It is for sh so that it reads commands from argument strings. Check "this":http://manpages.ubuntu.com/manpages/utopic/en/man1/sh.1posix.html man page for more details. I hope your system has sh command.

QProcess Class is used to start external programs and to communicate with them.
create a new QProcess and input args to /bin/sh.
Below code has been tested working.
Thanks to p3c0, if not, answer below will not be available :QProcess *myProcess = new QProcess; QStringList args; args<"-c"<<"sudo -S ifconfig eth0 192.168.100.1 < /var/passwd.txt"); myProcess->start("/bin/sh",args);
