Substitute ResultVars

1. define result variables like ... => @varName
2. use the variables like echo @varName

Notice:

1. @varName which is not capitalized will be limited to the host related.
2. @VarName which is capitalized will be global to all hosts.

#printConfig = false
#passphrase="xxxx"

hosts = [
"12.26.85.62:1082 root/111",
"12.26.85.62:1083 root/222",
"12.26.85.62:1084 root/333",
]

# 全部命令都默认成远程执行，相当于自动添加了%host标识。
globalRemote = true
cmdTimeout = "15s"

cmds = [
    "date '+%Y%m%d' => @Today",
    "sh /tmp/hostdailycheck.sh",
