Auto-script

Always be curious, always read the source material, and always try it yourself.

"learn the basics/roots first" principle applies to pretty much everything in life. From learning a new programming language to starting a new sport. It requires a lot of practice, but once you master it, the only thing left to do is to get creative with it. And that's where the real fun begins.

Initiative for creating easy auto scripts Snippets are reusable with little or no changes . If you are new to programming or simply interested in learning different scripts, here are some resources you can use.

Test driven approach

The best way to do code testing is by using Test-Driven Development (TDD).

This is how it works:

Write a test. – The test will flesh out some functionality in your app.

run the test – The test should fail, since there's no code to make it pass.

Write the code – To make the test pass

Run the test – If it passes, you are confident that the code you've written meets the test requirements

Refactor code – Remove duplication, prune large objects and make the code more readable. Re-run the tests every time you refactor the code

Repeat – That's it!

Types of Application development

• Standalone business application: This is your typical application, and is like applications like Word, Excel, Outlook and more. Anything that can be used by someone to make their work more efficient would fall into this category.
• Client-Server Application: This is an application that runs on the computer but accesses information from a remote server.
• Collaborative Application: This is an application that is designed to help people involved in a common task. This is a way for people to work together at once, using the same application on each of their computers.
• Utilities and Plug-Ins: Anything that can help a computer or browser run more efficiently would fall into this category.
• System Apps and Services: Anything that allows the computer to run various other applications would fall into this category.
• Multimedia Applications: This is an application that plays podcasts, movies, video, music and more. iTunes is a good example of this.
• Network Applications: Anything that runs over a network falls into this category.

ssh with two linux computer

• connect with lan cable between two computer
• install, enable, start ssh service
• also compulsary to add password in linux machine
• ping ssh with ping ipaddress
• ssh remote linux with ssh ipaddress
• scp -r /file path/to/copy user@ipaddress:/path/to/paste
• ls -lh //list path with human readable file size

Git

Use aliases. Though there aren't any native Git one-liners, you can define your own as

git config --global alias.clone-branches '! git branch -a | sed -n "/\/HEAD /d; /\/master$/d; /remotes/p;" | xargs -L1 git checkout -t'

and then use it as

git clone-branches
