    Bash script in c

    Hi! I'm trying to call another c program via shell script in c, but it just pop-up and close again.. here's my code:

    char* command = "";        
    char temp[MAX_LENGTH] = "";        
    sprintf(temp, "gnome-terminal -e 'bash -c \"./Isopropyl %s\"'", editor -> filename);
    command = malloc(strlen(temp) + 1);
    if(command == NULL)
    strcpy(command, temp);

    Edit: The title is incorrect I'm sorry, It should be "Shell script in c"

    You don't need any of that command stuff.

    You can just do system(temp); after the sprintf.

    You should also do
    printf("Cmd=%s\n", temp);
    as well, to verify what you're actually trying to pass off to gnome-terminal.

    You should also verify that Isopropyl is also in the current working directory.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
