Check_http -u ..!.. Problem


I am trying to check a URL.
Here is what the problem is. The URL has an exclamation mark (!) and the command check_http is not working properly.

/usr/local/nagios/libexec/check_http -I xx.xx.xx.xx
-u “aaaaaaaaaaa=Hi!+abcaaaaaaaaa”
-f follow
-s “0 - Success”

When I run this in command line, I get
-bash: !+abcaaaaaaaaa: event not found

The question is how to make check_http to recognize the exclamation mark in the URL as part of the URL.
