فرض کن پایتون رو نصب کردی و توی یه پوشه `/opt/custompython/bin` قرار گرفته.

اگه بگی بله برای به‌روزرسانی متغیر محیطی `PATH`، نصاب `/opt/custompython/bin` رو به متغیر محیطی `PATH` اضافه می‌کنه.

ممکنه اینجوری بشه:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

//// tab | Linux, macOS

Let's say you install Python and it ends up in a directory `/opt/custompython/bin`.

If you say yes to update the `PATH` environment variable, then the installer will add `/opt/custompython/bin` to the `PATH` environment variable.

It could look like this:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

  echo "Setting READ_ONLY Gradle cache via env.GRADLE_RO_DEP_CACHE to use /opt/gradle-cache"

ধরা যাক আপনি পাইথন ইনস্টল করলেন এবং এটি `/opt/custompython/bin` ডিরেক্টরিতে ইনস্টল হচ্ছে।

যদি আপনি "Yes" সিলেক্ট করে `PATH` এনভায়রনমেন্ট ভেরিয়েবল আপডেট করতে চান, তাহলে ইনস্টলার `/opt/custompython/bin` কে `PATH` এনভায়রনমেন্ট ভেরিয়েবল এ এড করে দিবে।

এটা দেখতে এমনটা হতে পারেঃ

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
