Execute binaries or shell scripts on multiple servers over ssh, implemented in bash only.
You can define servers in different files in folder 'groups'. A group can be defined using '-g' when starting multi-ssh.sh For example customer1, customer2 or squeezy, rehl6.
Use -g all to run the command or script on all servers.
-n|--dry-run don't run any command, only show them
-s|--silent don't show servernames
-c|--cron show servername only on remote output
-i|--stdin use stdin, even if CMD is not empty
Run command uptime on all servers.
multi-ssh.sh -g all uptime
example output:
