I just use the answer of
This question and now all the folders in root have different permissions and I can't use some programs like Chromium, terminal, etc.
I just replace dirs_to_modify by /home/my_user/.hidden_folder
Also, I should state that I ran the script as root using sudo.
I feel like I broke my Ubuntu OS.
Help please.

I am new to these forums and to using Ubuntu and linux and UNIX. I really need some help here. I hope I haven't shot myself in the foot already. I have been trying to complete a UNIX carpentry lesson on the internet for an assignment. I am learning the basics about UNIX. I am not using a Mac, I am using a PC that I did not configure in any way (maybe that's my problem). I am using windows 10 on a lenovo and trying to the command prompt on Ubuntu to find my desktop where a file called "data-shell" is located. The problem: IT IS NOT FINDING THE DESKTOP. Upon further inspection, I have been looking through the location of my desktop and "data-shell" file and found it in the Users location under a number 12094, which I am assuming is the serial number for the computer. I have NEVER fiddled with the software at all with this computer as it cost me a lot of money, but I really do not want to be stopped in the tracks already. I have the following images numbered in the order that I discovered everything; they are posted here. I would really appreciate the help. P.S.: Since I am using a PC and not mac, I thought I had to use another command line like BASH or the terminal on my PCor doI just use Ubuntu? The UNIX shell is supposed to start with a $, right? Please correct me if I a wrong and thank you for your help

linux commands on windows can be ran via cmder or git bash (what i had used in past)
and in linux the desktop is at the path
/home/< username>/Desktop
whereas in windows its
C:\Users<username>\Desktop
both windows (DOS) and ubuntu/mac(linux) environment are entirely different you can directly run commands of one on the other environment, you do need to "setup" that env first if the command is not native to that.
Now, since its assignments that you are doing and all you need is bare-min linux env
you can give https://repl.it/ a try and create a new project in bash
Also, when you install Ubuntu on windows you dont get acces to windows like path, like "C:...", in ubuntu c:\ of windows is mounted to some other path in ubuntu
search on google how to access windows desktop from ubuntu shell after installing ubuntu inside of windows
When using Windows Subsystem for Linux (WSL), your C drive is located under /mnt/c.
Judging from the screenshot, you are user 12094, so you can either accept this, or you need to actually configure your machine. Also if you look in the screenshot you provided, there is a /home folder which I am betting is actually pointing to /mnt/c/, and your home folder will be under /home/12094, which is also the same as what is stored in $HOME.
To find the location of a file called data-shell, you can run the following linux command while in your home folder:
find $HOME -type f -name 'data-shell'
This command recursively searches for files in your home directory, with the name data-shell
I have had to install Ubuntu command line on windows10 in order to install R and download a package that is not supported on R for windows. This has worked fine, however, I need to set the working directory in R to the folder containing the files the package needs to work with. I have looked at lots of forums about changing directory and I have no luck!
My default working directory is a hidden folder created by windows when I installed ubuntu command line. I can access this, but I dont need this folder...I need to change the working directory in R to a folder on the D drive on my computer. I have tried to no avail!!
I have tried the normal setwd() command with the following combinations, all of which return the error 'cannot change working directory'
setwd("D:/RNA-seq data/")
setwd("d:/RNA-seq)
setwd("~D:/RNA-seq)
I am really frustrated that I cannot carry out this simple command (maybeI am doing something fundamentally wrong) or maybe this is a limitation because of the hidden default home folder set by windows? Please not I cannot transfer the necessary files in to the default folder created by windows for 'home/R' as it is on the C drive and there isnt enough space on disk. I need to navigate to the folder on d drive in order to carry out my code!!
Any help would be really really appreciated! Many thanks!
I was trying to set a new home directory for Cygwin, but the thing is I've managed to do so only partially.
I changed the 'db_home:' parameter (cygwin64/etc/nsswitch.conf) to '/windows' so it now matches the win10 default home folder, but the trick works only if mintty.exe was run through cmd.
Running mintty manually with a desktop shortcut results with the very same default directory as if the file was never changed.
Having all that said, I'm a total newbie when it comes to both Cygwin and Unix in general, so it's very likely I missed something obvious.
I appreciate any help provided, thanks in advance.
I was using a dual boot system and backing up in Linux my files using rsync and link-dedt and everything was working perfectly. Because the computer is mostly logged in Windows I decided to install cygwin and try to use rsync to do my backups. That way I can have a script that runs automatically every week. However when I tried to continue my backup using link-dest in cygdrive it didn't work. I think is because the files permission are seen differently by cygwin and Linux.
My command was something like:
rsync -av --exclude-from=exclude.txt --progress --link-dest=/cygdrive/e/2016-02-19/ /cygdrive/d/Users/ /cygdrive/e/2016-02-24/
I looked at files that I knew didn't change in the link-dest and source location and everything looks the same except for the file persmission. How can I omit permissions or solve this problem?
Cygwin on windows does cause lots of strange permissions.
If i was backing windows to a linux host, i would use https://acrosync.com/ which is native rsync for windows, unfortunately it does cost money.
We gave up on cygwin rsync partially due to these issues and ended up developing our own windows replication tool http://www.yintersync.net. Its free for non-commercial use.
I have created a folder to the default server at /var/www/default and everything works as expected.
Inside that folder I made a symlink to ~/WebstormProjects/my-project, using the common ln -s.
It worked for a while, and the last time I updated using apt-get, nginx doesn't follow anymore the symbolic link, which gives me a 404 error, not even listing the symlinks as it used to do.
Tried using the disable_symlinks directive, setting it to off, and nothing happened. Also followed the steps in this link and still nothing. Also added myself to the www-data user, nothing.
But if I edit nginx.conf by changing the user directive to my own user and restarting the server does work, but I know that's a very bad practice and some day in the future it will not allow PHP-FPM to work.
So, what can I do to make nginx follow symlinks, without changing the owner of my source directories? BTW, I'm using Ubuntu 14.04.3 and nginx 1.4.6 installed via package manager.
It was just a problem with permissions:
chmod 755 /home
chmod 755 /home/user
Got previous commands from this answer.
