So we aren't talking past each other, how do you delineate between cargo and a package manager? Does anaconda, pip (pypi) or homebrew also qualify? Your scripts could have a prolog that installs rustup and calls cargo. There is also https://github.com/ryankurte/cargo-binstall https://github.com/ryankurte/cargo-binstall Even after 20 years of bashing, my bash skills still suck. So many corner cases! But if you include this, and call install_utils at the head of your scripts. It should install the tools on demand. #!/bin/bash RUST_PACKAGE_LIST='rg xsv tuc broot du-dust dutree' RUST_UTIL_LIST='rg xsv tuc broot dust dutree' function is_cargo { cargo > /dev/null } function is_utils { eval "which $RUST_UTIL_LIST" > /dev/null } function install_utils { if ! is_utils ; then if ! is_cargo; then curl https://sh.rustup.rs -sSf | sh -s -- -y fi eval "cargo install --locked $RUST_PACKAGE_LIST" > /dev/null fi } I don't recommend using this, it is just illustrative.
