DESCRIPTION

       fsextinfo is a utility to determine information about an Extended File System (ext) volume

       fsextinfo  is  part  of  the  libfsext package.  libfsext is a library to access the Extended File System

               show information about a specific inode or "all"

       -F path
               show information about a specific file entry path

       -h      shows this help

       -H      shows the file system hierarchy

       -o offset
               specify the volume offset

       -v      verbose output to stderr

       -V      print version
