NAME
median - Calculate the median values for a set of groups
SYNOPSIS
median < INPUT
DESCRIPTION
median takes the first blank space-separated column values
and the remainder as keys. It will then print the median for
each key. As a side effect median will print the result
sorted by the keys.
EXAMPLES
$ cat <<EOF | median
-10
2
4
3
50
EOF
3
$ cat <<EOF | median
+003 c
.001 a
-002 b
+001 c
-001 b
+002 c
EOF
.001 a
-001.5 b
+002 c
RATIONALE
Combining sort(1), sed(1), wc(1), expr(1) to do this is
too much work to do on a regular basis.
