let the first file be a.txt ,second be b.txt and the third one (final file) be c.txt

The command would be

cat a.txt b.txt | sort -u >c.txt

cat a.txt b.txt will combine the two files (with duplicates)

| (pipe) will take the output of the previous command and send it as input the next command sort -u

sort -u will sort it in ascending order taking only the unique values

sort -u > c.txt will send the sorted unique values to c.txt file

cat a.txt,b.txt give 1 2 3 4 5 6 5 6 7 89 10

sort -u will give 1 2 3 4 5 6 7 8 9 10

this output is then stored in c.txt

hope this was what you were looking for
