Exit code 0 even if sudo password is not provided

[HarimbolaSantatra]

Issue

When installing using install.sh, if I don't provide password when moving the executable to the installation directory,

...
    if command -v sudo >/dev/null 2>&1; then
        sudo mv /tmp/pocketenv $INSTALL_DIR
...

, the script will continue, will print

Installation completed! 🎉
To get started, run:
pocketenv init

and will exit with status code 0, even if the executable will still be at /tmp/pocketenv and not at /usr/local/bin.
