Whenever I execute a command in tmux, for example, set status, the status bar turns yellow and echoes back the results of the command. I find this behavior rather obtrusive. Can I turn this behavior off?

You can set the quiet server option to suppress many of the messages that are displayed in the status line (including the message shown by set-option). This will not suppress messages that come from using the display-message command.

If the quiet option is too broad*, or you want to be able to review the messages with show-messages, then you might try setting the display-time session option to a very small value. This will affect all messages (even those from display-message), so it also may not be appropriate for all situations.

If you are only interested in suppressing the message from that one set status command/binding, and you are comfortable building software from source, then you might want to try out the current SVN trunk. Its set-option command has a -q option that suppresses the normal informational message (i.e. set -q status). This will be included in the next release (i.e. 1.7).

*quiet is is a server option, so it will affect all your sessions.
quiet prevents the message from being entered into the show-message message log. By default, (prefix) ~ is bound to show-messages.
display-time must be from the range 1–750. So zero is not a valid value, but the minimum value (1 millisecond) will probably be too fast to notice in most circumstances (e.g. unless your tmux server is on the other side of a slow link).
