I draw a lot with Clip Studio Paint, wich works almost flawlessly with wine, but the only major caveat is that the original files are in a format that doesn't have thumbnail support in linux (as far as I can tell).



For most files I will have 2 versions. File.clip (the CSP format) and File.png. I would like to use .png (or its thumbnail) as a thumbnail for File.clip.



So, how would you add a thumbnail to a random file from the command line?



Im working in ubuntu 18.04 and nautilus.



Edit: Changed the description of what I want to do exactly to make it clearer.

Ok, so as i understand it, you are seeking to create a thumbnail of a file by using a different file (created predictably).



We can try something like this:



#!/bin/bash

# Based on CC-BY 2016 Marcin Kaminski https://askubuntu.com/users/98096/marcin-kaminski
# https://askubuntu.com/a/201894/216568

# USAGE: mkthumb.sh [-s] [-r] <path> [path]
# create nautilus thumbnails for clips in the directories (and their
# sub-directories) given as parameters.
# -s is used to skip generating thumbnails that already exist

skip_existing=0
if [[ "$1" == "-s" ]]; then
skip_existing=1
shift
fi

maxdepth="1"
if [[ "$1" == "-r" ]]; then
maxdepth="9999"
shift
fi

mkImageThumb()
size="$3"
file="$1"
dest="$2"
convert -thumbnail $sizex$size "$file[0]" "$dest" &>/dev/null
if (( $? == 0 )); then
echo "OK $file [$dest]"
else
echo "FAIL $file"
fi


OLDIFS="$IFS"
IFS=$'n'
for dir in $@; do
realdir=`realpath "$dir"`
echo "Processing directory $realdir"
for file in $(find "$realdir" -maxdepth $maxdepth -regextype posix-egrep -iregex '.*.clip'); do
md5=$(echo -n "$file" | perl -MURI::file -MDigest::MD5=md5_hex -ne 'print md5_hex(URI::file->new($_));')
image=$(dirname "$file")/$(basename "$file" .clip).png
dest="$HOME/.cache/thumbnails/normal/$md5.png"
if [[ ! -f "$dest" || "$skip_existing" != "0" ]]; then
mkImageThumb "$image" "$dest" 128
else
echo "SKIP $file"
fi
dest="$HOME/.cache/thumbnails/large/$md5.png"
if [[ ! -f "$dest" || "$skip_existing" != "0" ]]; then
mkImageThumb "$image" "$dest" 256
else
echo "SKIP $file"
fi
done
done
IFS="$OLDIFS"


This script will take the whole directory and generate the needed thumbnails (i haven't tested the script now, but it should).

@metichi Could it be that nautilus has changed its location for thumbnails? I don't use that file manager, can you double check that other thumbnails are being generated there?

There seems to be plenty of other thumbnails in that folder

@metichi Ok, i'm not sure what it can be. Are you viewing the directory in icon mode?

Not 100% sure what icon mode is, but the .png files have their thumbnails alright. Anyway, that script does help a lot and is a great thing to help me understand what's going on and go look for other stuff. Thank you for all the help so far!
