Question

我写了run.sh。以下简称“java”类:

java -cp . Main $1 $2 $3 $4

这里是我的java阶级(它只是展示一种动力):

public class Main {
    public static void main(String[] args) {
        for (String arg : args) {
            System.out.println(arg);
        }
    }
}

除非我试图通过一个含有空间的参数,否则这项工作正在进行之中。例如:

./run.sh This is "a test"

显示:

This
is
a
test

How could I modify my shell script and/or change my parameter syntax to pass the parameter "a test" unmodified ?

Answer 1

与此类似:

java -cp . Main "$@"

Answer 2

您还必须在文字上掩盖每个参数:

java -cp . Main "$1" "$2" "$3" "$4"

现在,第4项参数应当是空洞的,3项应当是“测试”。

2. 核实和审判:

#!/bin/bash
echo 1 "$1"
echo 2 "$2"
echo 3 "$3"
echo 4 "$4"
echo all "$@"

页: 1

./params.sh This is "a test" 
1 This
2 is
3 a test
4 
all This is a test
