> {{traffic_line}} is a handy tool to manage a traffic server instance. For example it is possible to retrieve and set configuration settings through command line like this:
> {code} 
> root@wv-tmp2:/home/at# traffic_line -r proxy.config.http.server_port ; echo $?
> 81
> 0
> {code} 
> However, some commans can be set, but aren't effective until the server is restarted, despite of ATS offering the _-x_ option to flush configuration and reread new settings:
> {code} 
> root@wv-tmp2:/home/at# traffic_line -s proxy.config.http.server_port -v 80 ; echo $?
> 0
> root@wv-tmp2:/home/at# traffic_line -x ; echo $?
> 0
> {code} 
> Trafficserver should possibly warn when setting such settings which aren't effective until the server is restarted and leave with a non-zero exit status for _-x_ in such cases. 
> Moreover {{traffic_line}} does not work at all if the manager is not running: 
> {code} 
> # traffic_line -r proxy.config.http.server_port ; echo $?
> traffic_line: Variable Not Found
> 1
> {code} 
> That's all right, but the error message shall be improved telling that. :)
