Hi I'm comparing same files names which are in different folders .
The first for loop for the files in DAY1 folder and
the second for loop for the files in DAY2 folder .
the first IF condition is for checking whether the file names are equal
the second If condtion is for checking the content is same or not
if the content is same then remove all the files from DAY1 Folder at a time .
No need to loop around from then
So I've written the BREAK statement .

Code:

src_file="/home/etc/day1"
dst_file="/home/oetc/day2"
for i_day in $src_file/dfl*
  do
     for j_day in $dst_file/dfl*
        do
             if [ $i_day = $j_day ]
                then
                    if diff $i_day $j_day >/dev/null ; then
                        rm $src_file/dfl* 
                        break
                    fi
             fi
     done
done

Now the issue is the BREAK statement . How to terminate the main for loop if the 2nd IF condition is satisfied .

Thanks
