Next time you want to say $ echo "This is fun!" What you probably want is
$ echo 'This is fun!' or even $ echo this is fun\! That's because double-quotes delimit a string, but they still allow the shell to expand the contents. The shell wants to replace a ! in plain-view with a history event. A single quote doesn't allow shell expansion.

Also, a side question: how come 'events' and exclamation marks cause havoc in bash, in seemingly innocent situations: $ echo "This is fun!" -bash: !": event not found cheers rickw -- _________________________________ Rick Welykochy || Praxis Services People who enjoy eating sausage and obey the law should not watch either being made. -- Otto von Bismarck -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
