To execute bash script from .bat file and .bat file is called by QT application
提问by samantha
I need help regarding executing bash script from batch scrip(.bat) which is called by Qt application inside Windows.
我需要有关从 Windows 内的 Qt 应用程序调用的批处理脚本（.bat）执行 bash 脚本的帮助。
Overview of a problem:I need to transfer files from Windows to Linux box via Qt application and run bash script inside linux to execute few commands.
问题概述：我需要通过 Qt 应用程序将文件从 Windows 传输到 Linux box，并在 linux 中运行 bash 脚本来执行一些命令。
What I have done so far :I can successfully transfer the files from windows to Linux box via Qt application. The Qt application calls the batch file which transfers the file
到目前为止我所做的：我可以通过 Qt 应用程序成功地将文件从 Windows 传输到 Linux 机器。Qt 应用程序调用传输文件的批处理文件
example
例子
void Qt_intro101::on_file_upgrade_clicked()
{
QFileInfo fileInfo( ui->selected_file->text() );
if( !fileInfo.exists() )
{
QMessageBox::information(this, tr("Information"),
tr("Unable to find file for upgrading!"));
return;
}
// copying update
QString fileName = fileInfo.absoluteFilePath();
//Check if cmd.exe is present in Clients system and is located at correct path
QFileInfo cmdFile( "C:\Windows\system32\cmd.exe");
if( !cmdFile.exists() )
{
QMessageBox::information( this, tr( "Information" ),
tr("Failed to find the cmd.exe ... Check cmd.exe is installed and is in C:\Windows\system32\ !"));
return;
}
QStringList arguments ;
arguments << " /c" <<"c:\temp\upgradeTesting\test.bat"<< fileName ;
QProcess *process = new QProcess( this );
process->start( cmdFile.absoluteFilePath(), arguments ) ;
if( !process->waitForStarted() )
{
QMessageBox::information(this, tr("Information"),
tr("Failed to start the process for upgrading!"));
return;
}
QMessageBox::information(this, tr("Information"),
tr("Please wait while system is upgrading .. click Ok to exit this box"));
qDebug() << fileName ;
process->waitForFinished() ;
qDebug() << process->readAllStandardOutput();
QMessageBox::information( this, tr( "Information" ),
tr( "Upgradation is successful.. Please restart the system") ) ;
process->deleteLater();
}
I have writen a batch script(.bat) which executes command like
我写了一个批处理脚本（.bat），它执行像
pscp -pw "lol" "%TARGET_UPDATE%" squire@"%TARGET_IP%":"%BASE_DIR%"/
For executing bash script via batch file below is the command inside batch file
下面是通过批处理文件执行 bash 脚本的批处理文件中的命令
putty -pw "lol" -m test-update.sh squires@"%TARGET_IP%"
i have even tried something like that
我什至尝试过类似的事情
C:\Program Files\putty.exe -pw "lol" -m test-update.sh squires@"%TARGET_IP%"
Could you guys please let me know where am i making mistake?
你们能不能让我知道我哪里出错了？
thanks and regards,
Sam
谢谢和问候，

I think it is easier to use QProcess::execute(QString cmdstring) Than you can also pass arguments to the Batchfile itself
我认为使用 QProcess::execute(QString cmdstring) 比您还可以将参数传递给 Batchfile 本身更容易
test.cpp
测试.cpp
QFileInfo cmdFile( "C:\Windows\system32\cmd.exe");
QProcess *process = new QProcess( this );
process->execute(cmdFile.absoluteFilePath() + " /c helloparam.bat \"my param\" ");
process->waitForFinished() ;
qDebug() << process->readAllStandardOutput();
helloparam.bat
你好参数文件
@echo off
echo hello %1
Info: To test this in your IDE make shure that you are running your application.exe from the release folder and have the batch file also in that folder
信息：要在您的 IDE 中对此进行测试，请确保您正在从发布文件夹运行 application.exe 并将批处理文件也放在该文件夹中

You can't call waitForStarted()twice per run. If waitForStarted()returns false you're returning from method execution. So after if( ! waitForStarted()your process is running.
waitForStarted()每次运行不能调用两次。如果waitForStarted()返回 false，则您正在从方法执行中返回。所以在if( ! waitForStarted()你的进程运行之后。

After spending many hours , I realised i need to give full path name in the batch script for Qt to execute it. Without qt it works fine but if I want to run batch file via QT app then I guess I need to give fully qualified path name of the bash script. example
花了很多时间后，我意识到我需要在批处理脚本中给出完整的路径名，以便 Qt 执行它。如果没有 qt，它工作正常，但如果我想通过 QT 应用程序运行批处理文件，那么我想我需要提供 bash 脚本的完全限定路径名。例子
putty.exe -pw "lol" -m C:\temp\upgradingTest\test-update.sh squires@"%TARGET_IP%"
instead of
代替
putty -pw "lol" -m test-update.sh squires@"%TARGET_IP%"
