[CLI] Batch image compression.

I’m trying compress all of image in a folder at once.

So, I’ve execute this command,

squoosh-cli --mozjpeg '{"quality":75,"baseline":false,"arithmetic":false,"progressive":true,"op timize_coding":true,"smoothing":0,"color_space":3,"quant_table":3,"trellis_multipass":false,"trel lis_opt_zero":false,"trellis_opt_table":false,"trellis_loops":1,"auto_subsample":true,"chroma_sub sample":2,"separate_chroma_quality":false,"chroma_quality":75}' -d output ./*

After that Squoosh start compressing the folder images. It’s nicely showing 1.2.3.4.5.6…/17 - image decoding… But in few seconds, it’s gives error and stack on decoding screen.

[Error: EISDIR: illegal operation on a directory, read] {
  errno: -4068,
  code: 'EISDIR',
  syscall: 'read'
}
Worker error:  Error [RuntimeError]: abort(Error: EISDIR: illegal operation on a directory, read). Build with -s ASSERTIONS=1 for more info.

For me works without the star, just like these:

npx @squoosh/cli --mozjpeg ‘{“quality”:60}’ -d Squooshed ./

BTW, To do it from .bat you have to do it without the single quotes, like this:

npx @squoosh/cli --mozjpeg {“quality”:60} -d Squooshed ./

Windows 10. Node v14.15.1 Squoosh CLI v0.7.2

Yeah, I have heard that the CLI is currently causing problems on Windows. I’ll look into this.
