How to run "more" command using Qprocess ???

[jesse_mark]

Hello guys,

I am trying to run the "more" command in Linux using the Qprocess

what i have been trying is :

......  
         .......
          myProcess->setWorkingDirectory(ui->LE_workingdir->text().trimmed());
          myProcess->start("/bin/sh");
          myProcess->write("more filename\n\r");
 
// I have the slots to get all the reads from the process
    }

......  
         .......
          myProcess->setWorkingDirectory(ui->LE_workingdir->text().trimmed());
          myProcess->start("/bin/sh");
          myProcess->write("more filename\n\r");

// I have the slots to get all the reads from the process
    }

To copy to clipboard, switch view to plain text mode 

but i am not getting any info, please any idea what is wrong i am doing here

Thank you so much for taking time to read this


I also tried
myProcess->start("/bin/sh", QStringList()<< "-c" << "more filename"));
and
myProcess->start("/bin/sh", QStringList()<< "-c" << "more" << "filename"));

but it didnot work too

What exactly would you expect to receive as a result of such command?

[jesse_mark]

its a log file i expect to receive numbers and when i run the commend in the terminal it works fine and i got the result it want

$ more filename

result i got list of numbers such as :
871
881
891
901
911
921
941
951
....

But with QProcess you don't have a terminal.

If you want to have the content of a file, why don't you just read it with QFile?

[jesse_mark]

with this way is faster, to use the more command.
but with this way i can run the ifconfig command and get its out, so why can not i use the more command ??

so it is not possible to use the more command using qprocess ??

I don't understand what you mean.

but with this way i can run the ifconfig command and get its out, so why can not i use the more command ??

ifconfig doesn't require a terminal, more does.

so it is not possible to use the more command using qprocess ??

Certainly not the way you are trying to do it. Either launch a terminal and execute more there or if your app is launched from a terminal, find a way to attach to this terminal and launch more there.

Thanks but could you please tell me how can i launch a terminal using qprocess and execute "more" in it ??

Most probably by making QProcess run "xterm -e more filename" or something similar.

this command did open a terminal and run the command, but the Qprocess didn't read any output.
what i really want is to make the qprocess receive the out put of the command so i can display it where i want.

Thank you

Why would it read any output?

Then use QFile like I already told you.
