fsize

fsize is a command-line utility found on Unix-like operating systems, including Linux and macOS. Its primary function is to display the size of a file in a human-readable format. This means that instead of showing the size in bytes, which can be difficult to interpret for large files, fsize converts the size into units like kilobytes (K), megabytes (M), gigabytes (G), and so on.

The typical usage of fsize involves providing the name of the file as an argument to the command. For example, typing fsize mydocument.txt in the terminal would output the size of mydocument.txt along with its name. Some implementations of fsize may offer various options to customize the output, such as specifying the unit of measurement or controlling the precision of the displayed size. However, the core functionality remains consistent: to make file sizes easily understandable at a glance. This is particularly useful for system administrators and users managing large storage spaces, as it quickly allows for an assessment of disk usage. While a similar functionality is often provided by other commands like `ls -lh`, fsize offers a dedicated and streamlined approach to this task.
