Knowing how to check the file size in Unix is a fundamental task for anyone working with files in this operating system. The file size, typically measured in bytes, kilobytes, or megabytes, indicates the amount of storage space occupied by the file on the disk. Determining the file size is essential for various reasons, such…
Checking whether a file exists in Unix is a fundamental task that allows users and programs to determine the presence of a specific file within the file system. This capability plays a critical role in various operations, such as data processing, system administration, and software development. The ability to verify the existence of a file…
Determining the size of a directory in Unix is a crucial task for managing disk space and organizing files. The command “du” (short for “disk usage”) provides a detailed report of the space occupied by files and directories within a specified path. Using “du” is straightforward: simply type “du” followed by the path to the…
Monitoring CPU usage is crucial for optimizing system performance and ensuring smooth operation. In Unix-based systems, there are several commands that provide detailed information about CPU utilization. The ‘top’ command is a widely used tool that displays real-time information about the system’s overall CPU usage, as well as the processes that are consuming the most…
Determining the operating system (OS) of a Unix-based system is a fundamental task for system administrators and users alike. Unix is a family of multitasking, multiuser computer operating systems that derive from the original Unix developed at AT&T’s Bell Labs in the 1970s. Today, Unix systems are widely used in servers, workstations, and embedded systems,…
