創建 ImageMagick Linux 腳本 (Create ImageMagick Linux script)
I have an imagemagick convert command that I use from the shell and I would like to create a linux exec to run it, so I don't have to always run this.
I am converting a PDF file to JPEG files, and this is what I use: convert ‑density 300 *.pdf ‑alpha off ‑scale 1500x2000 ‑quality 70 jpegFiles.jpg
What I would like the linux exec file to do is run the above convert and instead of jpegFiles, to have the actual PDF filename. Of course, for every page jpeg file it would have filename‑0.jpg, filename‑1.jpg, filename‑2.jpg, etc.
I am using Ubuntu. Thank you.

方法 1:
save this in a file and place it in a dir like $HOME/.bin eg. $HOME/.bin/pdf2jpg
for file in "$@"; do
convert ‑density 300 "$file" ‑alpha off ‑scale 1500x2000 ‑quality 70 "${file%.*}‑%d.jpg"
done
make it executable
chmod +x $HOME/.bin/pdf2jpg
and add that dir to the PATH variable
echo "PATH=$PATH:$HOME/.bin" >> $HOME/.bash_profile # assuming you use bash
create a dir named as your pdf along with ‑images suffix and place the files in there
for file in "$@"; do
dir="${file%.*}‑images"
mkdir ‑p "$dir"
convert ‑density 300 "$file" ‑alpha off ‑scale 1500x2000 ‑quality 70 "$dir/${file%.*}‑%d.jpg"
done
