Or if we cannot restrict from inode number getting changed , is there any way to identify the file uniquely as inode number does.
I need a way to differentiate between a.txt that is modified and a.txt that was created after renaming the earlier a..txt to a.txt.1
Kindly reply
Thanks in Advance.

If there are multiple links to a file,
vi file should not change the i-node number. If there is only one link to a file and you make any changes to the file using
vi, it is more efficient to rename the temp file to the final resting place rather than copy the temp file onto the original file and then remove the temp file.
Why do you care if the i-node number changes? Why isn't the file's name (
a.txt) sufficient for identifying the file?
(Note that
ls -i and
ls -li will also give you the i-node number even on systems that don't have the
stat utility.)

X2SYS_MERGE(1gmt) Generic Mapping Tools X2SYS_MERGE(1gmt)
NAME
x2sys_merge - Merge an updated COEs tables
SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d
DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second
file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This
point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had
to recompute only the COEs between the edited files and the rest of the database.
-A Specify the file main_COElist.d with the main crossover error data base.
-M Specify the file new_COElist.d with the newly computed crossover error data base.
OPTIONS
No space between the option flag and the associated arguments.
EXAMPLES
To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try
x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt
