I had created a Google compute engine (virtual machine) instance with RStudio Server being unaware that RStudio Server is a licensed software. Now, my trial license for RStudio has expired, and I cannot login to my R sessions anymore.
However, I had written some code which I need to recover. How do I download the files?
I have SSH-ed into my virtual machine but cannot find the relevant files or a way to download them.
I had a similar issue and I was able to recover the files by performing the following steps:
SSH to the virtual machine
Once you are in the virtual machine run the following command: cd ../rstudio-user/
Now ls there you will see the file structure you used to see in the RStudio Server interface}
Navigate using cd and ls between the folders to get to the desired file
Once you are in the desired location (where with an ls you can see the files you want to recover) run the following command: pwd
Click on the Engine and go to download file
Enter the full path of the file you want to download, it will be something like: /home/rstudio-user/FILENAME.R
Click on Download
You can do this for each of the files you want to recover.
In case you want to recover a full folder its easier to compress to a zip file and then to download it.
I was working in a jupyter notebook until it froze. It wouldn't save or shut down so I restarted my computer. I launched jupyter notebook from an anaconda prompt, my folder directory opens per usual. When i tried to open the notebook from before, I get an error loading screen that says permission denied: (name of notebook).ipynb. I hit close and the notebook shuts down.
I checked the folder permissions, I have full control. I can create a new ipynb without any issues. I can open other notebooks without any problem in the same folder. I tried to run a trust notebook through the anaconda prompt and it says the notebook is missing.
I need to recover this particular notebook as it has all my work. Help! Any ideas? Thanks in advance.
I work in the anaconda prompt in an environment other than the root, so this answer using sudo chmod doesn't work for me.
I had possibly the same problem. In my case the problem was that jupyter notebook must have crashed or had some problem whilst autosaving.
As a result, in the folder where the notebook is saved there's a temporary file called ".~nameofnotebook.ipynb".
This file didn't show up in jupyter notebook, but only in the explorer. I deleted the notebook file and renamed the temporary file to delete the ".~" prefix. Make sure to save a copy of the notebook file before deleting anything in case your problem is different.
The renamed temporary file opens fine and none of my data was lost.
Change the name of the file and you are good to go bro..
When I create a new project and select to create a new Git repository, or when I try to change the version control system in project options I receive a RStudio error stating "Incorrect function" with a big X and no extra information.
The below link has a similar issue, but their solution of changing the path for git.exe has not helped (i have tried all three paths)
https://support.rstudio.com/hc/en-us/community/posts/200632528-Git-Error-Incorrect-Function
Some extra notes:
RStudio allows me to clone repository to set new working directory
Also git works in bash, so i feel this is an RStudio issue.
I encountered the same error. For me it also had to do with using a network path not a local directory for the project location (as for lewis1211).
Workaround: Map the network drive. E.g. Map your //server/share to some drive, say Z: (using map network drive, if you are using windows). If you set your project up under Z: then, it works.
If you have already chosen "git.exe" in RStudio --> Tools --> Global Options --> Git/SVN, then try to open Rstudio shell and type git init. In my case it showed "Permission denied", and after running as administrator the problem has gone.
This is only a partial answer if it fixes your problem: I reproduced this when trying to use a network path for a project location. When using a local directory no error occurs. Could indeed be an RStudio issue.
Run you R studio as Project administration.
This solves my issue.
SOLVED.
I had the same problem. The Git-RStudio-Connection fails but git is working perfectly in the CMD. When running the git init command in CMD it works and creates a .git folder. But running the git init command in the RStudio terminal fails with a message Warning: unable to access 'C:/Users/%username%/.gitconfig': Permission denied ... fatal: unknown error occured while reading the configuration files.
The Version Control Sytem (VCS) or git-Panel does not appear in RStudio and selecting it in the projects options leads to the same message Error: Unzulässige Function (eng. Error: Incorrect function).
A closer look into the .gitconfig file should give you a new solution approach hopefully without having administration rights. Comparing the installation on the integration worksation with a productive workstation shows, that on the Test-Machine an incomplete .gitconfig file is on C:/Users/%username%/.gitconfig and on the Productive-Machine a complete gitconfig file is on Z:/.gitconfig. By the way, Z is a mapped drive which is linking to the company's user-profile settings (see CMD > echo %HOMEDRIVE%).
According to this analysis there should be multiple possible solution approaches:
(1) delete the corrupt .gitconfig and hope the the system is correctly looking into your profiles directory
(2) complete the .gitconfig file that all necessary information are there. The message fatal: unknown error occured while reading the configuration files could actually be a hint, that the first message access... permission denied is false and the problem lies in the incomplete file.
(3) Be aware that there can be a confusion between ".gitconfig" as FILE and ".gitconfig" as FOLDER. Check this with changing directory with cd to folder and cat to show the file content. It will tell you that you cannot display a folder as file-content.
(4) Change the location of the config file with git config --file FullnameToGitconfig. e.g. git config --file %USERPROFILE%/.gitconfig or git config --file %USERPROFILE%/.gitconfig/gitconfig or git config --file %HOMEDRIVE%/.gitconfig etc.

I need to copy a file from a windows share directory to AIX box.
I am not able to get into windows share directory when i have connected to AIX box.
Can someone please help as which unix commands to use to use to login into windows share directory so that i can copy the file and paste to AIX box
You can copy by using nfsshare. Open nfsshare in windows and mount it in aix.
smbclient (if installed):
$ smbclient //host/share

I installed Hadoop and Created a user named hduser and changes owner of hadoop folder to hduser.
After installing Hadoop i try to execute the hadoop command to check whether it is installed or not but it is giving "hadoop" command not found.
Then i had given execute privilege to hduser on all the files inside hadoop folder include bin folder
But still output is same.
When i am trying the same hadoop command with root as a user its working fine.
I think it is related to unix commands. Please help me out to give my user the privilege to execute hadoop command.
One more thing if i switch to root then hadoop commands works fine.
It is not a problem of privileges. You can still execute hadoop, if you type /usr/local/hadoop/bin/hadoop, right?
The problem is that $PATH is user-specific.
You have to add your $HADOOP_HOME/bin to the $PATH, as hduser, not as root. Login as hduser first (or just type su hduser) and then export PATH=$PATH:/$HADOOP_HOME/bin, as #iamkristian suggests, where $HADOOP_HOME is the directory in which you have placed hadoop (usually /usr/local/hadoop).
I sounds like hadoop isn't in your path. You can test that with
which hadoop
If that gives you command not found the you probably just need to add it to your path. Depending on where you installed hadoop, you need to add this to your ~/.bashrc
export PATH=$PATH:/usr/local/hadoop/bin/
And then reopen your terminal
