/Users/yuma/.rbenv/bin
./vendor/bin
/Users/yinaura/google-cloud-sdk/bin
/usr/local/opt/openssl/bin
/Users/yuma/.pyenv/shims
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

small letter $path is array

echo $path
/Users/yuma/.rbenv/shims /Users/yuma/.rbenv/bin ./vendor/bin /Users/yinaura/google-cloud-sdk/bin /usr/local/opt/openssl/bin /Users/yuma/.pyenv/shims /usr/local/bin /usr/bin /bin /usr/sbin /sbin

for loop example

for p in "${path[@]}"; do echo "$p"; done

/Users/yuma/.rbenv/shims
/Users/yuma/.rbenv/bin
./vendor/bin
/Users/yinaura/google-cloud-sdk/bin
/usr/local/opt/openssl/bin
/Users/yuma/.pyenv/shims
/usr/local/bin
/usr/bin
