Hey u can use in simple version like this,
File.awk :
BEGIN {
FS=":"
}
FNR == NR { if (FNR==1) file1=FILENAME; arr[NR]=$0; next }
{
if ($0 != arr[FNR])
printf("%s\n", $0)
else
printf("%s\n",arr[FNR])
}
To run the above awk,
nawk -f File.awk << File 1 >> << File 2 >>
Redirect the above output to <<File 3>>
Then finally mv the File 3 to File 1.
