Run bash script from qt

Wasee

Hi everyone;
I am running the bash script from qt creator and following the code.
/@
QProcess process ;
process.startDetached("/bin/bash", QStringList() << "/home/Documents/testing/script.sh");
@/
But getting error No directory found even my directory path is correct.
thanks

process.startDetached("/bin/bash", QStringList() << "-c" << "/home/Documents/testing/script.sh");

So you're sure that directory path is correct and exists, it isn't supposed to be "/home/my_user_name/Documents/..."? :)

@jsulm Hi;
This is the error:
/bin/bash: /home/Documents/testing/script.sh: No such file or directory

thanks

/home/Documents/testing/script.sh

As @JonB said: this path looks wrong. There should be user name in it, like: /home/YOUR_USER_NAME/Documents/testing/script.sh

auto docu_path = QStandardPaths::writableLocation( QStandardPaths::DocumentsLocation );
process.startDetached("/bin/bash", QStringList() << QString( "%1/testing/script.sh").arg( docu_path );

@jsulm @JonB @JoeCFD Hi;
My application crashes with ASSERT failure in QList<T>: index out of range.
The program has finished unexpectedly.

Then fix your code.
You are accessing your QList outside of its bounds.
Really not hard to fix, instead of wasting time asking such basic stuff in a forum...
And do you really think you provided enough information for others to help you?
How should anybody know what list it is and how you are using it if you don't even bother to show relevant code?

Hi everyone;
I need to pass the arguments with bash script from qt. How its will possible with following example.
/@
process.startDetached("/bin/bash", QStringList() << "-c" << "/home/Documents/testing/script.sh");
@/
thanks

QProcess::startDetached("/bin/bash", QStringList() << "-c" << QString("/home/johann/script.sh %1").arg(someParameter));

@Wasee
@jsulm's code is correct. However, there will be a "wrinkle" if your someParameter argument has any spaces in it. I don't want to complicate things unnecessarily, so if that is the case let us know, otherwise just follow that code.
