In bash (turning off interactive_comments):
$ shopt -u interactive_comments
$ echo hello # world
hello # world
$ # oh
bash: #: command not found
In zsh (by default):
$ echo hello # world
hello # world
$ # oh
zsh: command not found: #
zsh is the fun one though (allows setting the comment character):
$ histchars[3]='@'
$ echo hello @ world
hello @ world
$ setopt INTERACTIVE_COMMENTS
$ echo hello @ world
hello
$ @ oh, a comment
$
