sudo
apt-get install sudo adduser <user> sudo adduser andreas sudo
User andreas has to relogin for the new group to be enabled for him. To check if you are part of the group sudo use
groups
Modify sudo rights and behavior:
visudo
Set vi as editor for visudo (.bashrc of root, will not work this way for any sudo user without more work)
export SUDO_EDITOR=`which vi`
Using sudo without password:
%sudo ALL=(ALL) NOPASSWD: ALL
Make sure to add this as last line or at least after all lines which do anything like this because otherwise the other rules will be used instead of this one.
Don't put your stuff into the regular sudo file which is shown by visudo. Instead create a file
vi /etc/sudoers.d/custom
and add content like this:
# activate this to allow all commands without password # %sudo ALL=(ALL) NOPASSWD: ALL # command per user which don't need a password, comma seperated andreas ALL=(ALL) NOPASSWD: /usr/sbin/shutdown, /usr/bin/ls
top
The output of top looks uninteresting and is bad to read. This does not have to be that way. Download Media:Top-config.zip to your home directory, unzip it and hope it does not crash/destroy something in your system. I only tested this with Debian 10.
- download to your home directory
- unzip
- call top
top
I just pressed '?' and tried the things they tell you there. Then I zipped the result.
install c++
sudo apt-get install build-essential manpages-dev libstdc++-8-doc
If libstdc++-8-doc does not exist, check for later versions. libstdc++-9-doc ...
