.SH "HOSTRANGED SUPPORT"
Multiple hosts can be input either as an explicit comma separated
lists of hosts or a range of hostnames in the general form:
prefix[n-m,l-k,...], where n < m and l < k, etc. The later form
should not be confused with regular expression character classes (also
denoted by ). For example, foo does not represent foo1 or foo9,
but rather represents a degenerate range: foo19.
This range syntax is meant only as a convenience on clusters with a
prefixNN naming convention and specification of ranges should not be
considered necessary -- the list foo1,foo9 could be specified as such,
or by the range foo[1,9].
Some examples of range usage follow:
foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
foo[7,9-10] instead of foo7,foo9,foo10
foo[0-3] instead of foo0,foo1,foo2,foo3
As a reminder to the reader, some shells will interpret brackets ([
and ]) for pattern matching. Depending on your shell, it may be
necessary to enclose ranged lists within quotes.
