I wonder if comparison is like this.

cata.txt | while read LINE_A
do
  cat1.txt | while read LINE_1
  do
    printf "${LINE_A} and ${LINE_1}"
    printf "Comparison"
    if ["${LINE_A}"="${LINE_1}"] 
    then
      printf "Same thing"
    else
      printf "Something Different"
    fi
    It was echo.
  done
done

join-j65535-t"-"a.txt1.txt | sed-e"s/^-//">merge.txt

Supplement to emasaka's response.
Specify delimiter and delete delimiter at the beginning of the line and output it to a file

For Linux, if you specify a column that does not exist in the join command, you get a combination of lines of text.

$join-j100 a.txt1.txt
 a1
 a2
 a3
 a4
 b1
 b2
 b3
 b4
 c1
 c2
 c3
 c4
 d1
 d2
 d3
 d4
