unix error: Is a directory

[KasiMaru]

Hi and thanks for the great cli!
I've used it before and everything was ok, but now when I'm -i ./big/* -o ./mini resize 200 I'm getting:

vips__file_open_write: unable to open file "/Users/myname/Desktop/mini" for writing
unix error: Is a directory

Am I doing something wrong?

I'm getting this error too. Trying to convert a png to jpg.

npx sharp-cli -i ~/Desktop/file.png -o ~/Desktop -f jpg

says

vips__file_open_write: unable to open file "/Users/detj/Desktop" for writing
unix error: Is a directory

And specifying a path

npx sharp-cli -i ~/Desktop/file.png -o ~/Desktop/file.jpg -f jpg

says

vips__file_open_write: unable to open file "/Users/detj/Desktop/file.jpg/file.jpg" for writing
unix error: Not a directory

Me too. I'm trying to resize a directory of images so they have a max-width of 100px and am getting the following error (where the output folder ./logos/ already exists):

$ npx sharp-cli -i public/img/logos/*.png -o logos/ resize 100

Hi @pdehaan, you need the specifiy the output files.
npx sharp-cli -i public/img/logos/*.png -o logos/{name}{ext} resize 100 --min

@joejemmely Thanks, that seems to get me closer! I didn't see the --min flag in the README, so I'll try digging through the code and see if I can figure out exactly what it's changing.

It seems like without the --min flag, my logos are now being cropped at 100px wide and 100px high (instead of 100px wide and a variable height w/ aspect ratio). If I do add the --min flag, it seems to resize my images so they are a minimum of 100px high (not just wide), so now some of my logos that were 233x26 (1,985 bytes) get resized up to 896x100 (87,308 bytes).

But as it turns out, specifying --max gives me exactly what I wanted! Thanks again!

For folks stumbling here, following @joejemmely's comment, I solved my issue like this

$ npx sharp-cli -i ~/Desktop/file.png -o ~/Desktop/{name}.jpg -f jpg

And that did the trick! Thanks @joejemmely

I wish the {name}{ext} was mentioned in the documentation and in one the examples...
