Linux Find And Report On File Fragmentation

To find and report on file fragmentation in Linux, you can use the "filefrag" command.

The "filefrag" command displays information about the fragmentation of a file, including the number of fragments, the size of each fragment, and the offset of each fragment.

To use the "filefrag" command, you can simply specify the name of the file you want to check. For example:

filefrag /path/to/file

This will display information about the fragmentation of the file.

For example, the output might look like this:

Filesystem type is: ef53
File size of /path/to/file is 99534336 (23936 blocks of 4096 bytes)
