i cant able to mount my pendrive using qprocess

[iswaryasenthilkumar]

i created one script file (script.sh) inside that file i have written the command to mount

sudo mount -o umask=0 /dev/sdb1 /media/usb

sudo mount -o umask=0 /dev/sdb1 /media/usb

To copy to clipboard, switch view to plain text mode 

i called this file using Qprocess,the result its mounted,

int  Widget::process()
{
    QProcess transcodescript;
    QStringList arguments;
    QString program ="/bin/sh";
    arguments << SCRIPTFILEPATH;
    transcodescript.start(program, arguments);
    status=transcodescript.waitForFinished(-1);
    if(!status)
    {
    qDebug()<<"failed to mount";
     }
    return SUCCESS;
}

int  Widget::process()
{
    QProcess transcodescript;
    QStringList arguments;
    QString program ="/bin/sh";
    arguments << SCRIPTFILEPATH;
    transcodescript.start(program, arguments);
    status=transcodescript.waitForFinished(-1);
    if(!status)
    {
    qDebug()<<"failed to mount";
     }
    return SUCCESS;
}

To copy to clipboard, switch view to plain text mode 

i dont get any error for this above command,but when i use that command in terminal its get mounting,,i know am doing some mistakes please can any one give me solution for this.
Thanks in Advance

In the case of manual invocation you might have used sudo before and entered the password there so you were already authenticated when sudo of the script ran.

You could try using the -S option to make sudo ask for the password on stderr and read it from stdin, or provide a program to --askpass or configure one (all documented in the sudo man page).

Of course using sudo assumes that the user running you program has the permission to use sudo to gain elevated privilegdes.
But then again, even having code to mount suggests that you are not targetting a desktop system but more likely some custom setup and can configure the system appropriately.

Cheer,

If SCRIPTFILEPATH is a relative path then the whole thing could be failing* because the current working directory is not where you think it is.

*your original post indicates that everything is working but I assume it is not.
