Спасибо @ Mickaël, за твое потрясающее решение,
Я создал небольшое улучшение для управления страницей разделения -> действие по умолчанию и несколько примеров для инструмента -
https://github.com/Elia-Sh/toolsAndUtils/blob/master/pdfSplit.sh
сохранить файл -
#!/bin/bash
# inspired by:
# /superuser/293856/reducing-pdf-file-size
# https://www.ghostscript.com/doc/current/Use.htm#File_output
usage() {
cat<<EOF
Usage:
${0} <input file> <output file> [screen|ebook|printer|prepress]
EOF
}
# Examples:
# Note: Ghostscript must be installed on your system
# Note that <n> represents the number of pages in the original document;
# * Only split file to pages; no range available -
# \$ ${0} someFile.pdf
# will create the following single page files:
# someFile_page_0001.pdf, someFile_page_0002.pdf someFile_page_0003.pdf, someFile_page_000<n>.pdf
# * Split page to custom output file name -
# \$ ${0} someFile.pdf newFileName_pageNumer_%2d.pdf
# will create the following single page files:
# newFileName_pageNumer_01.pdf, newFileName_pageNumer_02.pdf, newFileName_pageNumer_03.pdf, newFileName_pageNumer_0<n>.pdf
# * Only reduce quality of pdf file !without! splitting -
# \$ ${0} someFile.pdf newFileName.pdf ebook
# will create the following single file: newFileName.pdf with reduced quality
# * Reduce quality !and! split pdf to single pages -
# \$ ${0} someFile.pdf newFileName_%2d.pdf ebook
# will create the following single page files, with lower qualuty
# newFileName_page_01.pdf, newFileName_page_02.pdf, newFileName_page_03.pdf, newFileName_page_0<n>.pdf
