SYNOPSIS

clustersed clusterfile | - string1 ... stringn

DESCRIPTION

The clustersed program is used to cut individual groups out of a cluster file. This can be used to see the contents of a particular group easily, or to generate special-use clusters on the fly. The results of the program will be sent to standard output. The following options are available:
clusterfile
  The first argument must either be the name of a cluster file, or a single dash ('-'). If the dash is given, the clusterfile will be read from the file indicated in the CLUSTER environment variable. If the CLUSTER environment variable does not exist, clustersed will process standard input.
string The second argument is a space separated list of one or more strings to search for in the cluster file. These are the names of groups within the cluster, and will only match group names. If a group name is matched, all nodes in that group will be printed out, along with the 'GROUP:' heading and the name of the group. You can partially match the begining of a group name with a string. For example, the argument 'serv' would match 'server1' and 'server2' but would not match 'subserv'.

ENVIRONMENT

clustersed utilizes the following environment variables:
CLUSTER
  Contains a filename, which is a newline separated list of nodes in the cluster.

DIAGNOSTICS

Exit status is 0 on success, 1 if an error occurs.
