问题 I know you can clear the shell by executing clear using os.system , but this way seems quite messy to me since the commands are logged in the history and are litterally interpreted as commands run as the user to the OS. I'd like to know if there is a better way to clear the output in a commandline script? 回答1: print "\033c" works on my system. You could also cache the clear-screen escape sequence produced by clear command: import subprocess clear_screen_seq = subprocess.check_output('clear')

问题 I have cloned a parent repository ' objc4 ' from https://github.com/RandomDSdevel/objc4 to the local path ' /Volumes/Development/Repositories/objc4 .' This parent repository contains a submodule ' OBJC4-437.1-Runtime ' which I have set up to mirror the contents of https://github.com/macmade/OBJC4-437.1-Runtime at the local path ' /Volumes/Development/Repositories/objc4/runtime .' I would like to merge this submodule into its parent repository and have already attempted to do so using these

问题 I'm learning how to use ncurses and I'm in a weird situation. It seems my output can't go over 24 lines. Moreover, whenever I run my software, and the execution finishes his job, my terminal stops working as before, and I have 2 different situations: if I've launched my run from a line behind line 24 I can use the terminal, but if I keep scrolling when at the last line of the window, nothing more happens: all input and output keep happening in the last line, without any new line appearing at

问题 I am trying to determine WHAT console I am running in. (Exceptionally hard based on the research I have done so far.) The latest feature that I discovered that would be useful is Double High, Double Wide for a couple of scenarios. The setup is a Kubuntu 15.04 machine with native (lower) and remote access via Terminal.app on OS X 10.10.4. Based on vt100.net Apple is doing the right thing. #!/bin/bash # Cool effect with OS X Terminal.app # Not as much on others (Like Konsole) function embiggen(
