Ahnii!
A companion to the packages utility, this tool prints a list of scripts from package.json on the command line.

You can accomplish the same with sed, but it’s quite a command to remember:
sed -n -e '/scripts/,/},/ p' package.json

Check it out at https://github.com/jonesrussell/scripts or simply install it and try:
npm i -g @jonesrussell42/scripts
