.

Btw, Powershell runs on Linux if you want that

You can globally share compile artifacts by setting a global target directory in the global Cargo config.

In $HOME/.cargo/config.toml:

[build]
target-dir = "/path/to/dir"

The only problems I had when I did it where some cargo plugins and some dependencies with build.rs files that expected the target folder in it’s usual location.
