Sort the function list on metric-spec. The visibility in the metric name does not affect the sort order. If more than one metric is named in the metric-spec, use the first one that is visible. If none of the metrics named are visible, ignore the command. You can precede the metric-spec with a minus sign (-) to specify a reverse sort.
By default, the metric sort setting is based on the dsort command processed from .er.rc files, as described in Setting Defaults in .er.rc Files. If a sort command explicitly sets metric_spec to default, the default settings are used.
The string metric-spec is one of the metric keywords described in Metric Lists, as shown in this example.
sort i.user
This command tells the er_print utility to sort the function list by inclusive user CPU time. If the metric is not in the experiments that have been loaded, a warning is printed and the command is ignored. When the command is finished, the sort metric is printed.
