如何在 bash 脚本中将一个文件夹中的所有 tif 文件转换为 pdf 并保存在另一个位置而不循环？

Question

find /home/folder1/folder2/folder3/my\ Raw\ Data/"$1"/"$2"/"$3"/"$4" -type f -name "*.tif" -exec bash -c 'tiff2pdf "$1" -o "${1%.tif}".pdf' - '{}' \;

This is my bash script to convert tif files in /home/folder1/folder2/folder3/my\ Raw\ Data/"$1"/"$2"/"$3"/"$4" to pdf.The output pdf will also get saved in same location, But I want the output pdf in /home/folder1/folder2/folder3/my\ Raw\ Data/"$1"/"$2"/"$3"/backup . How is it possible without using a loop? Is there any solution for this?

Answer 1

Here's a way to get them all done in parallel, without any loops, using GNU Parallel :

cd /path/to/tiffs && parallel tiff2pdf {} -o ../backup/{.}.pdf ::: *tif

Try like this first to see what it would do, without doing anything:

cd /path/to/tiffs && parallel --dry-run tiff2pdf {} -o ../backup/{.}.pdf ::: *tif

Here's another way with ImageMagick :

cd /path/to/tiffs && magick mogrify -path ../backup -format PDF *tif
