ssgo是一个基于SSH协议开发的小工具，面向系统管理员，主要用于在远程主机上执行命令、脚本或传输文件
go get github.com/JeffreySE/ssgo
--example获取该命令的使用案例192.168.100.2192.168.100.2-5 或 192.168.100.2-192.168.100.5 都是可以的192.168.100.0/28或192.168.100.0/255.255.255.240 都是可以的192.168.100.2,192.168.100.3-192.168.100.5,192.168.100.0/29 只要以英文逗号分隔开即可作为运维人员经常需要和远程主机（好吧 有时候是一大堆）打交道，执行脚本、执行命令、传输文件是三个最基本的诉求了，前期有接触过Ansible 使用已经很方便了，但是不够轻量；也使用Python基于paramiko库编写过小轮子，无奈有些虚机、系统上竟然没有预装paramiko组件，更可恨的是还要解决一堆依赖关系，对系统进行修改。。。
为了解决这些痛点，重新使用Go语言造了一个轮子 基本满足这些需求，初学Go语言，开发过程中学到了很多，当然啦，代码比较烂，请见谅

λ go run main.go
usage: ssgo [<flags>] <command> [<args> ...]
A SSH-based command line tool for operating remote hosts.
Flags:
-h, --help Show context-sensitive help (also try --help-long
and --help-man).
-e, --example Show examples of ssgo's command.
-i, --inventory=INVENTORY For advanced use case, you can specify a host
warehouse .ini file (Default is 'config.ini' file
in current directory.)
-g, --group=GROUP Remote host group name in the inventory file,
which must be used with '-i' or '--inventory'
argument!
--host-file=HOST-FILE A file contains remote host or host range IP
Address.(e.g. 'hosts.example.txt' in current
directory.)
--host-list=HOST-LIST Remote host or host range IP Address. e.g.
192.168.10.100,192.168.10.101-192.168.10.103,192.168.20.100/28,192.168.30.11-15
-p, --pass=PASS The SSH login password for remote hosts.
-u, --user="root" The SSH login user for remote hosts. default is
'root'
-P, --port=22 The SSH login port for remote hosts. default is
'22'
-n, --maxExecuteNum=20 Set Maximum concurrent count of hosts.
-o, --output=OUTPUT Output result'log to a file.(Be default if your
input is "log",ssgo will output logs like
"ssgo-%s.log")
-F, --format="simple" For pretty look in terminal,you can format the
result with table,simple,json or other
style.(Default is simple)
--json-raw By default, the json data will be formatted and
output by the console. You can specify the
--json-raw parameter to output raw json
data.(Default is false)
-w, --maxTableCellWidth=40 For pretty look,you can set the printed table's
max cell width in terminal.(Default is 40)
-v, --version Show application version.
Commands:
help [<command>...]
Show help.
list
List available remote hosts from your input.
run [<flags>]
Run commands on remote hosts.
copy --action=ACTION --src=SRC [<flags>]
Transfer files between local machine and remote hosts.
config.ini文件
# 2. ssgo tools use ini config file for advanced usage
# 3. Important Tips： you can't use 'all' as a host group name, cause 'all' will be identified as all host in your config.ini file.
