批处理文件提示使用管道中的空间

Question

I am using firebase as my host. When I upload my webpage I need to call two cmd instructions:

1. firebase init
2. firebase deploy

When I run firebase init I must answer some questions to go on. To the first question I enter y for yes and the second I need to enter space to deselect one item and then enter to go on.

I am trying to use a batch file for this instructions.

I found out that I can use a pipe with following content in a batch file, the file looks like this:

echo y | firebase init

but this "echo y" is only the first instruction for firebase init. After that I need to deselect one item with "space" and than "enter".

How can I write:

(echo y
echo "space"
echo "enter") | firebase init

Answer 1

First the firebase.json file must be created with echo in the right directory. This replaces the firebase init command.

Then run: firebase deploy -P project alias.

In bash it looks like:

echo $'{ "database": { "rules": "database.rules.json" }, "hosting": { "public": "public", "rewrites": [ { "source": "**", "destination": "/index.html" } ] } }\\n' >firebase.json

firebase deploy -P Test_Google_Analytics

Answer 2

Try it with

(
 (echo(y) 
 (echo( )
 (echo()
) | firebase init

This sends through the pipe

y<Linefeed>
<space><Linefeed>
<Linefeed>

The parenthesis seems to be unbalanced, but it's correct this way as echo( ensures that the content will be printed as is.

Should this work for you?

@echo off

:: start command
firebase init

:: wait command to load. IP must be unreachable for -w to work as expected
ping 1.1.1.1 -n 1 -w 500 >NUL

call:sendKeys

exit/B

:: spawn a cscript to echo desired keys to the same cmd window
:: sleep time may need to be changed
:sendKeys
SetLocal 
set "_vbs_file_=%TEMP%\keys.vbs"
(
  echo(set oWS ^= CreateObject^("wScript.Shell"^)
  echo(wScript.Sleep 100
  echo(oWS.SendKeys "y"
  echo(wScript.Sleep 100
  echo(oWS.SendKeys " "
  echo(wScript.Sleep 100
  echo(oWS.SendKeys "{ENTER}"
)>"%_vbs_file_%"
if exist "%TEMP%\keys.vbs" (set "_spawn_=%TEMP%\keys.vbs") else (set "_spawn_=keys.vbs")
ping 1.1.1.1 -n 1 -w 50 >NUL
start /B /WAIT cmd /C "cls & "%_spawn_%" & del /F /Q "%_spawn_%" 2>NUL"
exit/B 0

Edit: as echo sends an explicit carriage return, the sendkeys may be (also ping delay is now 1500 miliseconds)

@echo off

:: start command
firebase init

:: wait command to load. IP must be unreachable for -w to work as expected
ping 1.1.1.1 -n 1 -w 1500 >NUL

  echo(wScript.Sleep 100
  echo(oWS.SendKeys "y"
  echo(wScript.Sleep 100

  echo(oWS.SendKeys " "
