问题 Since fabric is based on paramiko, is there any API to connect to virtual appliance with ssh-process having weird interactive shells ? How can fabric interact with processes acting as such shells. e.g. VM acting as switch having prompt 'switch-> ' when login is done over ssh. fabfile.py need to feed commands thereafter. once such command is to deploy images over tftpboots. The VM provides both telnet/ssh interface with user/password) I tried below code, but it does not work - @task taskA():

问题 I seem to be running into a situation with my custom Bash Prompt, very similar to this one here: Bash prompt line wrapping issue I'm thinking escaping might be my issue (as mentioned in the url above) I've tried moving things around and removing my brackets, but all that does is mess up my bash prompt. Is someone able to lend a hand with this: "What! \[\e[1;33m\]\w\[\e[m\]\[\e[37m\]\$(parse_git_branch)\[\033[00m\] \e[m\]$ " 回答1: All non-printing segments in the must be surrounded by \[...\]

问题 I'm trying to make a batch file that will compare two folders "core" and "custom" and return the names of the files that aren't in custom. So far I have this code, most of which is taken form another question on stack overflow. It creates "Arrays" of the files in each folder. How can I compare them? @echo off setlocal enableDelayedExpansion ::build "array" of folders set folderCnt=0 for /f "eol=: delims=" %%F in ('dir /B core') do ( set /a folderCnt+=1 set "folder!folderCnt!=%%F" ) ::print

问题 I am under Ubuntu 12.10, and I have installed this git-prompt-aware: https://github.com/jimeh/git-aware-prompt Whenever I am in a directory which has a git repository, I need to do source ~/.bash_profile to show the branch. If I don't do that, it doesn't show up. However, when I close the terminal and I go to the same directory, I need to do again the ~/.bash_profile , any thoughts why can this be happening? My problem is that in the .bashrc I already have defined PS1 as: case "$TERM" in

问题 I would like to create an effect in visual studio where text shows up on the screen not all at once, but letter by letter with a certain amount of time between each letter appearing. I plan to open a different module that will have this code in it from my main module. Any ideas? Here is my coding so far. I am making a command prompt. Public Sub Main() Dim line As String Console.Title = "Command" Console.WriteLine("Microsoft Windows [Version 6.3.9600]") Console.WriteLine("<c> 2013 Microsoft

问题 *Note: I'm using windows, so EOF is ctrl + Z for me. For a while I've noticed an EOF input seems to behave differently in isolation than it does when accompanied by other input. For example, ^Z (the EOF command for windows in command prompt) and a^Z seem to cause different behavior in the following code: #include <stdio.h> #define MAX 1000 int getline(char s[]); main() { int line; char arr[MAX]; while( (line = getline(arr)) != EOF) printf("%s",arr); system("Pause"); return 0; } int getline

问题 I am using a simple script to edit an existing image. No matter what I do, a save prompt always comes up. I want this to be 100% automated. save() gives me a saveAs prompt to save it as a copy. close(SaveOptions.SAVECHANGES) just gives me a generic "Do you wish to save before closing?" box that I still need to select Yes on. saveAs() gives me the same as save(), except I can toddle the "As copy" option off... but that still doesn't help. 回答1: Try this instead: // where fPath is your file path

问题 I've made udp based client and server sample programs with C. My codes are followings [Server] #include <stdio.h> #include <string.h> #include <errno.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <netdb.h> #include <arpa/inet.h> int printerror2(char func[], int errnum) { printf("%s error = %d:%s\n", func, errnum, strerror(errnum)); perror(func); return errnum; } int printerror(char func[]) { return printerror2(func, errno); } int main(int argc, char *argv[
