[英]How to pass a command as a command line argument by Batch file
I want to pass a command as a command line argument from one batch file to another. 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批处理文件。
eg : 例如:
first.bat: first.bat:
call test.bat "echo hello world" "echo welcome "
test.bat: test.bat的:
set initialcommand=%1
set maincommand=%2
%maincommand%
%initialcommand%
Here's what you need: 这就是你需要的:
first.cmd:
@echo off
set maincommand=echo hello world!
call test.cmd %maincommand%
test.cmd:
@echo off
%*
In this case first.cmd
passes the actual command (your example just passed the constant string "maincommand"
rather than its value). 在这种情况下,
first.cmd
传递实际命令(您的示例只传递常量字符串"maincommand"
而不是其值)。
In addition, test.cmd
executes a command made up of every parameter, not just the first. 另外,
test.cmd
执行由每个参数组成的命令,而不仅仅是第一个参数。
When you create those two files and execute first.cmd
, you get: 当您创建这两个文件并执行
first.cmd
,您会得到:
hello world!
as expected. 正如所料。
