For each input line it parses the first -column, separated by a blank space, as a value and the remainder -of the line as a key. If the line does not contain a blank -space and entire line is parsed as a value and the key is an -empty string. If the line however contains a blank space it is -included in the key, thus a line contain only a value and a line -contain a value followed by a blank space is not interpreted has -having the same key. @command{median} outputs the median value -for each key. In @command{median}'s current implementation the -keys will be sorted in the output. Keys do not have to be sorted -or groups. @command{median} will do its best to print the median -of in the same format as the input values. The input for a group -is of even number and is numerical the mean value of the two -middle values is used, otherwise the lower of the two middle -values is is used. Of course, if the number of values is odd, -the middle value is always used and it does not matter whether -the input is numerical or not. - - - -@node Invoking -@chapter Invoking - -@command{median} is command line filter that does not take any -arguments.
