hss is an interactive ssh client for multiple servers. It will provide almost the same experience as in the bash environment. It supports:

• interactive input: based on libreadline.
• history: responding to the C-r key.
• auto-completion: completion from remote server on the tab key, for commands and paths.

Command is executed on all servers in parallel. Execution on one server does not need to wait for that on another server to finish before starting. So we can run a command on hundreds of servers at the same time.

Usage: hss [-f hostfile] [-o file] [-u username] [command]...

Options:
  -f file        file with the list of hosts
  -H host        specifies a host option, support the same options as the ssh command
  -l limit       number of multiple ssh to perform at a time (default: unlimited)
  -u user        the default user name to use when connecting to the remote server
  -c opts        specify the common ssh options (i.e. '-p 22 -i identity_file')
  -o file        write remote command output to a file
  -i             force use a vi-style line editing interface
  -v             be more verbose
  -V             show program version
  -h             display this message

The fundamental of hss is to execute the ssh command for every host, and then show the results on the terminal. So hss supports every argument supported by the ssh command. Following is an example of the hostfile:

192.168.1.1
-p 2222 [email protected]
-p 2222 -i ~/.ssh/identity_file [email protected]
-p 2222 -oConnectTimeout=3 [email protected]

Connect to servers:

# Specify the hostfile directly
hss -f hostfile

# Or pass servers in arguments
hss -H '192.168.1.1' -H '-p 2222 [email protected]' -H '-p 2222 -i ~/.ssh/identity_file [email protected]' -H '-p 2222 -oConnectTimeout=3 [email protected]'

Passthrough of ssh arguments are supported. For example, by specify -c '-oConnectTimeout=3', sessions without a timeout configured will set its timeout on this argument.

The interactive input is implemented on libreadline, supporting command and path completion from remote, history storage and searching, moving around, etc. (please refer to readline for more)

• Command history is stored in file ~/.hss_history.
• Completion of commands and paths are based on the first server in the list.
• Path completion is available when the first input character is /, ~ or ..

• Solve the "@" suffix problem on directory symbol-link.
