I have a file like so:

1.1
3.2
1.2
1.10

I would like to sort the file so that it looks like so:

1.1
1.2
1.10
3.2

In other words, 1.10 is bigger than 1.2

I tried:

sort -nk 1,1 file

But I keep getting this, which is not what I want

1.1
1.10
1.2
3.2

Thanks

回答1:

With GNU sort:

sort -t "." -n -k1,1 -k2,2 file

Output:

1.1
1.2
1.10
3.2

You may use the -V option.

sort -V numbers

However this option is only in GNU Coreutils and could be absent from other implementation.
