What Directory do I use - directory

So I'm looking for the Directory I can use for any computer
Since C:\Users\Cole\Documents\ would only work on my computer what should I replace it with I tried C:\Users\User\Documents\ but it didn't work

You can use C:\ or alternatively PowerShell has the ~ home directory.

Can I use non-canonical share folder paths?

I am working under linux/unix (ubuntu centos darwin)
I often build from source and install my biotools folders in a non-canonical place in order to have full write access to that place for all users and also to avoid overwriting/conflicting with important files placed by the OS in /usr/... and /usr/local/...
I put the tool build folders in /opt/biotools and alias all exe files in /opt/biotools/bin (which is in my PATH)
Now some apps need to access dependencies or libraries usually written in /usr/local/share or /usr/local/lib, ...
Is it possible to add such folders like /opt/biotools/share, /opt/biotools/lib, ... and have the system find them?
Should I add these folders to the PATH?
Thanks for your help

How to change working directory in Julia Jupyter?

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)

user home not the same as "~" in R?

When I call Sys.getenv("HOME") is c:/users/paull/OneDrive/Documents
However, when I go into the command prompt I get
echo $USERPROFILE
C:/users/paull
(using cygwin)
simlarly using command prompt, I have
echo %USERPROFILE%
C:/users/paull
So it seems that R's user home is not actually my users home directory.
Anyone know where this strange behavior is coming from?
I don't use R, but in other languages normally "~" doesn't refer to the working directory but the $HOME directory.
The working directory is assumed if you don't prepend anything.
So try: scan("wgaca/data_dir.txt")

Intro. Unix: Changing Directories

I started an online Unix course. I entered the course kinda late and I'm having a little trouble getting caught up. We had a homework question (I got it wrong) it said to:
Change the current working directory to directory WT5 using a single command line and starting at the home path.
How in the world am I supposed to do that? I know how to change a directory from your current directory just $ cd WT5 And if I wanted to list all of the contents in the home directory I would use $ ls ~/nameofhomedirectory And, if I wanted to change the current working directory to the home directory I would use $ cd ~ or just $ cd
So how would I combine all of that in one single command line to change the current directory to another directory using a path that includes the home directory?
Thank you for all of your help in advance!
UPDATE: Okay. I can see now that this maybe a little confusing. So let me try to make it a little bit more clear where I am going wrong or getting mixed up.
Let's say this is a tree of directories you have.
Tree of Directories
Now, your home directory is user And your current working directory is work But you want to change your current working directory to play. How would you change the directory using a single command line and starting at your home direcotry and not your current working directory work
Thanks again!
I'm not quite sure I understand your question, but you could try:
cd ~/WT5
or:
cd $HOME/WT5
or if you absolutely need to be long-winded about it:
cd /user/homedirectory/subdirectory/currentworkingdirectory/WT5
These all include your home directory in the path. The short-hands are to be preferred.
This might do the trick:
cd ~/../users/carol/play
The idea is that you can go upwards from a home directory too.
