Count Lines of Codes With Cloc

Linux Programming

Have you ever had the nead to count the lines of code in a project or a folder? If you did, or want to, cloc is a neat utility that can help with just that.

As per it’s description on the GitHub page, «cloc counts blank lines, comment lines, and physical lines of source code in many programming languages». It displays a summary of file types and counted files, and then it breaks down a list of lines of code per language.

Here’s the output from my bash-config project:

 ~/Git/bash-config $ cloc .
      45 text files.
      43 unique files.                              
       4 files ignored. v 1.80  T=0.29 s (146.6 files/s, 10151.3 lines/s)
Language                      files          blank        comment           code
Bourne Again Shell               38            355            440           1525
Bourne Shell                      2             41             32            276
Markdown                          2             52              0            187

And here’s a view of a more complex project with multiple languages:

     346 text files.
     338 unique files.

How to Migrate Unifi Controller

Linux Networking

Quick instructions on how to migrate a Unifi controller on Linux. Note that it requires SSH access to the AP and a bit of downtime.

a. Logon to your old Unifi controller, go to Settings=>Auto Backup and download a backup

Note: Force a new backup if you have new changes

b. Browse to your AP, write down the IP address

c. Select the AP, go to Config=>Manage Device=>Forget this device and click on Forget (click ok on the alert)

d. Login to the new controller and on the first screen restore the backup you saved on step a

e. Once the controller is back up, SSH into the AP with the default user (ubnt:ubnt or root:ubnt) and run the following command (change [controler_ip] for the IP of your controller)

set-inform http://[controller-ip]:8080/inform

f. On the new controller, under devices, the AP should be showing for ‘adoption’. Click on ADOPT

How to Install and Configure Vim Plug

vim bash Linux

Quick step by step instructions to get you started with the Vim plugin manager vim-plug.

a- Install the vim-plug package (Arch) from the AUR repo

aur/vim-plug 0.10.0-1 [installed] (19) (0.05)
    A vim plugin manager

b. Configure your ~/.vimrc with a section for the new plugins. This is where you will define all the plugins that you want to use. I would also add this section at the top of your file.

" Plugin Manager

call plug#begin('~/.vim/plugged')

" Initialize plugin system
call plug#end()

c. Add a plugin to the plugin section. If you don’t know what to add you can start with vim-illuminate, which highlights multiple instances of the same word that is under the cursor.

call plug#begin('~/.vim/plugged')

"Vim plugin for selectively illuminating other uses of the current word under the cursor
Plug 'RRethy/vim-illuminate'

" Initialize plugin system
call plug#end()

d. Now open a file with vim, or if you already have a file open, source your vimrc with :source ~/.vimrc

e. Now that we have the plugin section and a plugin defined, call vim-plug to install your plugin with :PlugInstall

And that’s it! You are ready to start using your new plugin.

Whenever you want to install a plugin, repeat steps «c» through «e».

Using Latte as a Dock in Kde

KDE Linux

Latte is a great «newish» dock for KDE that can be used as launching/task dock, or even completely replace your plasma panels. The dock is fast stable with a good «feel», and it fully supports plasma widgets.

I myself do not like the Apple like task docks. I prefer using docks for app launching and let my panels do the task management. I was looking for a fast dock for my Arch VM at work, and Latte was one of the best options. The only thing missing was how to remove the task manager option. But luckily I ended up finding a way on my own (which feels more of a bug, but I won’t get into it), and I’m sharing the instructions here.

a. Install latte-dock

$ pacman -Syu latte-dock

b. Start the dock (from the terminal or with Alt+F2)

c. Right click on the dock and click on «Add/Widgets». Add a widget (like the «Audio Volume» widget)

d. Right click on the dock again and click on «Dock/Panel Settings»

e. Remove the «Latte Widget»

F. Now try to drag an application icon (like from /usr/share/applications) to the dock. If that does not work, try opening and closing the «Dock/Panel Settings». It will eventually let you add the application icon (hence why I said it seems like a bug). Once the first application shortcut has been added you can drag more.

Here’s a gif animation of the whole process.

TLDR Instead of MAN

Bash Linux

Here’s a quick way to get quick simplified explanation and usage for commands in Bash with TLDR Pages.

$ tldr tldr
# tldr                                                                            

  Simplified man pages.                                                           

- Get typical usages of a command (hint: this is how you got here!):              

  tldr command       

TLDR pages is community driven and holds common commands for UNIX, Linux, macOS, SunOS and Windows. The amount of commands available is already pretty vast, and users are encouraged to contribute with new pages on their git repo -

You can also access a web/live version of tldr on



pacman -Sy community/tldr

Other distros:

npm install -g tldr


sudo snap install tldr
