Linux Cheatsheet

Process management in Linux involves monitoring, controlling, and manipulating running processes. These commands help you identify resource usage, terminate problematic processes, and adjust process priorities to optimize system performance.

Linux provides powerful tools for searching files, locating patterns within them, and processing text streams. These utilities can be combined through pipes to create complex data processing workflows.

Text processing utilities are the Swiss Army knives of Linux command line, allowing you to extract, transform, and analyze text data with surgical precision. These tools follow the Unix philosophy of doing one thing well and can be combined through pipes to create powerful data processing pipelines.

System monitoring tools provide insights into system performance, resource usage, and bottlenecks. They help identify issues related to memory, CPU, disk I/O, and network activity, making them essential for troubleshooting and performance optimization.

Network tools in Linux provide powerful capabilities for transferring data, monitoring network connections, analyzing traffic, and diagnosing network issues. These utilities are essential for system administrators and developers working with networked applications.

Linux disk management commands help monitor storage usage, manage partitions, and mount filesystems. These utilities are essential for system administrators to maintain disk health, optimize storage allocation, and troubleshoot space issues.

User management in Linux involves creating, modifying, and deleting user accounts, managing passwords, and controlling user privileges. These commands help system administrators maintain proper access control and security.

Shell scripting allows automation of tasks by combining commands, variables, control structures, and functions into executable files. Bash (Bourne-Again SHell) is the most common shell on Linux systems, providing powerful scripting capabilities.

SSH (Secure Shell) provides encrypted communication between systems. It enables secure remote access to servers, file transfers, and tunneling of other network protocols. This section covers essential SSH tools and techniques for effective remote system management.

Job control allows you to manage multiple processes within a shell session. You can suspend running processes, move them between foreground and background, and chain commands together with logical operators.

File compression tools in Linux reduce file sizes for storage efficiency and faster transfers. These utilities offer various compression algorithms with different trade-offs between compression ratio, speed, and compatibility across platforms.

System services are background processes that start when the system boots and continue running to provide functionality. Modern Linux distributions use systemd, while older ones use SysV init scripts. Both systems allow managing services, viewing logs, and scheduling tasks.
