Handy tcsh aliases for use with chef knife shell
Here are some handy tcsh aliases for the knife shell utility of the opscode chef infrastructure automation solution:
alias knifeshell knife ssh "\!:1" interactive -a hostname -x YourUserName
This will connect to all servers matching a search query so:
knifeshell "hostname:a*" will connect to all servers with a hostname starting with the letter “a”
knifescreen knife ssh "\!:1" screen -a hostname -x -x YourUserName
This will do more or less the same as the previous command but it will use the gnu screen utility
and finaly:
alias kniferun knife ssh "\!:1" "\!:2" -a hostname -x YourUserName
will run a shell command on all servers matching the search query.
example:
to show the directory listing of your home folders for all servers known by chef:
kniferun "hostname:[* TO *]" ls
