How to check directory size in Linux/Ubuntu via command line
Tags: linux, terminal, beginners, command
Published: 2024-01-25 14:19:26

(Note: It works for MacOS too)

If you need to check the size of a directory on your computer, it is better to use special tools such as **ncdu**, **dust** or **tree**. I prefer ncdu - it does the job!

But, it is more common to use CLI if you work with a remote machine, often without a permission to install additional software into it. Then pre-installed tools come to rescue - **du**. See how I use it below.

```
du -h .
```

This gives us a list of all directories and subdirectories in current directory. That's not what we meant, huh?
Note: The **dot character** can be replaced with a relative or absolute directory path.

```
du -sh .
```
The option `-s` stands for summary result. Now we see the entire folder size. But still, how to see each subfolder individually?

```
du -sh ./*

# or just:
du -sh *
```
Here it is! Now we see the size of each subfolder of 1st level.

```
du -sh .[^.]* *
```
Then you might want to see hidden folder and files too. A bit more complicated with regular expression.

Moreover, usually we would like to see result sorted, the largest elements come first:

```
du -sh * | sort -rh
```
The sort options `-r` is for reverse, and `-h` is for natural/numeric sort order.

These are just the basics, please share your favourite method in the comments.

Navigating the Seas of Undefined with Optional Chaining in JavaScript
Published: 2024-01-25 13:53:42

Optional Chaining is a powerful feature introduced in ECMAScript 2020 that helps JavaScript developers navigate through the perils of potentially undefined or null values in object property access. Let's embark on a journey to explore the beauty and utility of Optional Chaining.


**The Old Seas: Dealing with Undefined**
In the old days of JavaScript, accessing nested properties in an object could feel like navigating treacherous seas, especially when encountering undefined or null values.
```js
// The Old Way
const city = user.address && user.address.location && user.address.location.city;
```

**Introducing Optional Chaining**
Optional Chaining provides a concise and elegant solution to the problem of checking nested properties. It allows you to safely access nested properties without the need for explicit checks.
```js
// The New Way with Optional Chaining
const city = user?.address?.location?.city;
```

**Unveiling the Syntax**
The syntax of Optional Chaining is straightforward. Simply append a ?. between each nested property you want to access. If any of the properties in the chain is undefined or null, the entire expression evaluates to undefined. A Real-world Example:
```js
// Data from API
const userData = {
  id: 1,
  username: 'devmatsu',
  shippingInfo: {
    address: {
      city: 'São Paulo',
      country: 'Brazil'
    }
  }
};

// Using Optional Chaining to access the city
const userCity = userData?.shippingInfo?.address?.city;

console.log(userCity); // 'Brazil'
```

Optional Chaining brings clarity and safety to your code, allowing you to sail smoothly through the seas of undefined values. Embrace this modern JavaScript feature to enhance the readability and maintainability of your code.

What is Software testing? What we need to know about SW testing? What is relevance of software testing?

Software testing is the method to verify the SW developed with the specific requirement is working as per the requirement. 
SW developed should be defect free after the testing. Static testing and Dynamic testing are the types of testing.

Static testing mainly done in developer side to make sure that SW code is working fine and the requirement mistakes also identified during Static testing.
70% of the defects can be identified during static testing time only.


Dynamic testing will be done by testing team, to make sure that Requirement implemented is working fine. 30% of testing will be completed. 
Software testing is done at the run time to analyze the dynamic behavior of the code.

Software testing Life cycle will be as below :
 
1. Requirement Analysis -> Test Planning  -> TC Development -> Test Environment setup -> TC Execution -> Closure.

Requirement Analysis: Where the requirement of SW will be analyzed at this phase.

Test planning: Planning phase involves recourse estimation and testing efforts involved

TC case development: Test case will be developed for this project requirement, 
different techniques like boundary value analysis, Requirement traceability matrix, equivalent partition, etc. will be used for writing the test cases.

Test Environment : Test environment decides the conditions on which software need to be tested similar like customer environment to verify all the cases including Adhoc test.

TC Execution: After the TC development and test environment setup,  test execution will be done for developed TCs. Defects will be reported at this stage if the requirement is 
not matched. 


Test  closure:  Once the testing activities are completed, Same will be documented along with defect reported list for tracking.
