#!/bin/bash

MINIMUM_WEIGHT=$1
if [ -z $MINIMUM_WEIGHT ]; then
  MINIMUM_WEIGHT=0
fi

for FILE in `find ./content -type f | grep .md`
do
  CURRENT_WEIGHT=`grep -E 'weight:\ \d+' $FILE | cut -d" " -f2`

  if [ -z $CURRENT_WEIGHT ]; then
    echo "⚠️ $FILE não tem weight ⚠️"
    continue
  fi

  if [ "$CURRENT_WEIGHT" -gt "$MINIMUM_WEIGHT" ]; then
    echo "PESO $CURRENT_WEIGHT -  ARQUIVO: $FILE"
    perl -i  -pe 's/weight: \K\d+/$&+1/e' $FILE
  fi
done

Oh, it should be executed from the root of the Hugo repository. 😅
