Hey Thanks,

I actually wrote this. I obtained the files and locations from a find command creating the data1 and data2 txt files.


while IFS= read -r line


        grep -q "$cf" ${F1}

        if [ $? == 0 ]

            diff $line `echo $line | sed 's/data2/data1/g' `

            if [ $? == 0 ]
                echo $line 


done < "$F2"

Then I removed them with the below. Most likely a poor way to achieve, however it worked.


for file in `cat duplicate_data`

dFile=`echo $file | sed s/data2/data1/ `

#create md5sum 
mdFile1=`md5sum $file |awk '{print $1}'`
mdFile2=`md5sum $dFile |awk '{print $1}'`

if [ -f $file ]
  if [ $dFile ]
      if [ $mdFile1 == $mdFile2 ]
          echo $file 
          rm -f $dFile


I used a input file to

How simple. I wish I had this before.

Thanks so much for your help.
