如何使用 powershell 从批处理脚本中运行批处理脚本？

Question

How do I call another batch script from within a batch script in powershell. In bash I used to get this done using the CALL keyword. Is there an equivalent term for that in powershell??

My problem is basically to start a dev environment using a batch file and then run some commands in that environment with the second batch file.

I tried using something like

& Path\to\my\batchfile.bat -/c'command with spaces'

I was expecting it to open the dev environment with the batch file and run the provided command but it just keep runs the batch file and does not run the commands in it.

I'm assuming that your use case is as follows:

• You want to run batch file B.bat ,
• but batch file A.bat must run first , to set the environment that B.bat relies on.

# "foo" and "bar" are sample arguments for B.bat
cmd /c 'c:\path\to\A.bat && c:\path\to\B.bat foo bar'

Note:

• The call batch-file command is not needed in this case; call is only needed inside a batch file to call another batch file in a manner that returns control to the calling batch file.

• As long as A.bat sets its variables without using setlocal , B.bat will see those (environment) variables too. ^[1]

If A.bat does use setlocal - which limits the scope of variable definitions to that batch file ^[1] - and you're unable to modify A.bat to remove this constraint, there is no solution to your problem - irrespective of whether you call from cmd.exe or PowerShell. (That is, unless A.bat happens to be designed to accept a command line to execute as an argument .)

^{[1] Unlike in PowerShell, in cmd.exe all variables are environment variables. However, the optional setlocal command allows you to scope such variables to a given batch file (and, when paired with endlocal calls, even to parts of a batch file). For help, run setlocal /? and endlocal /? from cmd.exe .}
