Shell Programming and Scripting

Hi,

I am having two folders where i need to compare the content of files and also to know if any new files been added and redirect the difference output in respective filename logs. For e.g.:

Code:

Directory D1:
f1
f2
f3

Directory D2:
f1
f2
f3
f4

i Need to compare the directories D1 and D2 and write it respective file log of there are any difference and if any additional file added write in another log file

Output content in the log file

Code:

f1.log - There is a difference in the f1 and f2, please find the below difference:
......
f2.log - No difference found
f3.log - No difference found
Additional.log - There is additional file in D2 with filename as f4

I tried using below code:

Code:

diff -arq D1 D2

And what did it do?

I am able to get only the outputs as showing there is file difference and additional file present in D2 i need to print the difference like how it can be achieved in respective log

-q stops it from printing a lot of the information you want, remove that.

That even with diff -r i can able to achieve but i need to right the log so that it would be tracked

Show the output you have and I can try and convert it into the format you want.

I tried something like this

Code:

cd D1
for i in *
do
diff $i D2/$i >> $i.log
done

But couldn't able to work as my desired output
