Compare file extension from two different txt file and find the differences.

Neal000 · 08-27-2012, 01:51 PM

I am new to create scripts.

Please help me to prepare one script.
The scenario is : I have two files.
file1 and file2.

file1
doc1.doc
doc2.doc
doc3.txt

file2
doc1.doc
doc2.rtf
doc3.exe

I have to compare each row of both the file, and get the result if the extension is not matching.

o/p shud be.
doc1.doc - ext. match
doc2.doc - ext. not match
doc3.txt - ext. not match.

Try this...

Code:

paste $InFile1 $InFile2 \
|awk '{if ($1==$2) print $1, "ext. match";
       else print $1, "ext. not match"}'

Hi and welcome to LQ.

What have you done so far? Can you show us your script and where you are stuck?

Hi Neal000

Please exhibit something showing that indeed, you tried to do your homework yourself.

Doing it for you won't make you learn anything.

You are right. I gave a solution without recognizing the question as homework. Shame on me!

Thanks Daniel, Actually this is my first script. and I only know some basic commands of linux. I was thinking that this code need some looping concept, I had stuck at beginning only, how to define two different file in loop.

No loop required. The paste combines two files to look like this ...

Code:

doc1.doc doc1.doc
doc2.doc doc2.rtf
doc3.txt doc3.exe

... and the awk compares the first word (that's $1) with the second word (that's $2) in each line and outputs the desired text.
