apoorva joshi — Thu, 18 Sep 2014 03:10:44 -0400

Hi, I have to compare two .csv files and get the output in other file in the given format.

First column in provided files would be unique.

If a new line is added I want A followed by "," and then followed by entire new row. If a line is modified I want C followed by "," and then followed by entire modified row. If a line is deleted I want D followed by "," and then followed by entire deleted row.

File 1

aa, bb, cc, dd, ee

bb, ww, ee, tt, yy

cc, vv, vv, vv, vv

File 2 bb, ww, ee, tt, y1

cc, vv, vv, vv, vv

nn, bb, nn, cc, bb

So output be like

D, aa, bb, cc, dd, ee

C, bb, ww, ee, tt, y1

A, nn, bb, nn, cc, bb

Can't set up nameservers in Centos 6.3

Cosmosurf Dotnet — Sat, 05 Jan 2013 08:32:16 -0500

I have a web server running Centos 6.3. I cannot seem to find any information on how to setup my name servers. /etc/resolv.conf looks like this: 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 96.235.41.91 ns1.luloot.net ns1 71.252.0.12 ns3.luloot.net ns2 71.250.0.12 ns2.luloot.net ns3 My name servers are not pointing to their IPs. As a result, the hostname ns1.luloot.net is not resolving even when using the server IP "96.235.41.91" in a web browser. I am stuck. Please help. Thank you!

Is there any shell script or software available to watch a CSV file?

tanveer — Wed, 18 Jul 2012 03:23:26 -0400

I am using CentOS 5.5. There is a CSV file in a particular directory(/somewhere/somefile.csv) where a software continuously appending comma separated row(s) of data time to time and the file size is growing big (currently it's 50MB+).

My idea is to create a demon to watch the CSV file. Whenever any row(s) of data appended in that CSV file the demon will read the last appended row(s) and create/write it in a separate text file by date.

I would like to know:

Is there any shell script/software available on this regards to watch a CSV file?
Is there any better idea or solutions other then create a demon?

I have googled tons of time but didn't find any good idea/solution(s). Please help.

Thanks in advance.
