一个人想着一个人 提交于 2020-05-15 02:34:47
问题 I'm using the following class from my JavaFX Tutorial: import javafx.application.Application; import javafx.stage.Stage; public class HelloFXApp extends Application { public static void main(String[] args) { // Launch the JavaFX application Application.launch(args); } @Override public void start(Stage stage) { stage.setTitle("Hello JavaFX Application"); stage.show(); } } I'm using Ubuntu and I have the correct path to my .java file in my Terminal.. When I type "javac HelloFXApp.java" it works

Clearing the screen by printing a character?

我的未来我决定 提交于 2020-05-09 21:41:46
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

can't brew install node

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 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . I am writing my own tar archiver. All works fine inside my app (even reading tars generated with other tools) however I cannot get my tar files to work with 3rd party tar file readers. So I tried building a tar file on the command line, building one with my code and binary comparing the two. But there seems to

In a script how to get the pid of spawned terminal's shell to execute commands in it using ttyecho?

随声附和 提交于 2020-04-30 10:01:54
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

Is it possible to implement printf() in a non blocking manner in linux terminal

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
