Sxiv: [feature request] Load all images in the same folder

sxiv is designed for command line users. Please use a wrapper script for that. Google sxiv-rifle or use the following one:

#!/bin/sh

if [ $# -ne 1 -o ! -f "$1" ]; then
    echo "usage: ${0##*/} FILE" >&2
    exit 1
fi

file -i "$(dirname "$1")"/* \
    | awk -F ': *' -v f="$1" '
        $2 ~ "^image" {
            files[cnt++] = $1;
            if ($1 == f)
                n = cnt;
        }
        END {
            for (i = 0; i < cnt; i++)
                print files[i] | "sxiv -i -n " n;
        }'

It would be good if -n option can also take "file name" instead of just "index number", like opening a file manager with a specific file selected. With this, you can use something like sxiv -n x.png *.png

EDIT: Just noticed that there is already a pull request (https://github.com/muennich/sxiv/pull/371).

My workaround for this:
