Here's the scenario.
I am on the unix command line (in home directory). I want to browse the directory through
$ vim .
thus opening the vim netrw.
Now I am browsing the directory using the netrw.
What I want here is that when I exit vim netwr, I want my previous current working directory (in this example the home directory) to now become the directory I was previously in vim netrw.
Example:
step 1. now in home directory
step 2. vim . (thus opening vim netrw)
step 3. go to any directory (~/my/other/folders)
step 4. :q (to exit vim)
step 5. (here, I want my previous directory to now become ~/my/other/folders
any ideas on how to do it? I was thinking of doing something in .vimrc but I dunno how. Been into google search, but found nothing valuable.
A possible solution would be to change the current work directory while in netrw by pressing c, and spawn a new shell from the folder you're in by issuing :shell
So it would look like:
vim .
Navigate to the desired folder...
c
:shell
And there you are in a shell in the current folder you were in netrw.
And when you exit that shell, you fall back to where you were in netrw and can continue using the explorer.
I don't think it's possible at all. Every command executed via system('command') or :!command is executed through a subshell, not through the shell that started Vim so I don't see how you could alter the host shell in any way.
But I smell an XY problem here. What is your goal?
Do you want to be able to execute some commands on the files you just edited and you want to be in their directory? If so, do you know about :sh? :!command?
Do you want a "graphical" file explorer for your shell? If so, do you know vifm? Ranger? Midnight Commander?
To add to Wadih's answer, you can put this in your .vimrc file:
let g:netrw_keepdir=0
This means the working directory will be automatically updated and you don't need to press c each time.
So after navigating to a folder in netrw, all you need to do is do this:
:sh
And this opens the terminal in the current folder.
From the netrw help file:
By default, g:netrw_keepdir is 1. This setting means that the current
directory will not track the browsing directory. (done for backwards
compatibility with v6's file explorer).
Setting g:netrw_keepdir to 0 tells netrw to make vim's current directory
track netrw's browsing directory.

I'm new to R and RStudio and am currently taking online classes to learn more about data science. In one of my lectures, I'm being asked to create a project in RStudio prior to creating a repository in github and linking the project with git. In order to make a pre-existing project interact with git, the instructions in my lecture are telling me to navigate to the directory containing my project file by using the "cd" command followed by the location of the file and file name. My project file is currently located on my desktop so I typed in "cd ~ /Desktop/temporary_no_version_control" however, the directory doesn't seem to change and remains set on the original location of the file which was in Users/savannahkeiffer. Just so I could complete the assignment, I re-located the file to my user file and tried to follow the rest of the instructions which told me to type "git init" followed by "git add ." which is where I run into the "warning: could not open directory" warning.
I have a macbook which runs on OS X Maverick. I went into my system preferences > security and privacy and selected Full Disk Access where I manually allowed terminal to have access to all the files on my laptop. However, after closing and re-opening RStudio and attempting the commands again, I got the same error.
This is what I entered when I tried to change the directory
Savannahs-MacBook-Air-2:~ savannahkeiffer$ cd ~
/Desktop/temporary_no_version_control
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git init
Reinitialized existing Git repository in
/Users/savannahkeiffer/.git/
And what I got when I changed the location of the project on my laptop in order to complete the assignment (after already giving access to terminal)
Savannahs-MacBook-Air-2:~ savannahkeiffer$ cd ~
/Users/savannahkeiffer/first project/temporary_no_version_control
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git init
Reinitialized existing Git repository in
/Users/savannahkeiffer/.git/
Savannahs-MacBook-Air-2:~ savannahkeiffer$ git add .

Support/CallHistoryTransactions/': Operation not permitted
warning: could not open directory 'Library/Application
Support/com.apple.TCC/': Operation not permitted
warning: could not open directory 'Library/Application
Support/AddressBook/': Operation not permitted
And so on.. Is this a directory problem or a "git add ." command problem?
It looks like what happened is that when you typed the cd command, you left a space in between the tilde and the rest of the path, so you changed back into your home directory (represented by the tilde). Then, when you tried to do a git init, you tried to initialize your home directory as a Git repository, and then ran into the fact that macOS restricts some programs (in your case, not Terminal, but maybe still Git) from accessing certain directories.
In the shell, the tilde is just a fancy way of spelling the environment variable $HOME, which points to your home directory (in this case, /Users/savannahkeiffer), so it should immediately precede the rest of the path without a space in between.
The best thing to do in this case is switch into your project directory and then initialize a repository there:
cd ~/Desktop/temporary_no_version_control # note the lack of space after the tilde
git init
If you didn't intend for your home directory to be a repository (i.e., you're not storing your dotfiles in a repository there), then you will probably also want to remove the .git directory from your home directory by running rm -fr ~/.git. Be careful when typing this, as rm removes data without prompting and an unfortunate space could result in all your data being deleted.
Hello this was an issue I had also but in Windows. It was a simple fix, user error. I hadn't used gitbash for awhile so I forgot the process with working in gitbash. First mistake I made was after opening gitbash I directly executed the git status command. That's when I got the "warning: could not open the directory" message. You need to using the cd (change directory) command and the dir (directory) command to navigate to the folder that has the files you want to "git add ." and "git commit -m". Once you get to that folder you will be able to use the "git status" command to see your changes then proceed as normal. I had to post this because it took me hours before I realized what I was doing wrong. No other stack post pointed this obvious user mistake. Hope it helps you.
I am spinning up an instance of rstudio server and I need the working directory of R to be a specific directory. I would also like the file pane in the bottom right corner to be pointing to the same directory. Is there a way to do this? Currently it runs from the home directory of whichever user is running the program. I have tried the --server-working-dir flag, and it does not seem to work. Here is the command I am using:
/usr/lib/rstudio-server/bin/rserver \
--server-daemonize=0 \
--server-user=user \
--server-working-dir=/some/path \
--auth-none=1 \
--auth-minimum-user-id=0
Any help would be useful here.
[edit] Just wanted to clarify that I would like the server to start in this directory. I am building a container that will be deployed multiple times, and I don't want the users to have to set their directories every time it is deployed.
If you want to modify the file pane in the right, you should edit /etc/rstudio/rsession.conf.
And add two lines in below:
session-default-working-dir=/some/path
session-default-new-project-dir=/some/path
You can do this by edditing the (global) R profile startup script. Here's a step by step guide:
1) Run Rscript -e "R.home()" -- this will tell you the location of your R directory home. In my case (Mac) it is /Library/Frameworks/R.framework/Resources
2) Go to /Library/Frameworks/R.framework/Resources/etc -- e.g., $R_HOME/etc
3) sudo touch Rprofile.site if it doesn't exist, then sudo nano Rprofile.site
4) Add the following lines and save:
cat("hi\n")
setwd("/some/path/")
You should avoid overwriting the users home directory.
Amongs the [.Rprofile] files you should only edit the Rprofile.site as a last resort since it acts globally.
Suggested solution:
R read the "initialization file" at start, in the following order:
.Rprofile.site
.Rprofile (located in the current directory).
.Rprofile (in the users home directory).
In your case if you are planning to login to R-Studio server you will end up in the users home directory, so I would suggest you to just edit the [.Rprofile] in the home directory. In case the [.Rprofile] is missing you need to create it.
Add this line in your .Rprofile [in your home directory]:
setwd ('/your/path/')
Logout/login to your R-studio server session and you will notice that the "file pane to the right location" has changed accordingly to what you specified in your .Rprofile.
How to change working directory in Julia Jupyter?
I tried and read everything, still have no idea how to do that. It only allows me to select directories under my home ~/ dir. I can't find any button to go up to /.
I'm pretty sure once you have started the server you cannot then go up directories, I may be wrong though.
So best thing to do is start the jupyter notebook server somewhere that contains all of the folders you might need -i.e. the root dir if you want to make sure you have access to everything.
You can use the --notebook-dir flag for this. Or you can set defaults in the config.
you need to create the config file, using cmd :
jupyter notebook --generate -config
Then, search for C:\Users\your_username\.jupyter folder (Search for that folder), and right click edit the jupyter_notebook_config.py.
Then, Ctrl+F: #c.NotebookApp.notebook_dir ='' . Note that the quotes are single quotes. Select your directory you want to have as home for your jupyter, and copy it with Ctrl+C, for example: C:\Users\username\JuliaProjects.
Then on that line, paste it like this : c.NotebookApp.notebook_dir = 'C:\\Users\\username\\JuliaProjects'
Make sure to remove #, as it is as comment.
Make sure to double slash \\ on each name of your path.
Ctrl+S to save the config.py file !!!
Go back to your cmd and run jupyter notebook. It should be in your directory of choice. Test it by making a folder and watch your directory from your computer.
I use Jupyter Lab and start it from the Julia REPL (1.4) like this:
using IJulia
jupyterlab(dir=pwd(), detached=true)
I have iPython Notebook through Anaconda. I accidentally deleted an important notebook, and I can't seem to find it in trash (I don't think iPy Notebooks go to the trash).
Does anyone know how I can recover the notebook? I am using Mac OS X.
Thanks!
This is bit of additional info on the answer by Thuener,
I did the following to recover my deleted .ipynb file.
The cache is in ~/.cache/chromium/Default/Cache/ (I use chromium)
used grep in binary search mode, grep -a 'import math' (replace search string by a keyword specific in your code)
Edit the binary file in vim (it doesn't open in gedit)
The python ipynb should file start with '{ "cells":' and
ends with '"nbformat": 4, "nbformat_minor": 2}'
remove everything outside these start and end points
Rename the file as .ipynb, open it in your jupyter-notebook, it works.
The "delete" functionality now sends the file to OS trash rather than permanently deleting it, see this PR: https://github.com/jupyter/notebook/pull/1968. So you can just open your Trash (wherever that is on your system) and restore it.
I think the easiest way (until developers handle this issue) to retrieve your Ipython history is to write them all into an empty file.
You need to check by the date you created your last script. Obviously, it is going to be the last part of your Ipython history.
To write your Ipython history into a file:
%history -g -f anyfilename
On linux:
I did the same error and I finally found the deleted file in the trash
/home/$USER/.local/share/Trash/files
If you deleted it through the OS (rm file.ipynb) then you can probably get it from ~/.ipython_checkpoints/ However, if you deleted it from the browser menu option, it is gone (by design!).
See discussion here: https://github.com/jupyter/notebook/issues/405
If you use PyCharm, you can do the following.
Open the Local History view.
Select the version you want to roll back to.
On the context menu of the selection, choose Revert.
Worked for me!

For the unlucky ones like me, that delete some files on JuliaBox(jupyter for julia), there is a solution. I successifly recovery all my deleted files.
The browsers strore cache information about the pages you visit. You have to find your cache browser folder (in ubuntu with crhome was ~/.cache/google-chrome/Default/Cache) and grep for some text of your notebook in the binarys. Then, cut the text part of the file that is correspond to your ipynb.

If you're using windows, it sends it to the recycle bin, thankfully. Clearly, it's a good idea to make checkpoints.
As long as your Kernel is active, the code of each executed cell is stored in input history list. This will come in handy when you accidentally deleted a cell and want to retrieve its content.
_ih[-10:] *# code of the 10 most recently run cells (Even if those cells are deleted now)*
If you are running on Jupyterlab on linux like me. What I did is went into command prompt and went to my trash folder.
