commandline tools: making my life easier every day

You know what I really love? ImageMagick.

I just started a process creating use JPEG images out of 4000 high-quality TIFFs. One line of bash, and now it will run for a while, and I can go do something else.

Share, please. I'm embarking on a similar project with a PDF of page images as the desired end result. What options are you using?

I'm doing convert -resize 800x800 -compress jpeg -quality 90 [filename].tif [filename].jpg, run through a for loop in bash to get everything. Man, *slow*, though, especially on the 45MB TIFFs. *g*

My only problem is that the old set of JPEGs was listed as "compressed at a 10:1 ratio", and a day of image research doesn't even tell me if that's a meaningful or repeatable metric. Some websites imply that it's not. Certainly the ImageMagick "quality" switch is IM-specific. But if there's a way to make ImageMagick "compress at a 10:1 ratio" -- or even if that's a meaningful command -- I can't find it.
