Dear deepakiniimt, I'm a little confused, so please forgive me if I have missed the point. Perhaps putting code tags in your message would help clarity. It seems you may have chopped a bit out too, or i just don't "get it"
You say you have a bunch of files that you expect to be the same apart from a few differences. Could you consider the logic that if one file is the standard, then you could diff each one against it? Something like:-
Would that thinking suffice?
If you are looking for records that are unique in your list of files, then perhaps you should think about:
Find all unique records and capture to a file
Search for those records specifically (maybe edit the file first)
You could:-
Depending on your version of unix, you may need fgrep instead.
If this matches too many lines, then it may be that the lines are sometimes part of larger lines, eg:-
In this case, the last record would match the other three, along with any other record in any file that had the simple string "Hello". You could edit the file of unique records to make them all start with a carat symbol ^ and end with a dollar $ to explicitly signify begginning and end of line and the two ends of your string. You code would grow to:-
It's a bit clumsy and perhaps a sed or an awk would be quicker, just depending how much data you have.
Does that meet your needs, or have I gone off track completely?
I hope that it helps,

Hi,
I want to write a script which will compare the 1st column of both the files and will give the difference.
e.g:-
my 1st file contains:
89 /usr
52 /usr/local
36 /tmp
92 /opt
96 /home

I have to compare two files for any differences, then output the lab and question number for any differences. This is what I currently have:
diff lab2.txt lab2answer.txt > lab2compare.txt
Though the output doesn't have to be sent to a .txt (or any sort of log), I found that easier, at least... (2 Replies)
I have two files like this:
#FILE 1

What to do: Compare the two files and find those lines that doesn't match. And have a new file like this:

Hi there,
I'm sure this question has been asked many times but I can't find any posts with information.
How can I check the differences between say lines 20 - 200 in file1 and lines 420 - 600 in file2?
Thanks in advance for any help!

Hi experts,
I am trying to compare two text files and output the difference to another file.
I'm not strictly looking for differences in text but additional text at the end of one file that isn't in another, so basically comparing the file 2 against file 1 and printing any additional text to... (9 Replies)

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
