MD5 sum check


Hey guys,

I have had this question answered before on this site, but like a dummy I did not save my script.


I'm trying to write a bash script that points to a file server to check for duplicate files. I have done some googling, but I see to be stuck on an if statement.


here is what I have so far:

"#!/bin/bash
#This is a script to find duplicate files using Md5sum

SRC_DIR=/directory/home/user/NOTES/
RESULT_FILE=/directory/home/home/checksum_result.txt
FAILURE=/directory/home/user/checksum_fail.txt
SUCCESS=/directory/home/user/checksum_win.txt
cd $SRC_DIR
find ./ -type f -exec md5sum {} \; > /directory/home/user/checksum.txt
md5sum -c < /directory/home/user/checksum.txt > $RESULT_FILE
if [ "$file1" != "$file2" ];

then"

This is where I get stuck.

" if [ "$file1" != "$file2" ]; "

I'm not entirely sure if the IF statement is correct. I want it to compare the checksum.txt file to the RESULTS file, then print the duplicates into a checksum_fail.txt file.

For starters, you need to setup the variables for $FILE1 and $FILE2; or show that part of the script, because right now those variables do not exist at the point which you are comparing them.

Please place your code within [code] tags.

There is a logical error here. An md5sum is only accurate if two files have the same size. Two md5sums can be the same for two files of different size.
