ArchLinux Cheat Sheet

Network configuration

  • List network devices
      # ip link
  • Enabling and disabling network interfaces
      # ip link set <network interface> up
      # ip link set <network interface> down
  • To check the result:
      # ip link show dev <network interface>
  • Start the DHCP service :
      # systemctl start dhcpcd@<network interface>.service
  • Enable DHCP service to be started on bootup:
      # systemctl enable dhcpcd@<network interface>.service
  • Install and start Network File System (NFS) :
      # pacman -S nfs-utils
      # systemctl start nfs-server.service
      # systemctl enable nfs-server.service

Manage packages with pacman

  • Install a new package
      # pacman -S <package name>
  • Update all package
      # pacman -Syu
  • Remove all the cached packages that are not currently installed
      # pacman -Sc
  • Recursively removing orphans packages and their configuration files
      # pacman -Rns $(pacman -Qtdq)

System and service manager : systemd

Arch Linux uses systemd as the init process.

  • List running units
      # systemctl
  • Start a unit immediately
      # systemctl start <unit>
  • Stop a unit immediately
      # systemctl stop <unit>
  • Restart a unit
      # systemctl restart <unit>
  • Reload configuration
      # systemctl reload <unit>
  • Show the status of a unit
      $ systemctl status <unit>
  • Check whether a unit is already enabled or not
      $ systemctl is-enabled <unit>
  • Enable a unit to be started on bootup
      # systemctl enable <unit>
  • Disable a unit to not start during bootup
      # systemctl disable <unit>
  • Check if any systemd services have entered in a failed state
      # systemctl --failed


  • Kernel warning : "intel_rapl : no valid rapl domains found in package 0"

    Create and edit /etc/modprobe.d/blacklist.conf file with :

      blacklist intel_rapl
  • Add an user
      # useradd -m -G users -s /bin/bash <username>
  • Kernel warning : "ACPI : No IRQ available for PCI Interrupt Link [LNKS]. Try pci=noa"
    • Open /boot/grub/grub.cfg

    • In the Arch Linux entry menu, find the line beginning with linux

    • At the end of this line add

    • Example :

      	linux   /vmlinuz-linux root=UUID=a590453b-f844-4cf5-a74f-66a945eb2434 rw  quiet acpi=noirq

    To test this change before on a temporary grub.cfg modification, type e on menu entry in the boot loader to enter in edit mode.

  • Show boot log
      journalctl -b
  • Enable SSH service to be started on bootup:
      systemctl enable sshd.service
