new command will not begin until the previous one is finished, i.e. these do not run in parallel.

Sending a SIGINT (usually a ^C) will cause the current host to be skipped, and sending a

SIGQUIT (usually a ^\) will immediately abort the whole clsh command.

Percent interpolation, as in clcp, is also supported.

clsh exits wth a non-zero status if there are problems running the remote shell commands. A

summary of hosts on which problems occurred is printed at the end.

clsh is used as follows:

clsh [-C cluster-group] [options] cmd [args]

Examples

To grep for something on all hosts in the cluster:

% clsh grep pattern files ...

To append something to a file on all machines:

% clsh -i "cat >> file" < addendum

To run a command with a five second timeout on all the hosts in the cluster group "hp",

directing output into separate files:

% clsh -o -t5 -C hp date

clsh -o -t5 hp date

A cluster name without a -C must follow all flag arguments.

For more details on the usage of clsh, invoke the command:

% man clsh

3.1.6 clcp - Copies files to one, some, or all cluster nodes.

clcp copies files between nodes in the cluster using rcp. Each file for directory argument is

either a remote file name of the form "%h:path", "cluster:path", or a local file name

(containing no ":" characters).

clcp can do the following types of copies:

1 2 ... 126 127 128 129 130 131 132 133 134 135 136 ... 172 173
