QT plain command execution like system
I have a pretty complicate command list, which loads a virtual env and executes several commands on a given text. It works fine with system() but fails with QProcess::execute. This is a bummer since I want to use
QProcess process;
process.readAllStandardOutput();
to read the output without messing with pipes. Is there a way to give a process just a "stupid" command string, which it executes like system() ?
command = "bash -c \"" + prepend + "\\\"" + text + "\\\"" + append + "\"";
std::cout << command.toStdString().c_str() << std::endl;
//qDebug() << QProcess::execute(command.toStdString().c_str());
system(command.toStdString().c_str());
QT seems to mess up the parameters:
usage: program_name [-h] [--list_models [LIST_MODELS]] [--text TEXT]
Edit1: solution with popen (ugly but working):
FILE *fp;
char path[1035];
fp = popen(command.toStdString().c_str(), "r");
if (fp == NULL)
{
printf("Failed to run command\n" );
exit(1);
}
while (fgets(path, sizeof(path), fp) != NULL)
{
QString line = path;
if(line.contains("Keyword"))
{
qDebug() << "=============================";
qDebug() << line;
qDebug() << "=============================";
}
}
pclose(fp);
Edit2: Requested debug output

As pointed out elsewhere the basic problem is that QProcess goes to some trouble to avoid going through any shell. Having said that you should be able to achieve what you want by invoking a shell explicitly.
Let's say the command you would usually run under bash is ls -l | grep '\.' ...
QProcess process;
QString shell_command = "ls -l | grep '\.'";
process.start("bash", { "-c", shell_command });
Now you can read the command's standard output/error streams as you would with any other QProcess.
[Note that this is more or less the Qt version of a previous post.]
