I am using a database text file with a field that increments +1 with each new entry, occasionally if a entry is deleted the unique sequence is disrupted.
I am looking for a small script/function in sh and/or perl that would re index this.
Example of db file:

I have a csv flatfile with a few million rows. I need to replace a field (field number is 85) in the file with a sequential number.
As an example, let's assume there are only 4 fields in the file:

hwloc-gather-topology
HWLOC-GATHER-TOPOLOGY(1) hwloc HWLOC-GATHER-TOPOLOGY(1)NAME
hwloc-gather-topology - Saves the relevant Linux topology files and the lstopo output for later (possibly offline) usage.
SYNOPSIS
hwloc-gather-topology [options] <path>
OPTIONS -h --help display help message and exit
DESCRIPTION
hwloc-gather-topology saves all the relevant topology files into an archive (<path>.tar.bz2) and the lstopo output (<path>.output). The
utility for example stores the /proc/cpuinfo file and the entire /sys/devices/system/node/ directory tree.
These files can be used later to explore the machine topology offline. Once the tarball has been extracted, it may for instance be given
to some hwloc command-line utilities through their --input option. It is also possible to override the default topology that the hwloc
library will read by setting the extracted path in the HWLOC_FSROOT environment variable.
Both archive and lstopo output may also be submitted to hwloc developers to debug issues remotely.
hwloc-gather-topology is a Linux specific tool, it is not installed on other operating systems.
NOTE: It is highly recommended that you read the hwloc(7) overview page before reading this man page.
EXAMPLES
To store topology information to be used later (possibly on a different host) please run:
hwloc-gather-topology /tmp/myhost
It will store all relevant topology files in the /tmp/myhost.tar.bz2 archive and the lstopo output in the /tmp/myhost.output file. These
files can be transferred on another host for later/offline analysis and/or as the input to various hwloc utilities.
To use these data with hwloc utilities you have to unpack myhost.tar.bz2 archive first:
tar jxvf /tmp/myhost.tar.bz2
A new directory named myhost now contains all topology files. Then you ask various hwloc utilities to use this topology instead of the one
of the real machine by passing --input myhost. To display the topology just run:
lstopo --input ./myhost
It is not necessary that the topology is extracted in the current directory, absolute or relative paths are also supported:
lstopo --input /path/to/remote/host/extracted/topology/
To see how hwloc would distribute 8 parallel jobs on the original host:
hwloc-distrib --input myhost --single 8
To get the corresponding physical indexes in the previous command:
hwloc-calc --input myhost --po --li --proclist $(hwloc-distrib --input myhost --single 8)
Any program may actually override the default topology with a given archived one even if it does not have a --input option. The
HWLOC_FSROOT environment variable should be used to do so:
HWLOC_FSROOT=myhost hwloc-calc --po --li --proclist $(hwloc-distrib --single 8)
All these commands will produce the same output as if executed directly on the host on which the topology information was originally gath-
ered by the hwloc-gather-topology script.
RETURN VALUE
Upon successful execution, hwloc-gather-topology will exit with the code 0.
hwloc-gather-topology will return nonzero exit status if any kind of error occurs, such as (but not limited to) failure to create the ar-
chive or output file.
