working-directory

问题 I upgraded to RStudio 1.0.44 and it seems knitr::opts_knit$set(root.dir = path) where path is my directory is not working as before. It throws a message: The working directory was changed to /... inside a notebook chunk. The working directory will be reset when the chunk is finished running. Use the knitr root.dir option in the setup chunk to change the the working directory for notebook chunks. This message will now appear in every following command. Note that I am not knitting the rmd yet.

问题 What is the difference between Current Directory and Working Directory in Windows? How can one change working Directory for applications like Notepad++ or Mozilla Firefox? 回答1: Current directory and working directory are just two different names for the same thing. Each process maintains a single current directory. The current directory is specified on startup as a parameter to whichever function is used to create the process, for example CreateProcess . How do you change the current

问题 I'm using os.system() to do Windows command line shell executions. I would like to change the Windows cmd current directory. Here's one way of doing it: os.chdir('newPath') But chdir() will also change the actual Python current working directory. I don't want to change the actual Python working directory because I want other parts of my script to run in the original current working directory. What I want to change is only the Windows cmd current working directory. In other words: I want os

问题 I have a common command that gets called from within very specific directories. There is only one executable sitting in /bin for this program, and the current working directory is very important for running it correctly. The script affects the files that live inside the directory it is run within. Now, I also have a custom shell script that does some things in one directory, but I need to call that command mentioned above as if it was in another directory. How do you do this in a shell script

问题 I hope you will get my problem, dont know if I can describe it properly in english, but I will try :) Situation: Folder Structure: MainFolder/Sub1/Sub2 2 exe files: MainFolder/MainProg.exe and /Sub2/SecondProg.exe MainProg.exe is not from me, I wrote an .cs file inside /Sub1, kind of a plugin. (I think MainProg.exe kind of works like a compiler, cause it has a log window where I can see errors from my .cs file.. I think the author somewhere mentioned a JIT compiler ?!) Start MainProg.exe ->

问题 I want to get the current directory of the topmost Terminal tab/window (via AppleScript or something else, it doesn't really matter). How can I do that? 回答1: Another solution. get_foregroundterminal_curdir_fast.scpt: tell application "Terminal" do shell script "lsof -a -p `lsof -a -c bash -u $USER -d 0 -n | tail -n +2 | awk '{if($NF==\"" & (tty of front tab of front window) & "\"){print $2}}'` -d cwd -n | tail -n +2 | awk '{print $NF}'" end tell I use lsof itself to get PID of the bash shell

问题 As we know WPF OpenFileDialog no more changes the app's working directory and RestoreDirectory property is "unimplemented". However, upon subsequent open, its initial directory is default to the last opened file rather than the original working directory, so this information must be stored somewhere. I wonder is it possible to get/set it from user code? 回答1: On Windows 7 the recent file information is stored in the registry at this key: HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer
