linux sort Multi field sort instance resolution

This paper focuses on linux sort multi-field sorting, which is described as follows.

The sort program, which comes with most Linux distributions, is very powerful, except for multi-field sorting

sort has a parameter -ES11en, which specifies fields, has a more complex syntax, and is outside the text range.

Below 1 is 1 section of data (obtained from the gene, only as demo), and the file name is data

Fields are separated by Spaces

Now you want to first sequence the genes by chromosome, then the genes on the same chromosome by their starting sites, so this is a multi-field sequence, and the second field is a number, using the sort command as follows

sort -t ' ' -k1,1 -k2n,2 data

Where -t "specifies a column delimited with a space

-k1,1 specifies the keyword sorted by column 1 -k2ES53en,2 specifies data sorting by the second column keyword

You can also use

sort +0 -1 +1n -2

The effect is one.
