If the given \fIid\fR is a channel ID (64 hex digits as a string, or the short channel ID \fIblockheight:txindex:outindex\fR form), then it applies to that channel\&. .sp If \fIunilateraltimeout\fR is not zero, the \fBclose\fR command will unilaterally close the channel when that number of seconds is reached\&. If \fIunilateraltimeout\fR is zero, then the \fBclose\fR command will wait indefinitely until the peer is online and can negotiate a mutual close\&. The default is 2 days (172800 seconds)\&. .sp The peer needs to be live and connected in order to negotiate a mutual close\&. The default of unilaterally closing after 48 hours is usually a reasonable indication that you can no longer contact the peer\&. .SH "NOTES" .sp Prior to 0\&.7\&.2, \fBclose\fR took two parameters: \fIforce\fR and \fItimeout\fR\&. \fItimeout\fR was the number of seconds before \fIforce\fR took effect (default, 30), and \fIforce\fR determined whether the result was a unilateral close or an RPC error (default)\&. Even after the timeout, the channel would be closed if the peer reconnected\&. .SH "RETURN VALUE" .sp On success, an object with fields \fItx\fR and \fItxid\fR containing the closing transaction are returned\&. It will also have a field \fItype\fR which is either the JSON string \fImutual\fR or the JSON string \fIunilateral\fR\&. A \fImutual\fR close means that we could negotiate a close with the peer, while a \fIunilateral\fR close means that the \fIforce\fR flag was set and we had to close the channel without waiting for the counterparty\&. .sp A unilateral close may still occur at any time if the peer did not behave correctly during the close negotiation\&. .sp Unilateral closes will return your funds after a delay\&. The delay will vary based on the peer \fIto_self_delay\fR setting, not your own setting\&. .SH "AUTHOR" .sp ZmnSCPxj is mainly responsible\&. .SH "SEE ALSO" .sp lightning\-disconnect(7), lightning\-fundchannel(7) .SH "RESOURCES" .sp Main web site: https://github\&.com/ElementsProject/lightning
