在以“declarations:”字符串开头的行的文本文件中，将“declarations”替换为“imports”，将“AppComponent”或“NxWelcomeComponent”替换为“”，解析结果字符串以获取用逗号“，”分隔的单个字符串，并从上面获取它们相关的导入字符串。例如：

import { RouterModule } from '@angular/router';
import { ScrollDirective } from './directives/scroll.directive';
import { TestComponent } from './test';
import { Test2 } from './test2';
import { Test3 } from './test';

@NgModule({
  declarations: [AppComponent, NxWelcomeComponent, ScrollDirective, TestComponent, Test2],
})

预期输出：

import { ScrollDirective } from './directives/scroll.directive';
import { TestComponent } from './test';
import { Test2 } from './test2';

imports: [ScrollDirective, TestComponent, Test2],

我试过了：test.awk：

/declarations:/ {str=$0;  sub("declarations", "imports", str) ; sub("AppComponent,", "", str) ; sub("NxWelcomeComponent,", "", str) }
/import/ { importbuf[++arrindex]=$0}

END {
    for (i in importbuf) {
        print importbuf[i]
    }
    print str
}

awk -f test.awk in

额外输入2：

import { RouterModule } from '@angular/router';
import { ScrollDirective } from './directives/scroll.directive';
import { TestComponent } from './test';
import {Test4} from './test4';

@NgModule({
  declarations: [AppComponent, NxWelcomeComponent, ScrollDirective, TestComponent, Test4],
})

预期结果2：

import { ScrollDirective } from './directives/scroll.directive';
import { TestComponent } from './test';
import {Test4} from './test4';

imports: [ScrollDirective, TestComponent, Test4],

awk -f test.awk in2

如何 grep 文本文件中 '' 内的第一个字符串？在：

path: '', redirectTo: '/login', pathMatch: 'full' },
path: 'login', component: LoginComponent },
path: 'registration',
path: 'employees',
path: 'recruitment',
path: 'work',

出去：

login
registration
employees
recruitment
work

我试过：

grep -Po "path: '\K.*'" in

如何使用这些规则从多行文本文件中提取多个字符串？搜索字符串为“String server”、“pac”和“String method”。它们在封闭的“{}”中可能只出现一次，也可能不出现一次。如果搜索字符串“String server”的值未包含在“”内，则忽略其值。搜索字符串匹配后，提取“”内不含“()”的值。搜索字符串“ pac ”的值优先于搜索字符串“String server”的值。搜索字符串“String server”或“pac”的值仅出现一次 - 不重复。它的值将出现在搜索字符串“String method”的值之前。例如示例文本文件位于：

{{{{{
public AResponse retrieveA(ARequest req){
    String server = "AAA";
    String method =  "retrieveA()";
    log.info(method,
            server,
            req);
    return res;
}

public BResponse retrieveB(BRequest req){
    String method =  "retrieveB()";
    BBB pac = new BBB();
    log.info(method,
            pac,
            req);
    return res;
}

public CResponse retrieveC(CRequest req) {
    String server = "CCC";
    log.info(server,
            req);
    return res;
}

public DResponse retrieveD(DRequest req) {
    String method = "retrieveD()";
    log.info(method,req);
    return res;
}

public EResponse retrieveE(ERequest req){
    EEE pac = new EEE();
    String method =  "retrieveE()";
    String server = "EEE";
    log.info(method,
            server,
            pac,
            req);
    return res;
}

public FResponse callretrieveF(FRequest req) throws InvalidDataException {
        String server = "FFFFF";
        //retrieveF
        String method =  "retrieveF()";
        try {
            log.info(method,
                     server,
                     req);

            FFFFF pac = new FFFFF();
        }
}

/**

public GResponse callgetG(GRequest req) throws InvalidDataException {
        //getG
        String method =  "getG()";
        String server = "GGGGGG";
        try {
            try {
                GGGGGG pac = new GGGGGG();
                log.info(method,

                     req);
            }
        }
}

/**

    public HResponse getH(HRequest req) 
                                throws InvalidDataException {

        //getH
        String method =  "getH()";
        String server = "HHHHHHH";
        String calledMethod =  "getH2()";

        ARequest aReq = new ARequest(req.getH(),
                                     req.getR());
        ProgramAccountInformationResponse resp = null;
        try {

        String method = "callI()";
        IIIII pac = new IIIII();
        String server = pac.getName();
    }
}}}}}

预期输出：

AAA retrieveA
BBB retrieveB
CCC 
    retrieveD
EEE retrieveE
FFFFF   retrieveF
GGGGGG  getG
HHHHHHH getH
    determineI
IIIII callI

从多行文本文件中提取多个字符串 - 较大的测试文件 无法正确获取最后 2 个输出的解决方案 ：确定I IIIIII callI
