If a file has a link count greater than 1 is there a simpler way to find out what other file names are hard-linked to it by Steve Bonneville Red Hat Certified Engineer The obvious answer is that you can t by just looking at the inode the inode only contains a link count not a list of the file names that are hard-linked to the inode. So you need to walk through the filesystem looking for files that have the same inode number as the file of interest. The not so obvious solution is that the find command can do this searching for you once you ve determined the inode number for the file with ls -i. For example find home -mount -inum 78442 works nicely to find all file names using inode 78442 on the filesystem mounted on home. The -mount option is necessary to avoid accidentally searching other filesystems mounted on subdirectories of the home filesystem since inode numbers are only unique within a given filesystem. It is also very important to start the find at the mount point for the filesystem being searched or some files might be missed by find. Copyright 2007 Global Knowledge .
