It sounds like you've got csh-style history expansion enabled, which should
not be the default behavior in a script. (It *is* the default in an
interactive shell.)
Try disabling it with "set +o histexpand".
If you're actually working with an interactive shell and don't want to
give up history expansion (even temporarily), you will just have to
figure out how to work around the quoting hell you're stuck in. Try
using single quotes instead of double quotes, or using $'...' quoting
with backslash-escaped inner single quotes, or whatever it takes.
I found it a lot easier just to:
imadev:~$ head -2 .bashrc
set -o vi
set +o histexpand
