我需要一个非常简单的shell脚本来处理文件夹上的所有图像并更改其大小。图像处理是使用gimp script-fu完成的,shell脚本必须做的唯一事情是for循环。
我做到了:
#!/bin/sh
mkdir processed
for image in `ls`
do
if [ $image != "script.sh" ]
then
if [ $image != "processed" ]
then
gimp -i -b '(let* ( (img (gimp-file-load 1 "1.jpg" "1.jpg")) (drw (gimp-image-get-active-drawable (car img))) ) (gimp-image-scale-full 1 400 300 3) (file-jpeg-save 1 (car img) (car drw) "processed/1.jpg" "1.jpg" 0.6 0 1 1 "" 3 0 0 2) (gimp-quit 0) )'
fi
fi
done
这段代码有效但是,在脚本fu代码中我把1.jpg作为文件名,当然,我希望看到$ image变量的值。我的shell脚本知识是有限的,我失去了我必须将变量放在命令中的方式。
你能帮帮我吗?谢谢你的时间:))答案 0 :(得分:2)
使用for image in *
代替ls
。
要将变量传递给Gimp脚本并保留Gimp的引号,您需要对外部引号使用双引号并转义内部引号:
gimp -i -b "(let* ( (img (gimp-file-load 1 \"$image\" \"$image\")) (drw (gimp-image-get-active-drawable (car img))) ) (gimp-image-scale-full 1 400 300 3) (file-jpeg-save 1 (car img) (car drw) \"processed/$image\" \"$image\" 0.6 0 1 1 "" 3 0 0 2) (gimp-quit 0) )"
您还可以简化脚本:
mkdir processed
for image in *.jpg
do
if [[ -f $image ]]
then
gimp ...
fi
done
如果您想要添加更多扩展程序:
for image in *.{jpg,JPG,jpeg,JPEG,gif,GIF,png,PNG}

另一种可能更具可读性的方法:
mkdir processed
gimp_script_template='(let* (
(img (gimp-file-load 1 "%s" "%s"))
(drw (gimp-image-get-active-drawable (car img)))
)
(gimp-image-scale-full 1 400 300 3)
(file-jpeg-save 1 (car img) (car drw) "processed/%s" "%s" 0.6 0 1 1 "" 3 0 0 2)
(gimp-quit 0)
)'
for img in *; do
[ ! -f "$img" ] && continue
[ "$img" = "script.sh" ] && continue
gimp_script="$( printf "$gimp_script_template" "$img" "$img" "$img" "$img" )"
gimp -i -b "$gimp_script"
done

你可以尝试
"'(let* ( (img (gimp-file-load 1 "$image" "$image")) (drw (gimp-image-get-active-drawable (car img))) ) (gimp-image-scale-full 1 400 300 3) (file-jpeg-save 1 (car img) (car drw) "processed/$image" "$image" 0.6 0 1 1 "" 3 0 0 2) (gimp-quit 0) )'"
