+ 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 File system type