Trash directories on linux are typically
/home/$USER/.local/share/Trash
or
If you deleted something as root (e.g. deleted a file using Nautilus invoked via gksu), it is at
/root/.local/share/Trash
I ended up changing directories to /home/$USER/.local/share/Trash/files and my deleted notebook was there! depending on how you access your backend you could also try /home/jupyter/.local/share/Trash/
ps
If you are having issues changing directories from Trash to files due to permissions dont forget to become root:
sudo -i
then after sudo -i, go up with:
cd ..
and then
cd home/jupyter/.local/share/Trash
cd files
Best of luck,
Sadly my file was neither in the checkpoints directory, nor chromium's cache. Fortunately, I had an ext4 formatted file system and was able to recover my file using extundelete:
Figure out the drive your missing deleted file was stored on:
df /your/deleted/file/diretory/
Switch to a folder located on another you have write access to:
cd /your/alternate/location/
It is proffered to run extundlete on an unmounted partition. Thus, if your deleted file wasn't stored on the same drive as your operating system, it's recommended you unmount the partition of the deleted file (though you may want to ensure extundlete is already installed before proceeding):
sudo umount /dev/sdax
where sdax is the partition returned by your df command earlier
Use extundelete to restore your file:
sudo extundelete --restore-file /your/deleted/file/diretory/delted.file /dev/sdax
If successful your recovered file will be located at:
/your/alternate/location/your/deleted/file/diretory/delted.file
I had the very problem and I ended up solving it this way. It might be the case for some of the folks.
I am working with PyCharm 4.04. Since I installed it, every time I open it, as default directory I get this:
C:\Users\Laura\AppData\Local\Temp\main.py1.tmp>cd
Which gives me an error when trying to use the console:
Error:Cannot start process, the path specified for working directory
is not a directory
But even if I change the directory, the message does not disappear.
The terminal, though, it does work and I can run projects, but I would like to use the console.
Another solution is to close the project, run rm -rf .idea and re-open it. Apparently Pycharm gets confused by some direct folder manipulation and doesn't reflect it properly in his .idea/*.xml files
I also got this error, and it got resolved by setting the default working directory. Follow the below path, and set the Working Directory to the folder where your code resides.
File > Settings > Build, Execution, Deployment > Console > Python Console > Working Directory ...
I finally solved the problem.
I think it all started because the first project that I opened with pycharm was in my "download" folder, so the working directory was automatically set to a temporal folder by default and allthough I moved the project to another folder and I manually changed the working directory from the terminal, it was not working.
The solution was creating a new project and giving a correct path to the new project. It seems very easy but it was not that obvious.
In the upper right corner click on small ▼ next to your main to run (look to the left from green right-pointing triangle)
Select Edit configurations.
In ▼ Python select the proper configuration name.
Look at the Configuration panel.
Fix items Script and Working directory.
pycharm
I had this same problem and just had to reinstall pycharm. It's a quickfix and I can't ensure it won't happen again.
I solved this by replacing all instances of the old filename and old directory with the new one in .idea/workspace.xml
It can be done with PyCharm running.
#user1068430 has the answer in the comments to the question:
When you open a project open the directory not a specific python file.
Instead of ~/Documents/myProject/main.py open ~/Documents/myProject
If you "open" the .py file then you'll have to set the working directory (File > Settings > Build, Execution, Deployment > Console > Python Console > Working Directory) every time. If you "open" the directory containing the .py file, then PyCharm will open and all of your .py files will be available in the left window. Select one of them and you're good to go.
i had the same issue, the error comes up when i want to upgrade my packages and when i run my project "this FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\youruser\AppData\Local\Temp\gen_py\3.7\__init__.py'" i found that the Temp file in C:\Users\youruser\AppData\Local was corrupt and it was fixed by deleting the "Temp" file, once deleted it will automatically create a new one with "gen_py" in it
To anyone with similar issues: Python interpreter virtual environment is where your python.exe sits. The working directory is where your script sits. To make everything easier, open a new project, scroll to location where you script is stored, and select. Click the interpreter option, click existing (if old one worked) or choose the python.exe. When asked, open the project in a new window, close old one to avoid confusion.
source = banging my head against the console for past few hours.
if the above mentioned solutions are not working, you can restart a new project.
file > New project...
then,
create a new project.
