The ! is a special character in bash in some circumstances. The "" can
give it the special meaning.
>From my documentation on bash, !n references a previous command (the
nth command), it also allows use of characters to list previously
issued (history) commands that start with that character(s)
an example of the first use
[jeff@eye_gore ~]$ echo !12
echo mkdir temp2
mkdir temp2
and the second
[jeff@eye_gore ~]$ echo !n
echo ncftp 192.168.2.10
ncftp 192.168.2.10
So in that context the "!" structure forces it to be interpreted with a
null argument and thus not a valid event to be referenced.
[jeff@eye_gore ~]$ echo "!"
bash: !: event not found
is in a slightly different category though
