Resize (*.jpg) -> Rename -> Compress (xyz.tar) ?
 

Hello there

I am looking for a single line command that does the following:

1) Resize all *.jpg files in a given folder using convert function from imagemagick
2) Append the resized file names with _resized before the .jpg extension.
3) Create and pipe this data to a tar archive.

The following command resizes the images but I do not know how to proceed?

find . -name "*.jpg" -exec convert '{}' -resize 800x600 '{}' \;

Thank you very much

Okay there is an improvement:

for i in `ls *.jpg`; do convert -resize 800x600 -quality 90 $i resized_$i; tar -rvf pics.tar conv_$i; done

But I still do not want the files to be created, and would rather forward the stream directly to tar. Any help??

Okay here is my solution:

for i in `ls *.jpg`; do convert -resize 800x600 -quality 90 $i resized_$i; tar -rvf pics.tar resized_$i; rm resized_$i; done

Perhaps someone can do better?

You don't need to use ls in the for loop:The - in the convert command sends the output to standard output, and then it's piped into tar, whereupon tar reads in standard input instead of a bunch of file names.

edit: I'm a dunce. This doesn't work, but I don't know why. However, the part about not needing ls is true :D

Yes I just tried but to no avail. But thanks for the ls tip.

Yes, try "mogrify" - "convert" does the image manipulation and writes to a new file; mogrify manipulates the file itself.

Thanks but that does not solve the issue as I do not want to modify the original files.
