Linux / UNIX: Display file inode (index number)
Q. How do I display file inode number using command line?
A. An inode is a data structure on a Unix / Linux file system. An inode stores basic information about a regular file, directory, or other file system object. You can use following two commands to display an inode:
[a] ls command : list directory contents
[b] stat command : display file or file system status
ls command
Type ls command with -i ( print the index number of each file ) option:
$ ls -i /etc/passwd
Output:
752010 /etc/passwd
752010 is index number (inode) for /etc/passwd file.
stat command
$ stat /etc/passwd
Output:
File: `/etc/passwd'
Size: 2026 Blocks: 8 IO Block: 4096 regular file
Device: 811h/2065d Inode: 752010 Links: 1
Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2007-08-20 23:19:20.000000000 +0530
