size

The "size" command line tool is a built-in utility in most operating systems, including Unix, Linux, and macOS. Its main purpose is to display the size of files and directories in bytes. When invoked with the appropriate arguments, it provides a detailed summary of the disk space occupied by each file and directory within a given directory. The tool can be used to analyze disk usage and identify large files or directories that may be consuming excessive storage. It includes options to display the sizes in more user-friendly units like kilobytes, megabytes, and gigabytes. Moreover, the output of the "size" command can be customized to list files and directories based on certain criteria, such as only showing those larger than a specified threshold. Overall, the "size" command is a handy tool for managing disk space and gaining insights into the distribution of file sizes on a system.
