How can I sort file names by version numbers?

Question

In the directory \"data\" are these files:

command-1.9a-setup
command-2.0a-setup
command-2.0c-setup
command-2.0-setup

Answer 1

I have files in a folder and need to get those name in sort order, based on the number. E.g. -

abc_dr-1.txt
hg_io-5.txt
kls_er_we-3.txt
sd-4.txt
sl_rt_we_yh-2.txt

I need to sort them based on number. So I used this to sort.

ls -1 | sort -t '-' -nk2

It gave me files in sort order based on number.
