#BSSH (🐝SSH)

Bulk SSH is a CLI for executing remote commands via SSH on multiple servers.

Usage: bssh [options] "<command to execute remotely>"

Options	Description
-V, --version	output the version number
-f, --file [filepath]	What file contains the SSH commands to run the command with?
-i, --identity [identity_file]	The path to your keypair file
-s, --synchronous	Just run everything and let results come back in live. More difficult to read results, but more efficient to run commands.
-u, --user [username]	The username you wish to use
-h, --help	output usage information

Example

In certain circumstances you just want to go directly to a specific docker instance (say to get to a shell within it)

Rather than:

• ssh -i somekey.key [e-mail]
• sudo docker service ls
• sudo docker service ps k28s53gd52fd
• exit
• ssh -i another.key [e-mail]
• sudo docker exec -it 781nd7s5g2s ash

Use BSSH

• bssh -f ./production-server-list -i somecommon.key -u ubuntu "sudo docker ps"
• ssh -i somecommon.key [e-mail]
• sudo docker exec -it 781nd7s5g2s ash

If you have an SSH config set up it is even simpler as you can cut out the key and user:

• bssh -f ./production-server-list "sudo docker ps"
• ssh -i somecommon.key [e-mail]
• sudo docker exec -it 781nd7s5g2s ash
