Command line fuckery

Name: Anonymous 2007-10-16 9:23

I want to write several lines to the console, but after each line, I want to clear the screen and then write the next line. From what I gather I can use the "\x08" character (backspace) to achieve this. How do I cleared screen?

Take a cloth and clear the screen before the new line is written. If you can't clear the screen soon enough, use sleep(x).

while true ; do clear ; echo "desu"; clear ; echo " desu" ; clear ; echo "  desu" ; done

\r on the correct OS does the job

\r is just a carriage return, I'm pretty sure it doesn't do that on *any* operating system. For reference, it doesn't work as you described on either Windows or BSD. I can't speak for any other backwards operating systems.

Happen to have an example of how to use this? I can't get it to work -

#include <cstdio>

int main( int argc, char* argv[] ) {
    char p[] = { 0x9b, '2', 'J', 0 };
    printf( "%s%s", "DESUDESUDESU", p );
    return 0;
}

Output: DESUDESUDESU›2J

Actually, you know. It might just be that I'm using a ssh client which can't handle the escape codes properly. I should consider getting something that isn't a piece of shit.

Try 27,'[' instead of 0x9b.

If you want to write just one line and then have the next line replace that one, you could use non buffered output functions like write instead of printf and such.

Because basically that's what you're saying, write one line then clear the screen and write the next one. That would be exactly the same as overwriting the last line, just figure out how long you have to write by getting information about the terminal size.

That's what you get for using a cudder based... wait, you weren't? No wonder Ctards are scared of Lisp! They can't handle a single level of nesting.

Since you forgot a parenthesis, you will spend the rest of your life falling or being crushed by strong gravity. Your choice.
