Inode: is it both unique and 'permanent'?
I try to understand the meaning of an inode. I wonder whether
- an inode is unique (I'm pretty sure it is) and
- whether it remains the same inode regardless of whatever happens to the file, dir or whatever?
I read somewhere that an inode stores info about the file, size... so changing the size might change the inode?
Btw, is there a difference in both features in different platforms? I'm on a mac, but would a linux system be much different?

I have 84 files with the following names splitseqs.1, spliseqs.2 etc.
and I want to change the .number to a unique filename.
E.g.
change splitseqs.1 into splitseqs.7114_1#24
and
change spliseqs.2 into splitseqs.7067_2#4
So all the current file names are unique, so are the new file names.... (1 Reply)

NAME
ffind - Finds the name of the file or directory using a given inode
SYNOPSIS
ffind [-aduvV] [-f fstype] [-i imgtype] [-o imgoffset] [-b dev_sector_size] image inode
DESCRIPTION
ffind finds the names of files or directories that are allocated to inode on disk image image. By default it only will only return the
first name it finds. With some file systems, this will find deleted file names.
ARGUMENTS
image [images]
One (or more if split) disk or partition images whose format is given with '-i'.
inode Integer of inode to find.
The optional arguments are:
-a Find all occurrences of inode.
-d Find deleted entries only.
-f fstype
Identify the file system type of the image. Use '-f list' to list the supported file system types. If not given, autodetection
methods are used.
-u Find undeleted entries only.
-i imgtype
Identify the type of image file, such as raw or split. Use '-i list' to list the supported types. If not given, autodetection
methods are used.
-o imgoffset
The sector offset where the file system starts in the image.
-b dev_sector_size
The size, in bytes, of the underlying device sectors. If not given, the value in the image format is used (if it exists) or
512-bytes is assumed.
-v Verbose output to stderr.
-V Display version.
This program searches all directory entries looking for the given inode. This is useful when an inode has been identified from a disk unit
address using ifind(1).
EXAMPLE
# ffind -a image 212
