Core Script

Help Commandpihole --help
Script Location/usr/local/bin/pihole
Example Usagepihole -b advertiser.example.com

The core script of Pi-hole provides the ability to tie many DNS related functions into a simple and user-friendly management system, so that one may easily block unwanted content such as advertisem*nts. For both the Command-line Interface (CLI) and Web Interface, we achieve this through the pihole command (this helps minimize code duplication, and allows users to read exactly what's happening using bash scripting). This "wrapper" elevates the current user (whether it be your own user account, or www-data) using sudo, but restricts the elevation to solely what can be called through the wrapper.

Whitelisting, Blacklisting and Regex

Help Commandpihole -w --help, pihole -b --help, pihole --regex --help, pihole --wild --help
Script Location/opt/pihole/list.sh
Example Usagepihole --regex '^example.com$' '.*\.example2.net'

Administrators need to be able to manually add and remove domains for various purposes, and these commands serve that purpose.

See Regex Blocking for more information about using Regex.

Basic Script Process:

  • Each domain is validated using regex (except when using --regex), to ensure invalid domains and IDNs are not added
  • A domain gets added to or removed from the domainlist table in /etc/pihole/gravity.db
  • The DNS server is then reloaded

Debugger

Help CommandN/A
Script Location/opt/pihole/piholeDebug.sh
Example Usagepihole debug

The Pi-hole debugger will attempt to diagnose any issues, and link to an FAQ with instructions as to how an admin can rectify the issue. Once the debugger has finished, the admin has the option to upload the generated log to the Pi-hole developers, who can help with diagnosing and rectifying persistent issues.

Log Flush

Help CommandN/A
Script Location/opt/pihole/piholeLogFlush.sh
Example Usagepihole flush

When invoked manually, this command will allow you to empty Pi-hole's log, which is located at /var/log/pihole/pihole.log. The command also serves to rotate the log daily, if the logrotate application is installed.

Reconfigure

Help CommandN/A
Script Location/etc/.pihole/automated install/basic-install.sh
Example Usagepihole reconfigure

There are times where the administrator will need to repair or reconfigure the Pi-hole installation, which is performed via this command.

Basic Script Process:

  • basic-install.sh will be run
    • Reconfigure will run through the first-time installation prompts, asking for upstream DNS provider, IP protocols, etc
    • Repair will retain your existing settings and will attempt to repair any scripts or dependencies as necessary
  • The rest of basic-install.sh will then run as appropriate

Tail

Help CommandN/A
Script Location/usr/local/bin/pihole
Example Usagepihole tail

Since Pi-hole will log DNS queries by default, using this command to watch the log in real-time can be useful for debugging a problematic site, or even just for sheer curiosities sake.

Admin

Help Commandpihole -a --help
Script Location/opt/pihole/webpage.sh
Example Usagepihole -a -p secretpassword

Detailed information on this is found here.

Chronometer

Help Commandpihole -c --help
Script Location/opt/pihole/chronometer.sh
Example Usagepihole -c -e

Chronometer is a console dashboard of real-time stats, which can be displayed via ssh or on an LCD screen attached directly to your hardware. The script is capable of detecting the size of your screen and adjusting output to try and best suit it.

Gravity

Help CommandN/A
Script Location/opt/pihole/gravity.sh
Example Usagepihole -g

Gravity is one of the most important scripts of Pi-hole. Its main purpose is to retrieve blocklists, and then consolidate them into one unique list for the built-in DNS server to use, but it also serves to complete the process of manual whitelisting, blacklisting and wildcard update. It is run automatically each week, but it can be invoked manually at any time.

Basic Script Process:

  • It will determine Internet connectivity, and give time for pihole-FTL to be resolvable on low-end systems if has just been restarted
  • It extracts all URLs and domains from the adlists table in /etc/pihole/gravity.db
  • It runs through each URL, downloading it if necessary
    • curl checks the servers Last-Modified header to ensure it is getting a newer version
  • It will attempt to parse the file into a domains-only format if necessary
  • Lists are merged, comments removed, sorted uniquely and stored in the gravity table of /etc/pihole/gravity.db
  • Gravity cleans up temporary content and reloads the DNS server

Logging

Help Commandpihole logging --help
Script Location/usr/local/bin/pihole
Example Usagepihole logging off

This command specifies whether the Pi-hole log should be used, by commenting out log-queries within /etc/dnsmasq.d/01-pihole.conf and flushing the log.

Query

Help Commandpihole query --help
Script Location/usr/local/bin/pihole
Example Usagepihole -q -exact -adlist example.domain.com

This command will query your whitelist, blacklist, wildcards and adlists for a specified domain.

Basic Script Process:

  • User-specified options are handled
  • Using idn, it will convert Internationalized domain names into punycode
  • Database at /etc/pihole/gravity.db is queried to return a list of adlists in which the queried domain exists.

Update

Help Commandpihole updatePihole
Script Location/opt/pihole/update.sh
Example Usagepihole -up

Check Pi-hole Core, Web Interface and FTL repositories to determine what upgrades (if any) are required. It will then automatically update and reinstall if necessary.

Basic Script Process:

  • Script determines if updates are available by querying GitHub
  • Updated files are downloaded to the local filesystem using git
  • basic-install.sh is run

Version

Help Commandpihole version
Script Location/opt/pihole/version.sh
Example Usagepihole -v -c

Shows installed versions of Pi-hole, Web Interface & FTL. It also provides options to configure which details will be printed, such as the current version, latest version, hash and subsystem.

Uninstall

Help CommandN/A
Script Location/etc/.pihole/automated install/uninstall.sh
Example Usagepihole uninstall

Uninstall Pi-hole from your system, giving the option to remove each dependency individually.

Status

Help CommandN/A
Script Location/usr/local/bin/pihole
Example Usagepihole status

Display the running status of Pi-hole's DNS and blocking services.

Enable & Disable

Help Commandpihole disable --help
Script Location/usr/local/bin/pihole
Example Usagepihole disable 5m

Toggle Pi-hole's ability to block unwanted domains. The disable option has the option to set a specified time before blocking is automatically re-enabled.

Restart DNS

Help CommandN/A
Script Location/usr/local/bin/pihole
Example Usagepihole restartdns

Restart Pi-hole's DNS service.

Checkout

Help Commandpihole checkout --help
Script Location/opt/pihole/piholeCheckout.sh
Example Usagepihole checkout dev

Switch Pi-hole subsystems to a different GitHub branch. An admin can specify repositories as well as branches.

Pi-hole Web

Help Commandpihole -a --help
Script Location/opt/pihole/webpage.sh
Example Usagepihole -a -p secretpassword

Set options for the Web Interface. This script is used to tie in all Web Interface features which are not already covered by the Core Script.

Password

Help CommandN/A
Script Location/opt/pihole/webpage.sh
Example Usagepihole -a -p secretpassword

Set the Web Interface password. Password can be entered as an option (e.g: pihole -a -p secretpassword), or separately as to not display on the screen (e.g: pihole -a -p).

Teleport

Help CommandN/A
Script LocationN/A
Example Usagepihole -a -t

Script Location/opt/pihole/webpage.sh
Example Usagepihole -a interface local

Specify interface listening behavior for pihole-FTL. When using pihole -a interface all, please ensure you use a firewall to prevent your Pi-hole from becoming an unwitting host to DNS amplification attackers. You may want to consider running Wireguard to grant your mobile devices access to the Pi-hole.
