Smallest Distro To Compile Code
Unix

I am running Windows and I don't have a very big SSD. I want to use Linux in a VM to compile GIMP but I want to keep the VM as small as possible.

What is the smallest distro you can use to compile code? TinyCore is about 15MB but I doubt it includes build-essential.

The GIMP source and compiled binaries are also probably going to be bigger than the distro itself!

How to fully manage users and groups with web GUI?
Unix

I currently have an Ubuntu server with 10-15 users. I have some CLI experience, but I am not a fully CLI ninja. I currently have some groups made in the CLI to manage different groups of users.

In the near future we will probably expend ( how much more is not sure right now). Before things get out of hand I am currently looking for some sort of central managing system to manage the use


flatten the output of recursive directory listing
Unix

Is there a way to list out all the files within a directory tree in a single list, sorted by modification time on Linux?

ls -Rlt 

lists out files recursively, but they are grouped under different folders in the output and as a result, the output isn't sorted as a whole. Only the contents of each directory are sorted by time.

Mount a windows share without having root credentials
Unix

I am trying to mount a Windows shared folder in my home folder. I am able to execute the following command from a Linux (i.e., CentOS) machine which I have sudo access. The command that I am using is:

sudo mount -t cifs //172.17.53.171/Projects ~/RemoteProjects -o
username=domain/mhicks

The real trick is trying to mount the same folder on a machine which I do

What display manager/window manager can support multiple monitors with different dpi?
Unix

There is no permutation that I have yet found of window manager / display manager, that correctly scales windows and applications on two different monitors with two different DPIs.

I have a 40 inch 4k monitor running about 110 dpi, plugged into a hidpi Dell notebook at about 240dpi. I have to accept far too tiny assets on the hidpi or far too large on the big monitor. It just doesn't l


Change in bash prompt depending on whether first character is a space
Unix

Right now every command which starts with a space character gets ignored by bash history (HISTCONTROL=ignoreboth in ~/.bashrc).
I would like to have a better visual cue when I press space as the first character in the prompt input field.

So is there a method of adding such a thing in the bash prompt?
For example, you would color a part of the prompt whe
