With shell builtins (no external command awk, sed, perl)
here is a standard procedure
Code:
fn="file.conf"
# split on =, change the certain value, write to .new file:
while IFS="=" read key val
do
  case $key in
  "Another Setting") val=27;;
  esac
  printf "%s\n" "$key=$val"
done < $fn > $fn.new
# If successful
if [ $? -eq 0 ]
then
  # copy back to the original file; if successful delete the .new file
  cp $fn.new $fn &&
  rm $fn.new
fi
