Defining functions

myfunc() {
    echo "hello $1"
}

Same as above (alternate syntax)

function myfunc {
    echo "hello $1"
}

myfunc "John"

Returning values

myfunc() {
    local myresult='some value'
    echo "$myresult"
}

result=$(myfunc)

Raising errors

myfunc() {
  return 1
}

if myfunc; then
  echo "success"
else
  echo "failure"
