A trivial class for representing a subset of servers. It is used internally for restricting operations to a subset of all defined servers.
subsession = session.with(:app) subsession.exec("hostname")
Returns a new subsession that consists of only the first server in the server list of the current subsession. This is just convenience for slice(0):
s1 = subsession.first
# File lib/net/ssh/multi/subsession.rb, line 43 def first slice(0) end
Works as Array#slice, but returns a new subsession consisting of the given slice of servers in this subsession. The new subsession will have the same master session as this subsession does.
s1 = subsession.slice(0) s2 = subsession.slice(3, -1) s3 = subsession.slice(1..4)
# File lib/net/ssh/multi/subsession.rb, line 34 def slice(*args) Subsession.new(master, Array(servers.slice(*args))) end
