using sort command to sort by colums

Question

I have a simple data set. example:

IP address,number of times it appears

192.168.0.10,11
192.168.0.1,15
192.168.0.120,9

I want to use the sort command to sort these by the largest number of times the IP has been seen. the output should look like:

192.168.0.1,15
192.168.0.10,11
192.168.0.120,9

This question is both off-topic and shows no research effort. — chepner, Aug 28 '14 at 16:10
I know its sort -k but after running "sort -k2" I still do not get the desired output. — user3821215, Aug 28 '14 at 16:12

Use -k to specify the column. Don't forget about -n to use numeric ordering.

sort -n -k2 file.txt
