Bash Version: 2.03
Patch Level: 0
Release Status: release

Description:
  I think it would really good if there is a simple example in the
  help-page of "let" which shows how to use it:

  $ i=1
  $ let "i=i+1"
  $ echo $i
  2

  Please include it and help making Unix a little more newbie-friendly.
  It took me more time than necessary to learn. I worked as a Linux teacher
  last week and saw that the pupils had the same problems that I had.

  An other example could be usefull for the "if" command. I was
  thinking about something like this:

  if [ -f foo ]; then
    echo "the file foo exists"
  else
    echo "foo is not here"
  fi

  A link from the help-page for while to the "break" command would
  be usefull, too.

  If you have no time to include these examples I could patch the sources
  and I will send you this patch. Please let me know what you think
