只有在cmdline和linuxmode中才其作用，可以实现高亮
也可以通过文本来存放主机组和命令组，通过换行符分隔。
cmdfile
cd /etc/sysconfig/network-scripts/
ls
date
echodate
#!/bin/bash
#echo time
for((i=0;i<3;i++))
do
sleep 1
echo $(date +"%Y-%m-%d %H:%M:%S")
done不支持cmdfile,添加-b参数可以实现高亮
gosail login exec mode -?

-u, --username string host username对于 linux ，支持 linuxMode 模式，也就是将命令组合通过 && 连接后，使用 session.Run() 运行。
不显示主机名，只有返回结果。
输出可以打成 json 格式，方便程序处理。
可以通过输入id登录主机，并且显示主机是否可以登录的状态。
✋Server List:
Enter the 0~2 to select the host, other input will exit!
0 : 192.168.245.13 [x]
1 : 192.168.245.132 [√]
2 : 192.168.245.133 [√]
Input id :k8s pull 相同
pull时，可添加--tar参数将远端的文件压缩后，进行拉取。
从主机批量并发拉取文件到本地，本地文件支持相对路径以及其他主机目录（username@host:/path)，文件下每个主机的文件以各自主机名作为区分。
默认使用sftp方式进行传输

gosail is a free and open source batch and concurrent command execution system,
designed to execute commands on multiple servers or k8s pods and get results with speed and efficiency.
You can also copy(pull or push) files by it.
Commands:
=========
clear clear the screen
color Color for prompt
exec Exec can execute commands concurrently and in batches on all hosts and k8s pods, no args to exec mode
exit exit the shell
help use 'help [command]' for command help
login, select Login host to do something
mode Mode offers choices of exec output formats
pull, download Pull can copy file from hosts or pods, and create folders to distinguish
push, upload Pull can copy file to hosts concurrently, and create folders that do not exist
set Set the gosail config
show Show the hosts
Sub Commands:
=============
login:
k8s K8s master to do something, need login first通过gosail或者gosail --hostfile "<hostfile>" [-u "<username>"] [-p "<password">]进入交互界面
进入后通过login以及其参数加载宿主机的信息
设置 key\ciphers\keyexchanges\numlimit\timelimit等参数
显示hosts
批量在主机和k8s pod中执行命令，k8s支持通过-b高亮
直接通过exec可进入循环执行命令行模式
clear可以清理多余屏幕
Ctrl+C、exit或者quit可以退出
设置linuxmode\jsonmode\selection等参数
k8s的linuxmode为false
同命令行中的参数，k8s不支持push
gosail 0.17.0之后支持读取默认配置，在gosail同级目录下的gosail.conf，预配置的文件可以减少参数的指定

timeout_limit = 10
number_limit = 10
[spin]
# 0:Tips 1:Move 2:Bar (default is 0)
spin_type = 2
# spin_tips = "wait, gosail is in progress ..."
[login]

使用 gosail spinner : >))'>，可以通过在配置文件中指定提示方式
在等待时候进行提示。
