My file contains 3 columns numbers, like 5 lines data below:
1 811036 395
2 811036 195
1 811036 295
2 811036 95
1 811036 95
I want to sort column 1 in ascending order and column 3 in descending order.
1 811036 395
1 811036 295
1 811036 95
2 811036 195
2 811036 95
I tried the following comment but it failed.
sort -n -k 1 -n -k 3
The command sort -k1,1n -k3,3nr
should work.
It sorts only regarding column one (That's the difference between -k1 and -k1,1) so it can reach the second argument.
Note that sort -k1,1n -k3nr
probably works too.
