Start reading a file's content from line N using BASH

Question

Suppose I have the file temp.txt with the following content:

1
2
3
4
5
6

How would you read the file's content starting from line number 3 using BASH so that the output would be like this:

3
4
5
6

Answer 1

tail -n +3 filename 

shows all lines, starting from 3 of filename.

Answer 2

A bash-only solution (for the sake of fun):

#!/bin/bash

C=1

DONE=false

until $DONE ;do
  read LINE || DONE=true

  if [ "$C" -ge "$1" ]; then
    printf "%s\n" $LINE
  fi

  C=$(($C+1))
done
