HOSTS
- Using
Unified hosts + fakenews + gambling
wget -O '/tmp/hosts-tmp' 'https://raw.githubusercontent.com/StevenBlack/hosts/master/alternates/fakenews-gambling/hosts' && sudo cp '/etc/hosts' '/etc/hosts-bak' && sudo mv '/tmp/hosts-tmp' '/etc/hosts' && sync
cat '/etc/hosts' | grep 'Date:'
sudo -e '/etc/hosts'
RoE LAN
- This adds RoE sites to HOSTS file and allows resources to be grabbed over LAN
- Useful for doing significant configurations with sites on LAN
echo -e '\n# RoE LAN\n192.168.1.153 realmofespionage.xyz\n192.168.1.153 social.realmofespionage.xyz\n192.168.1.153 blog.realmofespionage.xyz\n192.168.1.153 media.realmofespionage.xyz\n192.168.1.153 wiki.realmofespionage.xyz' | sudo tee --append '/etc/hosts' > '/dev/null' && cat '/etc/hosts' | grep 'realmofespionage.xyz'
DNF
- Disables Delta RPMs with
deltarpm=false
cat '/etc/dnf/dnf.conf' | grep 'deltarpm=false' || echo 'deltarpm=false' | sudo tee --append '/etc/dnf/dnf.conf' > '/dev/null' && cat '/etc/dnf/dnf.conf'
Repositories
su
- Useful for fresh installations where repo(s) can be added, and then package updates can be ran afterwards unattended without having
sudo
timeout and re-prompt for the password
sudo su

Clean EFI Variables
- Could potentially cause a firmware brick or other issues with improper EFI implementations, use at own risk 7)

Backlight
Notes
- The following commands with an asterisk expect only one backlight controller at
/sys/class/backlight
- This was only tested on one laptop with
intel_backlight
- See Power Management notes on how to add backlight changes to a udev script
- See backlight for more details
Controller Name
ls '/sys/class/backlight'
Query Current Brightness
cat '/sys/class/backlight/'*'/brightness'
Query Max Brightness
cat '/sys/class/backlight/'*'/max_brightness'
Set Custom Brightness
- Change
376
to desired brightness - Desired brightness must be under
max_brightness
value
echo "376" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
Set Max Brightness
echo "$(cat '/sys/class/backlight/'*'/max_brightness')" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
