1 /* stat.c : display file or file system status
11     usage: stat [-tfL] [-c FORMAT] FILE...
15     -c	Output specified FORMAT string instead of default
16     -f	Display filesystem status instead of file status
17     -L	Follow symlinks
18     -t	terse (-c "%n %s %b %f %u %g %D %i %h %t %T %X %Y %Z %o")
19     	      (with -f = -c "%n %i %l %t %s %S %b %f %a %c %d")
24     %D  Device ID (hex)     |%f  All mode bits (hex)|%F  File type
35     %d  Free inodes         |%f  Free blocks        |%i  File system ID
36     %l  Max filename length |%n  File name          |%s  Best transfer size
