vector-utils is a collection of scripts for managing large numbers of similar machines over an ssh connection. It includes the following:

It has one configuration file, either /etc/vector.conf or /usr/local/etc/vector.conf, depending on whether it was installed from a package or a tarball. This currently has one parameter, a list of hostnames that the tools should operate on. It is recommended not to include the local machine in this list.

vector itself can be thought of as a lightweight, command-line alternative to clusterssh - but clusterssh does not include a scatter-gather function.




if [[ -z $MACHINES ]];
  MACHINES=myhost1 myhost2 otherhost1.otherdomain

It is recommended to use the -z construction, so that the list of machines can be overridden on the command line.

$ scatter file1 file2
$ gather file1 file2 
# local directory now contains: file1,host1 file2,host1 file1,host2 file2,host2 ...
$ vector "apt-get update && apt-get upgrade"
$ MACHINES="" vector hostname
