Simple little bash function to search file for a section of text when you only now the start and end of the sections (Used to search postgresql database dumps)

findBlob.sh

#// Searchs a file for a blob (section)
#// and returns what it finds in a array
#//
#// PARAMS:
#//   $1 String  - The name of the file to search
#//   $2 String  - The upper bound (start) of the blob
#//   $3 String  - The lower bound (end) of the blob
#//   $4 Boolean - Defines if the contense of the bounds should be included in the results
findBlobInFile() {
  mapfile -t lines < <(cat $1)
  upperBound=$2
  lowerBound=$3
  addLines=false
  grabedLines=()
  [ -z "${4}" ] && includeBounds=false || includeBounds=$4
    
  for lineIndex in $(seq 0 $[${#lines[@]} - 1]); do  
          line=${lines[$lineIndex]}

          if [[ "${line}" == "${upperBound}" ]] || [[ "${line}" == *"${upperBound}"* ]]; then 
                  addLines=true
                  $includeBounds && grabedLines+=("$line")
          elif [[ "${line}" == "${lowerBound}" ]] || [[ "${line}" == *"${lowerBound}"* ]]; then if $addLines; then
                  addLines=false
                  $includeBounds && grabedLines+=("$line")
          fi; elif $addLines; then
                  grabedLines+=("$line")
          fi

  done

  echo "$(declare -p grabedLines)"
