usage: stat [-f] [-c FORMAT] FILE...
- display file or file system status
-
- -f display file system status instead of file status
- -c use the specified FORMAT instead of the default;
- output a newline after each use of FORMAT
-
- The valid format sequences for files:
- %a Access rights in octal
- %A Access rights in human readable form
- %b Number of blocks allocated
- %B The size in bytes of each block
- %d Device number in decimal
- %D Device number in hex
- %f Raw mode in hex
- %F File type
- %g Group ID of owner
- %G Group name of owner
- %h Number of hard links
- %i Inode number
- %n File name
- %N Quoted file name with dereference if symbolic link
- %o I/O block size
- %s Total size, in bytes
- %u User ID of owner
- %U User name of owner
- %x Time of last access
- %X Time of last access as seconds since Epoch
- %y Time of last modification
- %Y Time of last modification as seconds since Epoch
- %z Time of last change
- %Z Time of last change as seconds since Epoch
-
- The valid format sequences for file systems:
- %a Available blocks for unpriviledges user
- %b Total number of blocks
- %c Total number of inodes
- %d Number of free inodes
- %f Number of free blocks
- %i File system ID
- %l Maximum length of file names
- %n File name
- %s Fragment size
- %S Optimal transfer block size
- %t File system type
