An empty file has a minimum disk size that depends on the disk block size, which can also be referred to as cluster size or IO block size, that depends in turn on the filesystem. This IO block size can be discovered through different utilities in the operating system, such as stat in Unix systems. [2] [3] Typically 4096 bytes.

In computer science, a sparse file is a type of computer file that attempts to use file system space more efficiently when the file itself is partially empty. This is achieved by writing brief information ( metadata ) representing the empty blocks to the data storage media instead of the actual "empty" space which makes up the block, thus ...

For example, the Unix Bash shell command mv *.txt textfiles/ moves all files with names ending in .txt from the current directory to the directory textfiles. Here, * is a wildcard and *.txt is a glob pattern. The wildcard * stands for "any string of any length including empty, but excluding the path separator characters (/ in unix and \ in ...
The total size of the file system in 512-byte units. The exact meaning of this figure is implementation-defined, but should include <space used>, <space free>, plus any space reserved by the system not normally available to a user. <space used> The total amount of space allocated to existing files in the file system, in 512-byte units. <space free>
Let’s make this clear: some bloating can be perfectly normal and not a cause for concern. Whether you’ve eaten a big meal, tried a new food or vigorously exercised, bloating happens.
The command was originally implemented in the first version of Unix as a method to initialize either a DECtape (using the "t" argument) or an RK03 disk pack (using the "r" argument). [1] The initialization process would write formatting data to the device so that it contained an empty file system.
