如何通过批处理文件将命令作为命令行参数传递 [英] How to pass a command as a command line argument by Batch file

问题描述

我想将命令作为命令行参数从一个批处理文件传递到另一个.

I want to pass a command as a command line argument from one batch file to another.

例如:

first.bat:

first.bat:

call test.bat "echo hello world" "echo welcome "

test.bat:

set initialcommand=%1

set maincommand=%2

%maincommand%

%initialcommand%

推荐答案

这是您需要的:

first.cmd:

@echo off
set maincommand=echo hello world!
call test.cmd %maincommand%

test.cmd:

@echo off
%*

在这种情况下， first.cmd 传递实际命令(您的示例只是传递了常量字符串"maincommand" 而不是其值).

In this case first.cmd passes the actual command (your example just passed the constant string "maincommand" rather than its value).

此外， test.cmd 执行一个由每个参数组成的命令，而不仅仅是第一个.

In addition, test.cmd executes a command made up of every parameter, not just the first.

创建这两个文件并执行 first.cmd 时，您将得到:

When you create those two files and execute first.cmd, you get:

hello world!

符合预期.
