One of the biggest offenders I find is the exclamation point. For
example, try the following:
(note that the second one has two exclamation points). The result
replaces the "!!" with the previous command, so you end up with
Even more confoundingly, make it an interrobang:
echo "Hello!? I love this"
and it will hang waiting for a closing quote (even though you already
put one in) because the "!?" syntax attempts to replace the stuff
after the exclamation point with the most recent item in your
command-history that contained " I love this".
You can also have problems if you have a "$" in your text:
echo "It cost me $5"
which attempts to replace the "$5" with the (non-existent) 5th
argument to a function/script, so it outputs merely "It cost me "
Each of them involves consistent and understandable behavior, you
just have to know what to expect.
