I have an image from https://hub.docker.com/r/wtakuo/xv6-env. I pull it with docker pull wtakuo/xv6-env and run it with:
$ docker run -it --rm -v $(pwd):/home/xv6/xv6-riscv wtakuo/xv6-env
After container created and run image on its, I run make qemu but I get this error:
mkfs/mkfs fs.img README user/_cat user/_echo user/_forktest user/_grep user/_init user/_kill user/_ln user/_ls user/_mkdir user/_rm user/_sh user/_stressfs user/_usertests user/_grind user/_wc user/_zombie
fs.img: Permission denied
make: *** [Makefile:137: fs.img] Error 1
I don't know what should be do to fix it.
this is my directory content (with ll command):

I googled for this but not found effectively answer.
I tried
sudo chown -R user1:user1 *
but show this error: fs.img: Permission denied
For this problem, we must use from sudo command.
our user is xv6 and the password is also the same.
after use from it, we see this output:

I am using jenkins in a docker container and would like to start another instance, whenever I try to use docker command like
docker run -t -i ap/dashboard /bin/bash
I get this error:
bash: line 61: docker: command not found
How do I navigate to another container or solve this error?
I can clearly see that the vm creator was able to use the docker command by reading the /root/.ash_history

I tried many docker commands without hope
is it because that I'm already inside the container??
Try with docker run -t -i ap/dashboard /bin/ash.
Maybe your container does not use bash so you should try with /bin/sh which is a symcolic link to the default installed shell processor.
I would like to program the (MB1355C and/or MB1293C) devices from an STM32WB55 Nucleo Pack on my (Ubuntu 18.04.3 LTS) machine - preferably with the convenience of an eclipse based IDE that supports debugging features.

I downloaded an example project called STM32100E-EVAL_USART_IrDA_Transmit and it builds successfully, but I get the following error message when I connect the evaluation board(s) and click on debug to flash the micro controller
ST-Link enumeration failed
Error in initializing ST-Link device.
Reason: (2) ST-Link DLL error.
I get the same error message when I try the above with STM32CubeIDE.
I have tried shifting JP1 as described in section 7.6 of the users manual but to no avail.
A previous question on stack overflow deals with the same error message so I got STM32CubeProgrammer to launch and tried making the changes suggested by #IsaBostan, but the development boards don't seem to be detected
How can I proceed to resolve this problem and program the boards?
Debugging ideas or suggestions are welcome, even if they haven't been tested...
It was just a question of permissions as suggested by KamilCuk
Launching TrueStudio as root and then clicking on debug solved the problem.
This is what worked on my machine:
sudo su
/opt/Atollic_TrueSTUDIO_for_STM32_x86_64_9.3.0/ide/./TrueSTUDIO
STM32CubeIDE's debugger also works when launched as follows on my machine:
sudo su
/opt/st/stm32cubeide_1.1.0/./stm32cubeide
and STM32CubeProgrammer connects to the device straight away when launched as follows:
sudo su
/usr/local/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/./STM32CubeProgrammer
My device shows up under /dev/ttyACM0 with the following permissions:
crw-rw----+ 1 root dialout 166, 0 Dec 28 11:56 ttyACM0
openocd and st-flash were not required.

Can you please help in resolving this above issue..?
I followed instructions of installing Tomcat from this link how-to-install-apache-tomcat-8-on-centos-7
It seems you are the ec2-user, but the directory is owned by tomcatuser and the permissions on the directory do now allow other users or groups to read it.
Try sudo chmod 755 /opt/tomcatfolder/ and then cd into it.
That will add read and execute permissions to the directory.
I have a docker container running Ubuntu Server. I am running Docker for Windows and I have the following version of Docker and Docker Compose respectively installed:
> docker-compose -v
docker-compose version 1.11.2, build f963d76f
> docker -v
Docker version 17.03.1-ce-rc1, build 3476dbf
This is what I have tried so far without success:
// The dojo linked file exists so I've tried to update it as per this answer (http://stackoverflow.com/a/1951752/719427)
> docker exec -it dockeramp_webserver_1 ln -sf /var/www/html/externals/dojo /var/www/html/externals/public_html/js/dojo
ln: failed to create symbolic link '/var/www/html/externals/public_html/js/dojo': No such file or directory
// I have deleted the previous linked file and then I tried to create a new one

Because the error keep saying the directory doesn't exists then I've checked if the error is right or wrong:

They both exists so ... what I am missing here? It's not supported in Windows just yet? I have found the development team added something called mfsymlinks in a previous version than mine.
The command is telling you that /var/www/html/externals/public_html does not exist. You only showed that the /var/www/html/externals/dojo and /var/www/html/public_html/js folders exist. I believe this is a simple typo in your commands.
I was able to connect to my school server via SSH. I had an assignment in which I was supposed to use the touch command to create a new file. Yet it keeps returning permission denied. Others were able to do the same thing. Though why do I keep getting this error?
Below is what was the input from the terminal.

EDIT:
Here is what I see after trying touch today in /home
So to try and create a new document in the root directory you need to be recognised as root. That means using the sudo command.
However for that you would need a password that you may not have. If you do perfect. But in any case I would not recommend adding files to the root directory.
Instead try the following:
cd home
touch today
This should work just fine and answer your question.
Still if you need/want to create today in your root directory try the following
sudo touch today
You will then be prompted for the root password that you can type (if you have it obviously)
In any case I suggest reading this which may be very helpful for you.
I wonder if this was ever truly answered.
If I was looking at it, I would try to see what the system thinks is the home directory of djaneka1, since it may have been setup partway and not completed, leaving stuff owned by root that should have been owned by djaneka1.
If you use the pwd command, and get back the "/" (root) directory there is something wrong with your setup.
The message: Could not chdir to home directory /u/d/j/djaneka1: No such file or directory
tells you it can't find your home directory.
-bash-3.2$ pwd
/
the command "pwd" revealing "/" is just an artifact of the system not being able to find your home directory.
To find what the system thinks is one's home directory,
one can search the file named '/etc/passwd' for one's login name.
I expect this is a possible result if you do that:
$ fgrep 'djaneka1' /etc/passwd
djaneka1:x:1505:1506::/u/d/j/djaneka1:/bin/bash
since it complained that it couldn't find that directory.
This needs to be fixed by someone who has more rights to the system, like root.
there is nothing djaneka1 can do a
