How to run the next command automatically in batch file?

Question

I'm developing an angular-android application, so I have to run some commands in the cmd. My system has minimal specifications since the commands take some time to run, I have to keep on monitoring it. To reduce the time and concentrate on my other things I put some command in the batch file. For example

ng build
cordova clean browser
cordova build browser 
cordova run browser

I put the above commands and save it as a batch file. When I run this file it only executes first command ng build, it doesn't automatically jump to second line. Previously I used mac, in that I save these as .sh file and when I execute them, all the command inside that executed successfully. What should I do to execute next commands automatically in the batch file? Thank you.

I think the first command failed... – dan1st Feb 05 '20 at 12:18 — dan1st, Feb 05 '20 at 12:18
No, It was executed successfully. – e.k Feb 06 '20 at 10:07 — e.k, Feb 06 '20 at 10:07

Some like this:

@echo off && setlocal enabledelayedexpansion

call ng &&^
call cordova clean browser &&^
call cordova build browser &&^
call cordova run browser 
endlocal && goto :EOF

rem :: or in one line ::

call ng && (call cordova clean browser && (call cordova build browser &&(call cordova run browser)))

Or ...

@echo off && setlocal enabledelayedexpansion

set "_run=ok"
call ng && for %%i in ("clean browser","build browser","run browser
)do if "!_run!" == "ok" call cordova %%~i || set "_run="
endlocal && goto :EOF

In bat/cmd you can use the &, |, && and || operator, also combine them...

commandA &  commandB                    Run commandA and then run commandB
commandA && commandB                    Run commandA, if it succeeds then run commandB
commandA || commandB                    Run commandA, if it fails then run commandB
commandA && commandB || commandC        If commandA succeeds run commandB, if it fails commandC

Even if it works, it's dangerous, because if `ng` and `cordova` are batch files, then they implicitly exit the batch-file context to command-line context. That leads into strange side effects – jeb Feb 05 '20 at 12:35
@jeb, i've not know this is bat files.. know i understand the call suggetion – Io-oI Feb 05 '20 at 12:36
You'd need [delayed expansion](https://stackoverflow.com/questions/30282784/variables-are-not-behaving-as-expected/30284028#30284028) to make it work as intended or avoid it by using `if defined _run` – Stephan Feb 05 '20 at 14:33
@Stephan Danke schön! – Io-oI Feb 05 '20 at 14:50

add start before each of those commands

  start ng build 
  start cordova clean browser 
  start cordova build browser  
  start cordova run browser

It executes all the command at the same time. I want to execute second command, after the first command executed successfully. – e.k Feb 05 '20 at 09:26
Oops. Missed that one. – Sara Feb 05 '20 at 09:32
