Thanks for the report.  However, this is not a bug in 'echo', but a
feature of your shell.  At least bash has a notion of history expansion,
where double-quoted ! is a shortcut for injecting previously-typed
commands from your history into the current command invocation.  Read
'man bash' and search for "history" for details.

History expansion occurs BEFORE 'echo' sees its command line arguments.
 You'd get the same effect with ANY OTHER COMMAND, when given the same
argument.  Thus, this is not a bug in coreutils, and I'm closing this
report, although you should feel free to comment with any further questions.

Hello,

I just wanted to report a bug i think i hava found on the echo comand.

If you execute echo "!!!!!!!!!!!!!!!!!!!!!!!!" it does something strange
repeating the last command before echo comand.

I am using Ubuntu 14.04
