Generally, the default sort is sorted according to the ASCII of letters. Now I want to sort according to the size of numbers.

There is a file test here with the content:

1. 8723 23423

2. 321324 213432

3. 23 234

4. 123 231

5. 234 1234

6. 654 345234

Sort the first column

1. sort -n test

Sort the second column

1. sort -n -k 2 test

If you change the content of the test file to:

1. 8723,23423

2. 321324,213432

3. 23,234

4. 123,231

5. 234,1234

6. 654,345234

If you want to sort the second column by size

1. sort -n -t "," -k 2 test

If there is no -t option, it is the default space or tab key, so the -t option is not used above.

Use the -r option to sort in reverse order
