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

• 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.

• daemonize start following process as daemon. Similar to nohup > /dev/null in one simple command.

• getlastword get last word of input

• grepx before after wrapper for grep for specifying region around search hit to be displayed

For enabling the preview, exeucte the following command once:

ranger --copy-config=scope 

• 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 

1. 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 

2. 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

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

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

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

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 :)

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

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
