On Docker's documentation pages, all example commands are shown without sudo, like this one:
docker ps
On Ubuntu, the binary is called docker.io. It also does not work without sudo:
sudo docker.io ps
How can I configure Docker so that I don't need to prefix every Docker command with sudo?
How do I save the output of a command to a file?
Is there a way without using any software? I would like to know how.
I am trying to copy the contents of a folder to another folder in a different directory using terminal.
Would somebody be able to provide me an example of the command line syntax required to achieve this?
I get this error when trying to use apt-get:
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?
How can I fix this?
Is there a simple command to display the total aggregate size (disk usage) of all files in a directory (folder)?
I have tried these, and they don't do what I want:
ls -l, which only displays the size of the individual files in a directory, nor df -h, which only displays the free and used space on my disks.
