问题 If I run something that returns with a & or some other character that has special meaning, and I try to use it in a script, how would I escape it? An example would be if I shared a local account with someone in the same computer, and I had a username that says John & Matt. Putting a batch file in the Desktop directory that had something like this: @ECHO OFF echo %~dp0 It would return something like this: C:\Users\John The system cannot find the path specified. And the whole script from that

问题 Ok, I need to use this for graphical programming, GUI, for cs 349 uwaterloo first assignment. I see random Xlib.h and Xutil.h files lying around on google search results. But no where does it say how I install or download Xlib from some website of something. I even tried to copy paste the Xlib.h onto a new files I created in my blank project and it has more than 100 errors. So... what do I do? 回答1: Simpliest way is to install cygwin - you'll get gcc + other tools (binutils, make, autotools)

问题 I'm trying to delete some files in a WinRar Archive using the Command Line. The Rar-File: /testing.rar /testing.rar/some-data.txt /testing.rar/testing/some-data.txt Here's my Code: cd "C:\Program Files\WinRAR\" && rar d -cl -r "c:\full\path\testing.rar" some-data.txt It only deletes the some-data.txt file in the root, not inside /testing/ When using cd "C:\Program Files\WinRAR\" && rar d -cl -r "c:\full\path\testing.rar" some-data.* (changed the extension to .*) it does delete both files.

问题 I have an R script that I would like to run from the command line using Rscript.exe in Windows. The script runs fine if I open it in RStudio but when I run it through Rscript in the command line it fails because I have UNC paths in my script. For example, read.csv("//server/directory/file.csv/") Rscript fails and says the directory does not exist. Is there anyway to resolve this problem? 来源： https://stackoverflow.com/questions/37702472/rscript-and-unc-paths

问题 I am trying to pipe the content of a file to a simple ASCII symmetrical encryption program i made. It's a simple program that reads input from STDIN and adds or subtracts a certain value (224) to each byte of the input. For example: if the first byte is 4 and we want to encrypt, then it becomes 228. If it exceeds 255, the program just performs some modulo. This is the output I get with cmd (test.txt contains "this is a test"): type .\test.txt | .\Crypt.exe --encrypt | .\Crypt.exe --decrypt

问题 My searches have only shown me how to create symbolic links using mklink in cmd. I have seen some things saying to use readlink , but PowerShell and cmd don't know what readlink is, and cd obviously doesn't work. So how do I follow one? 回答1: For your question i made this batch file: mkdir truedir dir > truedir\fileone.txt mklink /d symdir truedir cd symdir dir And i have found no problem to get the content of the symblic link to a directory from command prompt. No problem also with powershell
