when I was try to use touch command on my ubuntu bash shell and in my Desktop folder /mnt/c/Users/Public/Desktop$ it give me this touch: cannot touch 'test.txt': Permission denied error.
You may not have access to the /mnt/c/Users/Public/Desktop directory as default
Run:
ls -ld /c/mnt/Users/Public/Desktop
to see whether you have write permissions as default. If you don't run:
sudo chmod +w /mnt/c/Users/Public/Desktop
This will then allow you write permissions to the directory and allow you to create files.
NOTE - Please ensure that the initial bash executable is run as administrator at Windows level

I am new to linux. I have a build.sh file which consists of a lot of mkdir commands and some rm commands. But as I have installed this new in my VB, each time I run the .sh file, it says "Permission Denied for creating directory" and fails.
So is there any way that I grant directory privileges to all users.
Can anyone help me with this
Add "sudo" in the beginning of the directory creation command i.e
sudo mkdir dir_name
The issue might be with the directory in which the mkdir command is being run.
Use the command ll or ls -l to check the directory permissions.
If your directory doesn't have write privilege for the current user, you can run
chmod -R u+w /path/to/directory
This might require you to use sudo if permission is denied.
If you want to enable it for all users, run
chmod -R ugo+w /path/to/directory
Alternatively, a quick fix would be to run the build.sh file as root
sudo /path/to/build.sh
However, this approach is not advised unless you always run it as root
I am currently working on a bash script which has a user that is created for the job it is running. The user does not exist outside of the script. I am trying to test my code coverage while leaving the user intact.
exec aa-exec -p test-user -- coverage run --source=/test/server ./main.py
The problem is that the test-user does not have access to the code coverage folder. After running chmod -R 777 /usr/local/bin/coverage I still get /usr/bin/python: can't open file '/usr/local/bin/coverage': [Errno 13] Permission denied. I have also tried to temporarily elevate the user inside the bash script using sudo, but because the user only exists inside the file, the sudoers file throws an exception.
I am currently out of ideas since the permissions for this user have to remain restricted ideally. Any suggestions?
Have you checked, that the user has access to each of the directories above?
I.e. the user needs to have 'x' and 'r' rights to each of these directories:
/usr
/usr/local
/usr/local/bin
Linux System: Ubuntu 14.04 LTS
I copy some app (like xxx) to the /opt folder to be used also by another user-accounts. Then to start it I use:
sudo /opt/xxx_folder/xxx
(of course, links to /usr/local/bin or /usr/bin, etc.) to start it;
Problem: I'm storing the results/projects of the app to my local folder ( like /home/myuser/xxx_data). And of course the folder and it's data xxx_data belongs to root (not myuser). So I have to change the owner every time I want to edit those files using another app not as a root.
Question: is there a way to install an app xxx to /opt so, that I don't need to start them as a root?
OR maybe you see another way to solve this 'root-user-problem?'
You can add execute permission to any file like this.
sudo chmod +x file.sh
If you want to do that for all files in that folder try this:
sudo chmod +x /opt/*
Note the +x just adds execute permission to your logged in user. I think all users have read (+r) by default so if you also want to add write permission:
sudo chmod +xw /opt/*
Personally I keep all my custom scripts in a bin folder e.g. /opt/bin/ and just do:
sudo chmod +x /opt/bin/*
To run the script without the full path add the bin or full opt folder to your path by adding the following to ~/bashrc file:
PATH=$PATH:/opt/bin
If you don't end up using the bin folder, edit above to be /opt instead of /opt/bin.
I got this error
sudo: unable to excute ./blah.sh: No such file or directory
my code is every simple
#!/bin/bash
echo "blah"
And I'm sure that I've changed the permission to "rwx". When I try sudo bash blah.sh, I will get the output. But I still cant execute the file. And I'm in debian OS.
Anyone knows why?
make it executable
sudo chmod a+x ./blah.sh
that sets the executable bit for all users just
+x
for your single user
Check in /etc/sudoers if your username is allowed to sudo.
After extracting and saving the ant files into an opt/ directory and setting the path variable
to $ANT_HOME/bin
I ran the following command on a CentOS 5
ant -version
and I am getting the following error
-bash:/path/opt/apache-ant-1.8.2/bin/ant: Permission denied
Is there some permission I am supposed to set or some typical source of this problem?
Thanks!
If you own the file, try
chmod u+x /path/opt/apache-ant-1.8.2/bin/ant
If someone else owns it, either sudo or become root then
chmod 755 /path/opt/apache-ant-1.8.2/bin/ant
You need to have execute permissions on the file; the first gives execute permissions to the owner only and is probably preferable if you own the file and are the only one that uses it. The second requires root privileges and gives execute and read permission to everyone, plus write permission to the owner.
You can view the current permissions and ownership of the file by running ls -l /path/opt/apache-ant-1.8.2/bin/ant.
