Any ideas how?

ls will re-sort the filenames you give it (or the current directory, if you don't) itself; one way around this would be to give it the filenames separately:

ls -l *.d? ; ls -l *.d??

Or, since you appear to have an alias/function to do a long listing:

ll *.d?; ll *.d??

I don't know what your ll is. ll is a commonly given alias to ls -l, but that doesn't look like it.

In any case, that particular output could be sorted in the order you want with GNU sort and its version sort applied to the 5th column and over:

ll | sort -bVk5

If ll is somehow an alias to ls and your ls is GNU ls, then that ls also has a version sort enabled with -v.

With the zsh shell, you can have its globs sorted in a similar fashion with the numericglobsort option or the (n) glob qualifier. So if your ll command can get the list of file names as argument and doesn't do any further sorting itself, you could do (in zsh, and zsh only):

ll *(n)

Using sort:

$ ls -lghFG | sort -n -td -k2
total 0
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d1
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d2
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d3
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d4
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d5
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d6

-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d8
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d9
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d10
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d11
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d12
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d13
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d14
-rw-r--r-- 1 0 Aug 3 09:43 tig_10.d15

This will use the letter d as a delimiter and sort the output numerically on the field 2 so there could be issues if your filenames contain the letter d.

To meet your requirement of using ll (which is an alias) you could do (not recommended:

alias ll='ls -lghFG | sort -n -td -k2'

from man,

ll -v

• -v natural sort of (version) numbers within the text
