功能说明:获取文件的属性,例如大小,最后的修改时间等Linux/1672.html' target='_blank'>inode内容, stat以文字的格式来显示inode的内容。

语法:stat [文件或目录]

参数:
# stat --help
Usage: stat [OPTION] FILE...
Display file or file system status.

  -L, --dereference     follow links
  -Z, --context         print the security context information if available
  -f, --file-system     display file system status instead of file status
  -c  --format=FORMAT   use the specified FORMAT instead of the default;
                          output a newline after each use of FORMAT
      --printf=FORMAT   like --format, but interpret backslash escapes,
                          and do not output a mandatory trailing newline.
                          If you want a newline, include \n in FORMAT.
  -t, --terse           print the information in terse form
      --help     display this help and exit
      --version  output version information and exit

The valid format sequences for files (without --file-system):

  %a   Access rights in octal
  %A   Access rights in human readable form
  %b   Number of blocks allocated (see %B)
  %B   The size in bytes of each block reported by %b
  %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

  %t   Major device type in hex
  %T   Minor device type in hex
  %u   User ID of owner
  %U   User name of owner
  %x   Time of last access

  %y   Time of last modification

  %n   File name
  %s   Block size (for faster transfers)
  %S   Fundamental block size (for block counts)
  %t   Type in hex
  %T   Type in human readable form
