是的，有。&。

如果命令1没有失败，&&将在命令1完成时执行命令2。

无论如何都会执行。

在windows中，我使用了上述所有解决方案&，&&，但都不起作用 ';'符号终于为我工作了

npm install; npm start

我尝试在同一个窗口中有两个ping，它是在同一行上的串行命令。完成第一个命令后，执行第二个命令。

解决方案是在Windows 7命令提示符中结合start /b。

像往常一样启动，不带/b，并在单独的窗口中启动。

在同一行中用于启动的命令是:

start /b command1 parameters & command2 parameters

无论如何，如果您希望解析输出，我不建议使用这种方法。 我注意到输出在命令的输出之间被打乱了。

你可以使用call来克服环境变量被太快求值的问题。

set A=Hello & call echo %A%

文档中的一段话:

Using multiple commands and conditional processing symbols You can run multiple commands from a single command line or script using conditional processing symbols. When you run multiple commands with conditional processing symbols, the commands to the right of the conditional processing symbol act based upon the results of the command to the left of the conditional processing symbol. For example, you might want to run a command only if the previous command fails. Or, you might want to run a command only if the previous command is successful. You can use the special characters listed in the following table to pass multiple commands. & [...] command1 & command2 Use to separate multiple commands on one command line. Cmd.exe runs the first command, and then the second command. && [...] command1 && command2 Use to run the command following && only if the command preceding the symbol is successful. Cmd.exe runs the first command, and then runs the second command only if the first command completed successfully. || [...] command1 || command2 Use to run the command following || only if the command preceding || fails. Cmd.exe runs the first command, and then runs the second command only if the first command did not complete successfully (receives an error code greater than zero). ( ) [...] (command1 & command2) Use to group or nest multiple commands. ; or , command1 parameter1;parameter2 Use to separate command parameters.

很简单:用&&符号区分它们。 例子:

echo "Hello World" && echo "GoodBye World".

“再见世界”将印在“你好世界”之后。
