resulting img file not divisible by 512bytes

[ghost]

After I run pishink, the resulting img file can not be used in the Raspberry Pi Imager. The error is that the img is not in 512 byte increments. I can use the image in BalenaEtcher. I guess that program is not as picky. How do I fix this so the image works in the Raspberry Pi Imager application?

I've never run into that issue actually. You can pad the file with anything to get it to a nice 512 byte block and that should fix it.

I'm going to leave this open to try and add it as a feature.

Dumb question, how would I pad it?

this worked for me:

size=$(stat -f '%z' test.img)                   
pad_size=$(( 512 - $size % 512 ))               
dd if=/dev/zero of=test.img bs=1 count=$pad_size seek=$size
