A+ Exam notes Linux and Windows Commands - A Relative Comparison 'When comparing the command-line interfaces of Linux and Windows, it's important to differentiate between the traditional Windows Command Prompt (cmd.exe) and the more modern Windows PowerShell. Here's a breakdown of major command features and a comparison: Linux Command Line (Bash/Shell): Core Philosophy: Linux command-line environments, primarily using shells like Bash, are deeply integrated into the operating system. They are designed for powerful text processing, system administration, and automation. "Everything is a file" philosophy: This means that almost every system resource is treated as a file, which can be manipulated with command-line tools. Key Features: Powerful Text Processing: Utilities like grep , sed , and awk enable advanced text searching, manipulation, and filtering. Piping ( | ) and redirection ( > , >> , < ) allow for flexible command chain...
