Write modern, simple, informative shell scripts with these shell variables. — Developers typically use Bash to write shell scripts by invoking other programs as commands and adding inbuilt Bash language features. Also, every Unix or Unix-like system user uses Bash to communicate with the operating system via GUI terminal programs. A shell script written in Bash contains several syntactical elements. Bash…

These facts made web development one of my favorite fields — I started programming when I was thirteen years old with Visual Studio 6.0 IDE. A few months later, I printed hello world with Java. At that time, I didn’t have an internet connection, so I used physical books, tutorial CDs, and inbuilt documentation to learn programming syntax and APIs. I…

Process strings productively in your automation scripts with these syntaxes — Bash became every Unix-like or Unix-based operating system’s default automation language. Every system administrator, DevOps engineer, and programmer typically uses Bash to write shell scripts with repetitive command sequences. Bash scripts typically contain commands that run other program binaries. In most scenarios, we may have to process data and create…

These lessons motivated me to live with programming forever! — Programming isn’t just coding with a favorite programming language — it refers to designing, developing, testing, and maintaining software systems. Programming usually involves the entire software development life cycle (SDLC) that every software team follows. But, every developer steps into the programming field by coding with their first programming language…

Use these coding techniques to write fast and readable shell scripts — Bash undoubtedly became every modern Unix-like or Unix-based operating system’s native, inbuilt automation solution. Programmers use Bash to automate their repetitive command-line tasks by creating shell scripts. The primary goal of Bash is to offer a minimal syntax to execute other programs and work with their exit codes and output…

Some languages just come and go, but these will remain forever — There are thousands of programming languages worldwide, but we typically know and use a few languages that most developers use to build software systems. Programming languages usually become popular because of various reasons, such as language features, cross-platform support, fully-featured standard API, rich libraries ecosystem, developer support, etc. Meanwhile, some…

Comparing Bash and Python options for modern automation requirements — A computer is a digital device that can only understand specific binary instructions. Without an operating system, we can only use some inbuilt firmware, such as BIOS utilities in computers. Operating systems make computers usable for people by offering a way to execute pre-developed programs (i.e., word processors, web browsers…

Save your time by using these command combinations in your terminal and scripts — Most developers who use Unix-based or Unix-like operating systems like to instruct the computer via the terminal. They typically use standard (POSIX) Unix/Linux commands and other system commands to handle file operations, system configurations, and process control. Programmers strive to save time by following various command-line tips, such as using…

These historical codebases built the foundation of today’s computer technology — Like any other field, computer technology has an impressive, progressive history. Today, we use high-end computers, high-quality modern GUIs, human-friendly programming languages, and real-time futuristic web apps, thanks to the hard work done by past programmers. Learning history makes us happy— it’s so interesting to see the progressive growth in…
