stat
stat [options] files
Print out the contents of an inode as they appear to the stat system call in a human-readable format. The error messages "Can't stat file" and "Can't lstat file" usually mean the file doesn't exist. "Can't readlink file" generally indicates that something is wrong with a symbolic link.
Options
Display the output as specified by format.
Display information about the filesystem where the file is located, not about the file itself.
Display help information and exit.
Follow links and display information about the files found.
Print the output tersely, in a form suitable for parsing by other programs.
Print version information and exit.

File type.
Owner's group ID.
Owner's group name.

Minor device type in hex.
Owner's user ID.
Owner's username.
Last access time.
Last access time as seconds since the Epoch.
Last modification time (modification of the file contents).
Last modification time as seconds since the Epoch.
Time of last change (modification of the inode).

If both -c format and -f are specified, the following sequences can be used for format:
Free blocks available to nonroot user.
Total data blocks in filesystem.
Total file nodes in filesystem.
Free file nodes in filesystem.
Free blocks in filesystem.
Filesystem ID, in hex.
Maximum filename length.
Filename.
Optimal transfer block size.
Type in hex.
Type in human-readable form.
Examples
Sample output from the command stat /:
stat / File: "/" Size: 4096 Blocks: 8 IO Block: 4096 Directory Device: 303h/771d Inode: 2 Links: 19 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: Thu Jan 2 04:02:40 2003 Modify: Wed Jan 1 23:03:20 2003 Change: Wed Jan 1 23:03:20 2003
Sample output with -f, displaying information about the filesystem:
stat -f / File: "/" ID: 0 0 Namelen: 255 Type: ext2/ext3 Blocks: Total: 2612475 Free: 1869472 Available: 1736735 Size: 4096 Inodes: Total: 1329696 Free: 1150253
