我正在尝试编写一个不使用任何文件输入参数或任何东西的简单awk脚本。到目前为止，我只测试过编写一个hello world程序：
let spyDelegate = SpyDelegate()
var asyncExpectation = expectation(description: "firstExpectation")
spyDelegate.asyncExpectation = asyncExpectation
let testee = MyClassToTest(delegate: spyDelegate)
testee.myFunction() //asyncExpectation.fulfill() happens here, implemented in SpyDelegate
waitForExpectations(timeout: 30.0) { (error: Error?) in
if let error = error {
XCTFail("error: \(error)")
}
}
asyncExpectation = expectation(description: "secoundExpectation")
spyDelegate.asyncExpectation = asyncExpectation
testee.delegate = spyDelegate
testee.myOtherFunction() //asyncExpectation.fulfill() happens here, implemented in SpyDelegate
waitForExpectations(timeout: 30.0) { (error: Error?) in
if let error = error {
XCTFail("error: \(error)")
}
}
当我尝试使用以下命令通过终端运行时出现错误#!/usr/bin/awk
BEGIN{}
{print "hello"}
END{}
：awk: 1: unexpected character '.'
为什么会这样？
谢谢

添加到shebang行的末尾，告诉-f脚本如下：
awk此外，由于您没有输入，请将#!/usr/bin/awk -f
放在print块内：
