问题 is there a way in C# to rename System.Console.WriteLine so that in my C#/console/visual studio program I could write printf("hello"); //instead of System.Console.WriteLine("Hello"); //?? What would this be, a class? a namespace? Do I do this in the header or inside of main? 回答1: Your target looks strange and there is no way to do this in c#. Alternatively you can add a method in a class and use it. private static void printf(string value) { System.Console.WriteLine(value); } Note: above

问题 This question already has answers here : Find and replace with sed in directory and sub directories (7 answers) Closed last year . My question is how can I change one word in many txt files in one directory and multiple subdirectories in BASH? I did as below (check all similar topics) but it is still not working. changePhrase is a name of directory where the subdirectories and files are. Inside that files there is a string that I want to change. I have to make it with a for loop (it's a task)

问题 I'm following a tutorial on connecting a java class to MySQL (http://zetcode.com/db/mysqljava/). I can get the code to compile and run in Eclipse, but I'm doing something wrong when trying to run it at the command line. I'm using OSX's terminal btw. I perform the following to compile cd dropbox/workspace/mysqltut/src/zetcode javac Version.java This successfully creates the Version.class file. The simple version of my question is, how do I run this from the command line? The following details

问题 This is my first question on stackoverflow. Pardon me if I haven't searched properly but I do not seem to find an explanation for this. Was just attempting an example from Bjourne Stroustroup's papers. Added my bits to see the array get re-sized as I type the text. But it doesn't seem to work that way! getchar() simply waits till I am done with entering all the characters and then it will execute the loop. As per the logic, it doesn't actually go into the loop, get a character, perform its

问题 I'm writing a program in curses and sometimes happens that if I leave the program opened and I use other terminal tabs for a while, when I go using the program again it seems like it has refreshed something and something has disappeared... I cannot show pics or screenshots because I haven't understood yet well when and how it happens... Is there a way to prevent or fix this? 回答1: screen.getch reads from stdscr , and if it refreshes (due to any change on the screen), will overwrite boxes . You

问题 I've got a problem with ANSI escape codes in my terminal on OpenSuse 13.2. My Makefile use to display pretty colors on OSX at work but at home when I use it I get the litteral termcaps such as \033[1;30m ... \033[0m I know close to nothing about termcaps, I just found these escape characters that seemed to be working fine ! The strangest is that both my OSX and Linux terminal are configured with TERM=xterm-256color so I really don't know where to look for the correct setting I'm currently

问题 I'm working on a small script. The script should open 3 terminals and interact with this terminals independently. I am pretty understand that subprocess is the best way to do that. What I've done so far: # /usr/bin/env python import subprocess term1 = subprocess.Popen(["open", "-a", "Terminal"], stdin=subprocess.PIPE, stdout=subprocess.PIPE) term1.communicate(input="pwd") My problem is I cannot interact with a new terminal. this part term1.communicate(input="pwd") is not working. I cannot
