We had need for something like that here. You're welcome to use all or part of what I cobbled up, called "sudo-hosts". Under GPL. See below.
Notable feature: allows commands to run in parallel, with output lines prepended by the appropriate hostname. I always have an ssh key registered with my ssh agent that allows password-free execution as root. Otherwise this stuff would be a serious hassle, and parallel mode wouldn't really work at all. Another option to consider (I wish someone would package it!) is cssh, with the accompanying xfanout, fanout, etc. It pops up a whole bunch of little xterms, each on a different host, and there's an extra little control window that sends stuff you type to *all* the little created xterms. Or a subset which can be changed by clicking on some little radio buttons. See http://www.bitmover.com/bitcluster/ for all the sources. It's a little rough around the edges, but a really good idea and it works well enough for routine use. --Barak. ---------------------------------------------------------------- #!/bin/sh # CVS version control block - do not edit manually # $RCSfile: sudo-hosts,v $ # $Revision: 1.9 $ # $Date: 2001/05/15 22:56:19 $ # $Source: /home/cvs/meg/system/sudo-hosts,v $ function usage() { PROG=`basename $0` echo "Usage: $PROG [options] command" echo echo "Description: Run given command on a bunch of hosts." echo echo "options:" echo " -h print this help text and exit" echo " -u user log in as user (default: $user)" (echo " -r hostlist list of remote hosts (default:"; echo " \"$hosts\")")|fmt -c echo " -p operate in parallel (background each command)" } function docmd () { h=$2 echo Host: $h if [ $parallel != 0 ]; then ssh -n -a -x -l $1 $2 $3 2>&1 | sed "s/^/$h: /" & else ssh -a -x -l $1 $2 $3 fi } hosts="dandruff phlegm dribble hangnail pus earwax clipping tears toejam loogie flake blood" offline="" user=root parallel=0 while getopts "hr:u:p" opt do case "$opt" in h) usage; exit 0 ;; u) user="$OPTARG" ;; r) hosts="$OPTARG" ;; p) parallel=1 ;; *) usage; exit 2 ;; esac done shift $((OPTIND - 1)) command="$*" echo Doing "$command" for h in $hosts; do docmd "$user" $h "$command" done if [ $parallel != 0 ]; then wait fi
