This repository contains

configuration files of programs I use on my copy of arch linux and scripts that allow me to set up a new installation of ach with my configuration. My configuration of the following programs are stored inside this repository:
1. oh-my-zsh
2. vim
3. qutebrowser
4. mutt
5. bashrc (zshrc)
6. i3

List of own commands provided in zshrc

lsPdf list the amount of pages of all pdfs in the current directory, sorted by timestemp
ls | lpdf | sort -V list all pdfs (curr dir) by sizes (decr)
sz source zshrc
vz edit zshrc
ct copy terminal. Does also copy the ssh agent and the current directory.
upw after providing ssh key password once, the currnet terminal and all terminals opend via ct can access the ssh key without the necessity to re-enter the ssh key.
addSshAgent like upw, difference: addSshAgent checks whether the ssh agent has already been added (indifferent on whether successful or unsuccessful)
ttt and other scripts are commands for pushing taks to my task tracker and readings repo. hardcoded path.
catasks cats the first n current tasks to the dunst.
diffdir dir1 dir2 prints list of diffs of directories.

Ranger

For enabling the preview, exeucte the following command once:

ranger --copy-config=scope

SSH

ubuntu: apt install openssh-server
vim /etc/ssh/ssdh_config

PermitRootLogin no
PubkeyAuthentication yes
AuthorizedKeysFile	.ssh/authorized_keys
PasswordAuthentication no
(AuthenticationMethods publickey)
UsePAM no
X11Forwarding yes
X11UseLocalhost no
# x = username placeholder
AllowUsers x

Startup behavior

As I do not always require a gui, need a terminal open if the gui does not work (e.g. xkeyboard error) I disabled auto-launching the gui on startup in grub:

vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="text"#< used to be "quiet splash"
sudo update-grub

For my systemd machines:

sudo systemctl enable multi-user.target --force
sudo systemctl set-default multi-user.target

I put eval $(ssh-agent); ssh-add on top of the startx script for automatically adding ssh agent on startup (shared by all applications started by x).

exec xcompmgr -c -f -n

Notes on stuff being likely to be usable in the future:

notify-send "string" # for sending information (e.g. on git updates, battery power)

Finding out class of application

for e.g. window binding to workspace, For assign [class=..] $workspace10

open application,
open xprop via terminal,
click on the app, class = 2nd vlaue

Remap keys

Old proceeding:

/usr/share/X11/xkb/symbols/ #< change keyboard

    // the following lines contain altered stuff
    key <AC06> {	[	  h,	H,	Left,	Left ]	};
    key <AC07> {	[	  j,	J,	Down,	Down ]	};
    key <AC08> {	[	  k,	K,	Up,	Up ]	};
    key <AC09> {	[	  l,	L,	Right,	Right ]	};

and insert the following into the Xmodmap change .Xmodmap in home dir

.Xmodmap
clear Lock
keycode 66 = ISO_Level3_Shift

execute xmodmap .Xmodmap each time on login.

new proceeding: just be sure to execute xmodmap .Xmodmap, and pull the xmodmap from repo :)

change the refresh rate via xrandr

xrandr -s 1280x1024 -r 645

remove cache

#Remove the uninstalled package files:
sudo paccache -ruk0
# Only keep newest 3 versions per pkg 
sudo paccache -r

backlight

it is in most cases sufficient to add the user to the video group in order to change the backlight settings.

sudo pacman -S acpilight
sudo usermod -a -G video $(whoami)
# then find out which device is to be used (for keyboard) and replace the deivce.

At my macbook xbacklight could not detect any controllable devices, so I changed to acpi backlight which is backwards compatible with xbacklight and works fine for screen and keyboard backlight.

sudo pacman -S acpilight
