esxi底層其實也是linux系統，可以使用shell指令碼進行一些操作，但是由於shell型別的問題，部分bash的指令碼無法執行，可以考慮使用python指令碼

[root@localhost:~] vmware -v
VMware ESXi 6.7.0 build-14320388
[root@localhost:~] cat /etc/shells
/bin/ash
/bin/sh
[root@localhost:~] python -V
Python 3.5.7

常用命令：

• esxicli：主要用來做一些系統及的操作，網路、磁碟、系統等操作，同時還有vm的一些操作

[root@localhost:~] esxcli
Usage: esxcli [options] {namespace}
 
+ {cmd} [cmd options]

Options:
  --formatter=FORMATTER
                        Override the formatter to use for a given command. Available formatter: xml, csv, keyvalue
  --debug               Enable debug or internal use options
  --version             Display version information for the script
  
 
-?, --help            Display usage information for the script
