Mussh NPM | npm.io

MUlti SSH

For running SSH commands on multiple servers.

Usage

To run on all web servers:

mussh run -t role:web "ls -lah"

To run on a specific server:

mussh run -i app1 "ls -lah" "df -h"

To run a local script

mussh run -t role:web -s ~/scripts/test.sh

Matching

Target servers will be selected from the config file by either id(s) ot tag(s).

Specifying multipe --id <id> (or -i <id>) arguments will select the servers matching the specified ids.

Specifying multiple --tag <tag> (or -t <tag>) arguments will select only the servers that have all of the matching tags. (i.e. each tag argument filters down the number of target servers). E.g. to target all web servers in west-us you specify -t web -t west-us.
