NAME

sshdo --- Execute remote commands or copies via SSH to multiple hosts.  

SYNOPSIS

sshdo [ -h | --help ] [ -v | --version ] [ -m | --man ] [ -mm | --mman ] [ -f | --force ] -u username [ [ -g | -p ] from to [ -s suffix ] ] [ 'remote command' ]  

DESCRIPTION

sshdo issues remote commands, puts or gets files to all hosts sequentially. Hosts are read from stdin (one per line). sshdo will use SSH key agent, if available, to avoid repetitive password entry.

WARNING: Be sure to validate your command before issuing it. One mistake duplicated across multiple hosts could be catastrophic. Backups are also recommended.
