GoSSH
Gossh is a high-performance and high-concurrency ssh tool. This tool can efficiently manage tens of thousands of Linux server clusters. It can efficiently execute commands, execute script file, transfer file, etc.
Features
-
Supports three types of ssh tasks.
exec
: Execute commands in remote hosts.script
: Execute a local script in remote hosts.push
: Push a local file to remote hosts. -
Supports using sudo to execute the commands or a script as other user(default is
root
). -
Supports specifying i18n environment variable value while executing commands or a script to help keep the language of the outputs consistent. For example:
zh_CN.UTF-8
,en_US.UTF-8
. -
Supports four authentication methods.
Priority:ssh-agent authentication
->pubkey authentication
->password from command flag
->username:password from a file
.
If the user is not specified, the system environment variable$USER
will be used by default. -
Supports two methods to specify target hosts. One is through command line arguments, input one or more target hosts, separated by space. The other is through command line flag or configuration file option to specify the hosts file. Both methods can be used at the same time.
-
Supports three kinds of timeout:
Timeout for connecting each remote host (default10
seconds).
Timeout for executing commands or a script on each remote host.
Timeout for the current gossh task. -
Supports printing the execution results of
gossh
to a file or screen or to a file and screen at the same time. Supports json format output. Supports printing debug information. Supports silent output. -
High-performance and high-concurrency. You can specify number of concurrent connections (default
1
). -
For ease of use, it supports config file. You can write flags that are not frequently modified into the config file, so you don't need to laboriously specify these flags on the command line. If the flag in both command line and config file, flag that from command line takes precedence over the other. The default config file is:
~/.gossh.yaml
. -
Provide the subcommand
config
to help users generate configuration file in easy way.
Installation
Prebuilt binaries for macOS and Linux can be downloaded from the GitHub releases page.
Also you can install gossh
by compiling:
$ git clone --depth 1 https://github.com/windvalley/gossh $ cd gossh # Note: need to install Go environment first. $ make && make install
Usage
$ gossh -h Gossh is a high-performance and high-concurrency ssh tool. This tool can efficiently manage tens of thousands of Linux server clusters.
