There is no option in ls to filter on filename but in most of the shells there are globbing extension man bash /Pattern Matching

ksh

ls -lrtd -- *@(day|night)*

zsh

setopt extendedglob
ls -lrtd -- *(day|night)*

or:

setopt kshglob
ls -lrtd -- *@(day|night)*

bash

shopt -s extglob
ls -lrtd -- *@(day|night)*

In any of these three shells you can do this, but note that if one of the cases doesn't match any file, that pattern will be left unexpanded (e.g. *day* night1.txt othernight.txt if there is no file name containing day):

ls -lrtd -- *{day,night}*

In any shells you can do:

ls -lrtd -- *day* *night*

In zsh, if there's either no day or night file, the last two commands will fail; set the nonomatch or csh_null_glob option, or add (N) after each pattern to avoid this.

In all shells, you can do:

ls -lrtd -- *day* *night*

though in zsh if there's either no day or night file, the whole command will fail (see the nonomatch and csh_null_glob options).
