    Default Shell script execution using Qprocess

    I am trying to execute a shell script using qprocess that calls another shell scripts. The problem is that the program skips any other calling to other scripts and executes the next command
    The script:
    Qt Code:
    1. #tri1 decoding
    2. utils/mkgraph.sh data/lang_test exp/tri1 exp/tri1/graph
    3. echo "Hi there"
    To copy to clipboard, switch view to plain text mode 

    The code i wrote:
    Qt Code:
    1. QStringList program ;
    2. program<< "-c"<<"bash /home/dell2/Desktop/ll.sh";
    3.  
    4.  
    5. QProcess exec;
    6. exec.start("/bin/sh",program);
    7. exec.waitForFinished();
    To copy to clipboard, switch view to plain text mode

    You probably have to set a working directory - setWorkingDirectory()?

    Hi, just a small remark: you effectively call "sh -c bash /home/dell2/Desktop/ll.sh", which means that you start a shell (sh) to start a shell (bash) to run your script. One of these shells can be removed.
