I’m on Mac (14.4) and I use fish shell. I did curl https://sprites.dev/install.sh | bash and I don’t have a “sprite” command in fish, for obvious reasons. I tried curl https://sprites.dev/install.sh | fish and it errors.
fish isn’t a POSIX shell, so you might need to set up the path yourself. the curl https://sprites.dev/install.sh | bash command tells you where it installs the sprite binary (for me it’s /Users/lillian/.local/bin), so adding that directory to your fish’s PATH will let you use sprites CLI from fish.
