在提示符下编写批处理Windows命令但不执行

Question

To avoid to repeat a task too often, I am setting up a batch file (in WINDOWS 10). It opens several CMD PROMPT to a specific Directory and launch a command.

For one case, I want the CMD PROMPT to open, to go to the specific directory and to set the COMMAND in the PROMPT without launching it. Then I'd just have to click on ENTER to launch that command whenever I want later on.

Here is my code:

setlocal ENABLEEXTENSIONS
set CordovaProjPath="C:\MyPath\"
start cmd /k "cd /d %CordovaProjPath% && cordova build android"

With this code it launches the command "cordova build android".

If I go with start cmd /k "cd /d %JCACordovaProjPath% instead of start cmd /k "cd /d %JCACordovaProjPath% && cordova build android" it gives me the PROMPT with: "C:\\MyPath>", I'd like to write: "cordova build android" behind it without launching the command.

Any idea?

Answer 1

Would something like this do you:

@Echo Off
Set "CordovaProjPath=C:\MyPath"
Set "CommandToRun=cordova build android"
Start "%CommandToRun%" Cmd /K "Cd /D %CordovaProjPath%&Echo %CommandToRun%&Pause>Nul&%CommandToRun%"

Below is an alternative which may allow for your alternative double-quoting method:

@Echo Off
Set CordovaProjPath="C:\MyPath"
Set CommandToRun="cordova build android"
Start %CommandToRun% Cmd /K "(Cd /D %CordovaProjPath%)&(Echo %CommandToRun%)&(Pause>Nul)&(%CommandToRun%)"

Answer 2

To provide repeatable execution (as mentioned in comments) you can put the relevant commands in a loop with a "quit" option:

@Echo Off
    setlocal
    Set "CordovaProjPath=C:\MyPath"
    Set "CommandToRun=cordova build android"
:loop
    Cd /D %CordovaProjPath%
    Echo %CommandToRun%
    set QUIT=
    set /p QUIT=Press ENTER to run command or 'Q' to quit:
    if /i "%QUIT%" == "Q" goto :eof
    %CommandToRun%
    goto :loop

Unlike the original, this runs the target command in the same command-window as the repeating loop. Depending on what the command in question does, this may be more attractive (less windows popping-up). However, some commands may cause the main window to close; if this is the case, you can revert to running the command in its own window in one of two different ways. In each case, replace the line:

    ...
    %CommandToRun%
    ...

Run in own window and remain open

    ...
    start "%CommandToRun%" /wait cmd /k %CommandToRun%
    ...

Using /k will leave the command-prompt window open after the target command has run -- this may be appropriate if you need to see the output of the command and it does not have its own pause.

Run in own window then close

    ...
    start "%CommandToRun%" /wait cmd /c %CommandToRun%
    ...

Using /c will mean the command-prompt will close after the target command has run. This may be appropriate if you do not need to see the output of the command, or if it has its own pause.
