Bash Scripting Problem with Imagemagick in Ubuntu 7.04

Andy17MB · 07-09-2007, 04:34 AM

Hi,

I am using a basic Bash script that should run through all the jpeg files in a directory resizing them and writing them to the same filename in a different directory.:

Code:

ls *.jpg | xargs -I FILE convert FILE -resize 1000x1000 hq/*.jpg

This code used to work but now writes all the files to a file in the correct dirtectory called "*.jpg"

I am sure I am doing something daft, I just can't see what. Can anyone help?

Thanks

Andy

Hi.

I believe using *.jpg twice like this works in DOS, but not in a real shell.

You should probably loop with something like:

Code:

for file in *.jpg;
  do
    convert "$file" -resize 1000x1000 hq/"$file"
done

Ilikejam,

Thanks for the pointer. That's a much better way of doing it. I've also got it creating thumbnails in the loop too. Right I'm off to look for some Bash Scripting tutorials to see if I can avoid needing to ask daft questions in future.

Thanks again for the help

Andy
