Question

我有一个文件，其中每行包含一个shell脚本，如下所示

sh xyz.sh arg1 arg2
sh abc.sh arg1
sh klm.sh arg1 arg2 arg3

我希望每个命令都在一个单独的屏幕中执行，有没有一种简单的方法来执行此操作而不是通过命令创建屏幕

screen -S screen1
screen -S screen2
screen -S screen3

并从相应屏幕中的文件执行每个命令

使用bash：

import React, { Component } from 'react';
import {
  Platform,
  StyleSheet,
  Text,
  View
} from 'react-native';
import MapView from 'react-native-maps';

const styles = StyleSheet.create({
  container: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
  },
});

const instructions = Platform.select({
  ios: 'Press Cmd+R to reload,\n' +
    'Cmd+D or shake for dev menu',
  android: 'Double tap R on your keyboard to reload,\n' +
    'Shake or press menu button for dev menu',
});

class App extends Component {

  constructor(props) {
    super(props);
    this.state = {
      latitude: 0,
      longitude: 0,
      error: null,
      markers: []
    };
  }

  componentDidMount() {

     navigator.geolocation.getCurrentPosition(
      (position) => {

        fetch(API_URL)
           .then((response) => response.json())
           .then((responseJson) => {
              var relevantLocations = []
              for (var i = 0; i < responseJson.length; i++) {
                var location = responseJson[i];
                relevantLocations.push({
                  title: location.name,
                  coordinate: {latitude: location.latitude, longitude: 
                    location.longitude},
                  description: "test" + i
                });
              }
             console.log("Setting state");
             this.setState({
                ...this.state
                latitude: position.coords.latitude,
                longitude: position.coords.longitude,
                markers: relevantLocations
             });
           })
           .catch((error) => {
             console.error(error);
           });

       },
      (error) => this.setState({ ...this.state, error: error.message }),
        { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 },
      );


  }

  onRegionChange = (region) => {
    this.setState({ region });
  }

  onPress = () => {
  }

  render() {
    console.log(this.state.markers);
    return (
      <View style={styles.container}>
        <MapView style={styles.map}
          onRegionChange={this.onRegionChange}
          onPress={this.onPress}
        >
        {this.state.markers.map(marker => {
            return <MapView.Marker
              key={marker}
              coordinate={marker.coordinate}
              title={marker.title}
              description={marker.description}
            />
          })}
        </MapView>
      </View>
    );
  }
}

export default App;

打开多个屏幕以获取命令列表
