linux - Linux - Diff number of lines in 2 set of files

Question

I have 2 folders which contains 2 set of files.

Folder1

input1.csv
input2.csv
...

Folder2

output1.json
output2.json
...

Ideally, the number of lines in input1 should be same as output1, the number of lines in input2 should be same as output2, and so on.

I need a Linux command to check this automatically and tell me which files are different.

Basically,

If wc -l input1 == wc -l output1, 
    then skip;
else
    show input1 file name (or output1 file name)

repeat for all other files.

How can I achieve this?

这样的事情可能会有所帮助

arr=("1.in" "2.in")
arr2=("1.out" "2.out")

for i in ${!arr[@]}; do  
  v_in=$(wc -l < ${arr[$i]}) ; 
  v_out= $(wc -l < ${arr2[$i]}) ;

  if [ v_in -ne v_out ] then
     echo "not equal"
  else
     echo "equal"
  fi
done
