Ferramenta Shellscript com GUI
Eu modifiquei uma ferramenta de shellscript, que pode criar uma lista de imagens selecionadas selected.txt . Você pode usar a tecla Enter para selecionar uma imagem ou a tecla Escape para ignorá-la.
Você também pode refazer a seleção anexando arquivos à lista e pular os arquivos restantes com a janela "Ignorar outras fotos".
Os seguintes arquivos são criados (no diretório atual)
names.txt # a list of all the files in the current directory tree
list.txt # a working list of selected files, that may contain duplicates
selected.txt # the final list of selected files
Você precisa do visualizador feh para mostrar as imagens e xterm para ajudar a obter a janela com a pergunta no topo (de acordo com testes no Kubuntu e no Lubuntu).
sudo apt install feh xterm
O shellscript é testado em
- Lubuntu e Ubuntu 16.04 LTS
- Ubuntu 17.10
- Kubuntu Bionic (18.04 LTS).
Aqui está o shellscript:
#!/bin/bash
# Copyright 2018 Nio Wiklund

# GPLv3: GNU GPL version 3
#
# This shellscript works with files in the current directory and its
# subdirectories. There is also an assumption that you
#
# batch resize the files to jpg and/or png files.
#
# This can be modified in the lines starting with 'find'
#
# You may need to select another 'sleep time' in order to
# get the question window on top of the picture window,
# if the files load slowly into the file viewer 'feh'.
