節點每個Js文件只運行一個Exec（子進程） 有什麼方法可以在單個Js文件中運行多個exec命令？ 在異步系列函數exec執行命令後停止， 我如何使所有三個exec函數執行，而不是出來的項目？節點每個js文件運行一個exec
這是我曾嘗試：
var exec = require('child_process').exec;
var fs = require('fs');
var async = require('async');
var find = /regex/;
async.series({
one:function(callback){
exec('git ls-remote',{maxBuffer: 1024 * 500}, function(error, stdout, stderr) {
fs.writeFile(__dirname+'/idsandDates.txt',stdout, function (err) {
if (err) throw err;
//console.log(stdout);
});
console.log('stderr Here: ' + stderr);
if (error !== null) {
console.log('exec error Here: ' + error);
callback(null,1);
}
});
}
,
two:function(callback){
var LineByLineReader = require('line-by-line'),
lr = new LineByLineReader('idsandDates.txt');
var commitId;
lr.on('error', function (err) {
// 'err' contains error object
});
lr.on('line', function (line) {
if(line.search(find)>0){
commitId = line.split("\t")[0];
}
});
lr.on('end', function() {
console.log('hello');
exec('git show -s'+commitId,{maxBuffer: 1024 * 500}, function(error, stdout,stderr) {
fs.writeFile(__dirname+'/commitDateFile.txt',stdout, function (err) {
if (err) throw err;
console.log(stdout);
});
callback(null,2);
});
});
}
,
three:function(callback){
var find = /Date:/;
var LineByLineReader = require('line-by-line'),
lr = new LineByLineReader('commitDateFile.txt');
var commitDate;
var i = 1;
lr.on('error', function (err) {
// 'err' contains error object
});
lr.on('line', function (line) {
if(i==3){
commitDate= line.slice(5,line.length).trim();
}
i++;
});
lr.on('end', function(){
var date = new Date(commitDate);//--since='+trueDate+'--name-only --pretty=format:
var trueDate = date.getFullYear()+'-'+date.getMonth()+'-'+date.getDay();
console.log(trueDate);
var exec = require('child_process').exec;
exec('git log --since='+trueDate+' --name-only --pretty=format:',{maxBuffer: 1024 * 500}, function(error, stdout, stderr) {
fs.writeFile(__dirname+'/modiiedJs.txt',stdout, function (err) {
if (err) throw err;
console.log(stdout);
});
console.log('stderr her1: ' + stderr);
if (error !== null) {
console.log('exec error Here2: ' + error);
callback(null,3);
}
});
});
}
},
function(err, results) {
console.log(results);
}
);
