basic bash stuff that I'm tired of searching whenever I need ¯\_(ツ)_/¯

bash-tldr.sh

# return a value in a function
function returnTrue() {
    echo true
}

# pass arguments to a function
#
# usage:
# $ greeter "Gabriel"
# > "Hello Gabriel"
function greeter() {
    echo "Hello $1"
}

# assign function result to a variable
thing="$(greeter 'Gabriel')" # Hello Gabriel

# Compare strings and variables
if [[ "$thing" == "false" ]]; then
    echo "yes"
else
    echo "no"
fi
