I'm making an script that gives me a day like this jjj/yyyy when I give it a day like this dd/mm/yyyy and I need it to have an error when you don't write correctly but I'm starting and it's not working :(

#! /bin/bash

#Primero debes ingresar el mes
echo "Ingresa el número de un mes del año"
read mes

#Condicional 
#Dependiendo si coloca bien $mes
if [ "$mes" -lt 12 -a "$mes" -gt 0 ]; then
echo "muy bien, sigamos."
    else
    if [ "$mes" -gt 12 -a "$mes" -lt 0 ]; then
    echo "Creo que eso ya no es un mes!";
exit
fi

When I run it it says "syntax error near unexpected end of file"

  • Yes, someone can help you. – Anthon Sep 12 '14 at 4:05
  • Your code doesn't make sense. A number cannot be at the same time less than 0 and greater than 12, so your second condition can never be true. Also note that -lt and -gt are for strictly greater. -lt 12 and -gt 0 means from 1 to 11. Use -le for less than or equal. – Stéphane Chazelas Jul 28 '16 at 7:33

You missed a fi for inner if:

if [ "$mes" -lt 12 -a "$mes" -gt 0 ]; then
  echo "muy bien, sigamos."
else
  if [ "$mes" -gt 12 -a "$mes" -lt 0 ]; then
    echo "Creo que eso ya no es un mes!"
    # Missed fi here
  fi
  exit
fi

  • Now I have another issue, it doesn't display the second if part... I mean, If I put the number 13 it just ends, it doesn't say "Creo que esto ya no es un mes!" – Divshah Sep 12 '14 at 4:24
  • @Divshah: 13 is not greater than 12 and less than 1 – cuonglm Sep 12 '14 at 4:26
  • @Divshah, change your -a flag in the second if loop to -o. – Ramesh Sep 12 '14 at 4:27

  • you can find it in a new answer... please help :( – Divshah Sep 12 '14 at 5:27

In the else if statement, you need to write it like this:

elfi [con]; then echo "statement"
