terminal

问题 Very often (every time really) after I use the command git log my terminal becomes unresponsive to further input, this is on OSX. Is there a command that I don't know about that will make the terminal active again instead of just quitting the terminal and starting over? 回答1: You are inside a program that displays the log without scrolling, most likely less , which can be exited by pressing the q key. 回答2: Just press q to quit from less . 来源： https://stackoverflow.com/questions/6005054/why

问题 We are writing a Xamarin.Mac application. We need to execute a command like "uptime" and read it's output into an application to parse. Could this be done? In Swift and Objective-C there is NTask, but I don't seem to be able to find any examples in C#. 回答1: Under Mono/Xamarin.Mac, you can the "standard" .Net/C# Process Class as the Process gets mapped to the underlaying OS (OS-X For Mono, MonoMac and Xamarin.Mac, and Mono for *nix).

问题 I've already got ruby and rails installed for some time and worked on some projects. Lately I've installed the Xcode 5 developer preview in order to get my apps ready for iOS 7. I'm just mentioning this in case the new Xcode messed it up. I first noticed the error when trying to rake asets:precompile in the rails project directory. It gives the following error: /Users/User/.rvm/bin/ruby: line 6: /Users/User/.rvm/bin/ruby: Argument list too long /Users/User/.rvm/bin/ruby: line 6: /Users/User/

问题 gcc4.9 supports the colorizing diagnostics for compiler warning/error messages. We can enable it for a particular program using the option " fdiagnostics-color ". Currently I am using gcc4.9.1 and I append this particular option in my makefile as follows: CC = /home/mantosh/gcc-4.9.1/bin/g++ -std=c++1y -Wall -pthread DFLAG = -g -gdwarf-2 -fdiagnostics-color=always OUTFILE = test $(OUTFILE): test.cpp $(CC) $(DFLAG) -o $(OUTFILE) test.cpp clean: rm -f *.o $(OUTFILE) If I compile a *.cpp file a

问题 I would like to print (☞ﾟヮﾟ)☞ with the Ncurses library using C++ in Ubuntu. First of all, you can do this by simply having: std::cout << "(☞ﾟヮﾟ)☞" << std::endl; And it works just fine. However, when printing using Ncurses, I think that you need to use printw(char[]) . In which case, I try something like this: std::string str = "(☞ﾟヮﾟ)☞"; // String initscr(); // Start curses mode printw(str.c_str()); // Print getch(); // Wait for input endwin(); // Exit curses mode But it outputs: (�~X~^��~ �

问题 Using Python , I would like to start a process in a new terminal window, because so as to show the user what is happening and since there are more than one processes involved. I tried doing: >>> import subprocess >>> subprocess.Popen(['gnome-terminal']) <subprocess.Popen object at 0xb76a49ac> and this works as I want, a new window is opened. But how do I pass arguments to this? Like, when the terminal starts, I want it to say, run ls . But this: >>> subprocess.Popen(['gnome-terminal', 'ls'])

问题 I'm attempted to resize the terminal window on launch of a python script to ensure the display will be static size. It's working but not quite what I expected. I've tried a few methods: import sys sys.stdout.write("\x1b[8;40;120t") and import subprocess subprocess.call(["echo","-e","\x1b[8;40;120t"]) and even just print "\x1b[8;40;80t" They all work and resize the real terminal. However, if my terminal is, let's say 25x80 to start, the script starts, it resizes, then exits. It will not

问题 I am developing a robot that accepts commands from network (XMPP) and uses subprocess module in Python to execute them and sends back the output of commands. Essentially it is an SSH-like XMPP-based non-interactive shell. The robot only executes commands from authenticated trusted sources, so arbitrary shell commands are allowed ( shell=True ). However, when I accidentally send some command that needs a tty, the robot is stuck. For example: subprocess.check_output(['vim'], shell=False)
