最近在進行一個工作專案，需要在swift中呼叫shell指令碼：

Swift呼叫shell介面

• 1. GetQCRLog.swift

class GetQCRLog: NSObject{

    override init() {
        super
 
.init()
        searchAndDownLogsFromQCR()
        unzipDownFiles()
        foundContentFromFiles()
    }

    /** 從QCR上批量下載指定 SNs 的logs */
    func searchAndDownLogsFromQCR(){
        let scriptPath = homePath + "/getQCRLog"
        let snPath = homePath + "/sn.txt"
        let logPath = homePath + "/QCR_LOG"
 

        let logPartName:String = "123.zip"
        execShellScript(scriptPath, logPath, snPath, logPartName)
    }

    /** 解壓已下載的檔案 */
    func unzipDownFiles(){
        let scriptPath = homePath + "/unzipFiles"
        let logPath = homePath + "/QCR_LOG"
        execShellScript(scriptPath, logPath)
    }

    /** 批量查詢DCSD檔案中內容 “STATION_IP”，並將結果儲存在STATION_IP.txt */
 

    func foundContentFromFiles(){
        let scriptPath = homePath + "/foundContentFromFiles"
        let searchFileDir = homePath + "/QCR_LOG"
        let searchFileName = "DCSD.log"
        let searchContent = "STATION_IP"
        let resultFile = homePath + "STATION_IP.txt"
        execShellScript(scriptPath, searchFileDir, searchFileName, searchContent, resultFile)
    }
    /** Swift 呼叫任意引數個數Shell指令碼

     */
    func execShellScript(_ members: String...){
        var index = 0
        var scriptPath:String!
    //  var logPath:String!

        var args:Array = [String]()
        for i in members{
            if index == 0{ // 第一個引數是指令碼路徑
                scriptPath = i
                index += 1
                continue
            }
            args.append(i)
            index += 1
        }
        print(args)
        let task = Process()
        task.launchPath = scriptPath
        task.arguments = args
        let pipe = Pipe()
        task.standardOutput = pipe
        task.launch()

        let data = pipe.fileHandleForReading.readDataToEndOfFile()
        let output: String = String(data: data, encoding: String.Encoding.utf8)!

        print(output)
    }
}

被呼叫的指令碼工具

• unzipFiles.sh
  批量解壓指定目錄下的zip檔案

#!/bin/bash
if [ $# -ne 1 ] ; then
    echo "please input:./unzipFiles filedir"
    exit
fi

file_path="$1"     #加上雙引號才能支援檔案路徑中帶有空格的路徑名(/tmp/test 2/),使用./changefile.sh /tmp/test\ 2

if [ -d "$file_path" ] && cd "$file_path"
then
    for filename in `ls *.zip`
        do
                unzip -o  $filename -d ${file_path}/${filename%.*}    #解壓檔案
        done
fi
echo "finished---spend time:$SECONDS"      #顯示執行時間

• foundContentFromFiles.sh
  檢索 指定目錄 下 指定檔名 內容是否包含 關鍵字 ，並返回當前行內容

#!/bin/bash
if [$# -ne 4]
then
        echo "Usage:"
        echo "e.g. :./foundContentFromFiles searchFileDir searchFileName searchContent resultFile"
        exit
fi

searchFileDir = $1
searchFileName = $2
searchContent = $3
resultFile = $4
find $1 -iname $2 | xargs grep $3 >> $4

• getQCRLog.sh
  從伺服器批量下載log。這段程式碼有點亂，不具有通用性，有空再改。

#!/bin/bash
