Examples
Extract the inode and file name for a single file:
inode_name /path/to/file
Extract information for all files in a directory:
inode_name -l /path/to/directory
Extract the inode and file name formatted as a comma-separated list:
inode_name -F '%i,%f' /path/to/file
Common Issues
- Permission denied: Ensure you have sufficient permissions to access the specified path.
Integration
inode_name can be combined with other commands for advanced tasks, such as:
- Find files with specific inodes:
find . -inum `inode_name /path/to/file`
- Create a list of inodes for all files in a directory:
inode_name -F '%i' /path/to/directory | xargs -I{} find . -inum {}
