问题 I'm using chez-scheme and I can't find a way to clear the screen completely. (If someone knows a better way than printing I'd be interested in that too but it's not my question here) From what I can find clearing the screen by ^L (control-L) or giving the clear command (in bash at least) is equivalent to outputting ASCII character 12: Form feed . However, printing this does nothing. If I use (display (integer->char 12)) it just prints a newline . Another way to encode this character is \f

问题 I am trying to upgrade my node via homebrew but ran into a problem because I think I tried to download through the website. I am very new to terminal. I've tried to search for answers but many people say you can just delete the unbrewed header files. I am not sure how to do that. but for some reason when I try to brew install node, it says the brew link step did not complete successfully. I also tried to brew link node but that doesn't work either. I ran out of options so I came here.

问题 I am using ttyecho (can be installed with yay -S ttyecho-git ) to execute a command in a separate terminal like so: urxvt & sudo ttyecho -n /proc/<pid-of-new-urxvt>/fd/0 <command> It does not work because the /proc/pid-of-new-urxvt/fd/0 is a symlink that points to the /dev/pts/x of the parent terminal. In the spawned urxvt I happen to run zsh. So if I use the pid of that zsh process it works: sudo ttyecho -n /proc/<pid-of-new-zsh-within-new-urxvt>/fd/0 <command> How can I get the pid of the

问题 I have a printf statement after sleep for 1 second. Since the printf statement takes longer than 1 second , the refresh rate is more than 2 seconds. Here is an example i am talking about : while(1){ printf("%s",buf);//Takes more than one second to print a table. Only few //values are updated sleep(1); } How can i have a printf to be non blocking. Is there a way in a standard linux machine ? -Sanatan 回答1: If you only care about what shows on the screen, that is one of the problems that curses
