How to see information inside inode data structure
16,573
Solution 1
If you have a ext2/3/4 filesystem you can use debugfs
for a low-level look at an inode. For example, to play without being root:
$ truncate -s 1M myfile
$ mkfs.ext2 -F myfile
$ debugfs -w myfile
debugfs: stat <2>
Inode: 2 Type: directory Mode: 0755 Flags: 0x0
Generation: 0 Version: 0x00000000
User: 0 Group: 0 Size: 1024
File ACL: 0 Directory ACL: 0
Links: 3 Blockcount: 2
Fragment: Address: 0 Number: 0 Size: 0
ctime: 0x5722081d -- Thu Apr 28 14:54:53 2016
atime: 0x5722081d -- Thu Apr 28 14:54:53 2016
mtime: 0x5722081d -- Thu Apr 28 14:54:53 2016
BLOCKS:
(0):24
TOTAL: 1
The command stat
takes a inode number inside <>
.
Solution 2
You can find inode information using stat
command.
# stat myfile.txt
File: myfile.txt
Size: 2023 Blocks: 8 IO Block: 4096 regular file
Device: fd03h/64771d Inode: 15997895 Links: 1

Solution 3
an inode wil store only one file. try
find /xxx -xdev -inum 1234 -print
where
-
/xxx
is mounting point -
-inum 1234
search for an inode number 1234 -
-print
self explainatory
This suppose /xxx is mounted an healthy.

I can do an
ls -li
to see a file's inode number, but how can I list information inside a particular inode by using that inode number.-
Mat almost 8 yearsPlain
ls -l
? What information are you after exactly? -
Ijaz Ahmad almost 8 yearsOk i just tried the stat command on the file name , and most of the information an inode contains is reported by stat command
