usage: stat [-f] [-c FORMAT] FILE...
Display status of files or filesystems.
-f display filesystem status instead of file status
-c Output specified FORMAT string instead of default
The valid format escape sequences for files:
%a Access bits (octal) |%A Access bits (flags)|%b Blocks allocated
%B Bytes per block |%d Device ID (dec) |%D Device ID (hex)
%f All mode bits (hex) |%F File type |%g Group ID
%G Group name |%h Hard links |%i Inode
%n Filename |%N Long filename |%o I/O block size
%s Size (bytes) |%u User ID |%U User name
%x Access time |%X Access unix time |%y File write time
%Y File write unix time|%z Dir change time |%Z Dir change unix time
The valid format escape sequences for filesystems:
%a Available blocks |%b Total blocks |%c Total inodes
%d Free inodes |%f Free blocks |%i File system ID
%l Max filename length |%n File name |%s Fragment size
%S Best transfer size |%t Filesystem type |%T Filesystem type name
