Inode and its corresponding filename
Posted 07-21-2009 at 09:58 AM by Mr. ameya sathe
We refer to a file by its name. Computer refer to the file by its inode numbers. For every filesystem; there is an inode table. This table consists of Inode numbers & its correspondingmetadata. On the contrary; the mapping of filenames to inode numbers is stored in the directory containing the file.
To display the inode number of a file; say hindu one must issue the command
To display the total number of inode numbers in the filesystem ; you must issue the command
The output will show free inodes as well inodes.
To deduce a filename from any inode numbers present in your operating system; issue the command
where; 1234 is the inode number.
Please note; inode tables are only unique to the filesystem & not to the complete operating system. Hence; if you see more than one entry in the output of above command; then it means that
To display the inode number of a file; say hindu one must issue the command
Code:
ls -i hindu
Code:
dumpe2fs /dev/vol0/root
To deduce a filename from any inode numbers present in your operating system; issue the command
Code:
find / -inum 1234
Please note; inode tables are only unique to the filesystem & not to the complete operating system. Hence; if you see more than one entry in the output of above command; then it means that
- Hard Links present for the given inode number.
- The files are present on different filesystems.
