valor - Cómo salir de una función en bash

llamar funciones en shell

Question

¿Cómo saldría de una función si una condición es verdadera sin matar toda la secuencia de comandos, simplemente regrese a antes de llamar a la función.

Ejemplo

# Start script
Do scripty stuff here
Ok now lets call FUNCT
FUNCT
Here is A to come back to

function FUNCT {
  if [ blah is false ]; then
    exit the function and go up to A
  else
    keep running the function
  fi
}

Answer 1

Usar operador de return :

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

Answer 2

Utilizar:

return [n]

De help return

return : retorno [n]

Return from a shell function.

Causes a function or sourced script to exit with the return value
specified by N.  If N is omitted, the return status is that of the
last command executed within the function or script.

Exit Status:
Returns N, or failure if the shell is not executing a function or script.
