| =head1 NAME |
| |
| B<pbsnodes> - display and manipulate host information in a PBS-like format |
| |
| =head1 SYNOPSIS |
| |
| B<pbsnodes> [B<-a>] [I<node_id>...] |
| |
| B<pbsnodes> B<-l> [B<-n>] |
| |
| B<pbsnodes> B<-{c|r|o}> [I<node_id>...] [ B<-N> "note/reason string"] |
| |
| =head1 DESCRIPTION |
| |
| The B<pbsnodes> command displays and manipulates information about |
| nodes. |
| |
| =head1 OPTIONS |
| |
| =over 4 |
| |
| =item B<-a> |
| |
| Display information for all nodes. This is the default if no node name |
| is specified. |
| |
| =item B<-c> |
| |
| Clear OFFLINE from listed nodes. |
| |
| =item B<-l> |
| |
| List node names and their state for nodes that are DOWN, OFFLINE, or |
| UNKNOWN. |
| |
| =item B<-N> |
| |
| Specify a "note/reason" attribute. Use "" to clear field. |
| |
| =item B<-n> |
| |
| Show the "note/reason" attribute for nodes that are DOWN, OFFLINE, or |
| UNKNOWN. This option requires B<-l>. |
| |
| =item B<-r> |
| |
| Reset the listed nodes by clearing OFFLINE. Functionally equivalent |
| to B<-c>. |
| |
| =item B<-? | --help> |
| |
| brief help message |
