envset is a CLI for setting environment variables in .env files.
this is something you may have never considered needing a specialized tool for. and you don't. but just like updating a git config it's more fun with a command.
currently available on homebrew and crates.io

# basic usage, FYI that it prints a diff of the changes to stdout envset KEY1=value1 KEY2=value2 # some env vars are normally very annoying to set, like json or multiline strings. # but envset has your back! envset JSON="$(cat credentials.json)" PRIVATE_KEY="$(openssl genrsa -out /dev/stdout 2048)" # pipe in stdin, useful for copying stuff from one env to another echo -e "KEY1=value1\nKEY2=value2" | envset # heroku users can easily copy parts of their config heroku config -s | grep "^AWS_" | envset # override the default path to a .env file envset -f .env.test KEY1=value1# a few ways to print the current .env envset envset print --json # grab a single value envset get KEY1 # keys only, thanks envset keysenvset delete KEY1 KEY2this cli was thrown together quickly with aider, i also put up a blog post explaining why i made this.
