Hello kiranparsha,

Could you please try following. Let's say following are the Input_files.

cat Input_file1
123456789
1234567891212
1234567

cat Input_file2
jlsjdfkajsjas
jlsjdfkjlsjdfkajsjaqqwewq

paste -d,  Input_file1  Input_file2

Output will be as follows.

123456789,jlsjdfkajsjas
1234567891212,jlsjdfkjlsjdfkajsjaqqwewq
1234567,

So as above you could see if number of lines are not same in Input_file1 and Input_file2 then it should show comma either in starting of the output(When Input_file2 has more lines than Input_file1) or at last of the output(When Input_file1 has more lines than Input_file2), so if you don't want this situation then try following.

paste -d, file1 file2 | sed 's/,$//g;s/^,//g'

Output will be as follows then.

123456789,jlsjdfkajsjas
1234567891212,jlsjdfkjlsjdfkajsjaqqwewq
1234567

Thanks,
