Command-line arguments

ASF includes support for several command-line arguments that can affect the program runtime. Those can be used by advanced users in order to specify how program should run. In comparison with default way of ASF.json configuration file, command-line arguments are used for core initialization (e.g. --path), platform-specific settings (e.g. --system-required) or sensitive data (e.g. --cryptkey).

Usage

Usage depends on your OS and ASF flavour.

Generic:

dotnet ArchiSteamFarm.dll --argument --otherOne

Windows:

.\ArchiSteamFarm.exe --argument --otherOne

Linux/macOS:

./ArchiSteamFarm --argument --otherOne

Command-line arguments are also supported in generic helper scripts such as ArchiSteamFarm.cmd or ArchiSteamFarm.sh. In addition to that, you can also use ASF_ARGS environment property, like stated in our management and docker sections.

If your argument includes spaces, don't forget to quote it. Those two are wrong:

./ArchiSteamFarm --path /home/archi/My Downloads/ASF # Bad!
./ArchiSteamFarm --path=/home/archi/My Downloads/ASF # Bad!

However, those two are completely fine:

./ArchiSteamFarm --path "/home/archi/My Downloads/ASF" # OK
./ArchiSteamFarm "--path=/home/archi/My Downloads/ASF" # OK

Arguments

--cryptkey <key> or --cryptkey=<key> - will start ASF with custom cryptographic key of <key> value. This option affects security and will cause ASF to use your custom provided <key> key instead of default one hardcoded into the executable. Since this property affects default encryption key (for encrypting purposes) as well as salt (for hashing purposes), keep in mind that everything encrypted/hashed with this key will require it to be passed on each ASF run.

There is no requirement on <key> length or characters, but for security reasons we recommend to pick long enough passphrase made out of e.g. random 32 characters, for example by using tr -dc A-Za-z0-9 < /dev/urandom | head -c 32; echo command on Linux.

It's nice to mention that there are also two other ways to provide this detail: --cryptkey-file and --input-cryptkey.

Due to the nature of this property, it's also possible to set cryptkey by declaring ASF_CRYPTKEY environment variable, which may be more appropriate for people that would want to avoid sensitive details in the process arguments.

--cryptkey-file <path> or --cryptkey-file=<path> - will start ASF with custom cryptographic key read from <path> file. This serves the same purpose as --cryptkey <key> explained above, only the mechanism differs, as this property will read <key> from provided <path> instead. If you're using this together with --path, consider the fact that relative path will be different depending on the order of arguments, i.e. whether you switch --path before or after --cryptkey-file.

Due to the nature of this property, it's also possible to set cryptkey file by declaring ASF_CRYPTKEY_FILE environment variable, which may be more appropriate for people that would want to avoid sensitive details in the process arguments.

--ignore-unsupported-environment - will cause ASF to ignore problems related to running in unsupported environment, which normally is signalized with an error and a forced exit. Unsupported environment includes for example running win-x64 OS-specific build on linux-x64. While this flag will allow ASF to attempt running in such scenarios, be advised that we do not support those officially and you're forcing ASF to do it entirely at your own risk. It's important to point out that all of the unsupported environment scenarios can be corrected. We strongly recommend to fix the outstanding problems instead of declaring this argument.

--input-cryptkey - will make ASF ask about the --cryptkey during startup. This option might be useful for you if instead of providing cryptkey, whether in environment variables or a file, you'd prefer to not have it saved anywhere and instead input it manually on each ASF run.

--minimized - will make ASF console window minimize shortly after start. Useful mainly in auto-start scenarios, but can also be used outside of those. This option requires appropriate environment support - it may not work properly in all possible scenarios.

--network-group <group> or --network-group=<group> - will cause ASF to init its limiters with a custom network group of <group> value. This option affects running ASF in multiple instances by signalizing that given instance is dependent only on instances sharing the same network group, and independent of the rest. Typically you want to use this property only if you're routing ASF requests through custom mechanism (e.g. different IP addresses) and you want to set networking groups yourself, without relying on ASF to do it automatically (which currently includes taking into account WebProxy only). Keep in mind that when using a custom network group, this is unique identifier within the local machine, and ASF will not take into account any other details, such as WebProxy value, allowing you to e.g. start two instances with different WebProxy values which are still dependent on each other.

Due to the nature of this property, it's also possible to set the value by declaring ASF_NETWORK_GROUP environment variable, which may be more appropriate for people that would want to avoid sensitive details in the process arguments.

--no-config-migrate - by default ASF will automatically migrate your config files to latest syntax. Migration includes conversion of deprecated properties into latest ones, removing properties with default values (as they have no effect), as well as cleaning up the file in general (correcting indentation and likewise). This is almost always a good idea, but you might have a particular situation where you'd prefer ASF to never overwrite the config files automatically. For example, you might want to chmod 400 your config files (read permission for the owner only) or put chattr +i over them, in result denying write access for everyone, e.g. as a security measure. Usually we recommend to keep the config migration enabled, but if you have a particular reason for disabling it and would instead prefer ASF to not do that, you can use this switch for achieving that purpose. Keep in mind however, that providing correct settings to ASF will become from now on your new responsibility, especially in regards to deprecations and refactors of properties in future ASF versions.

--no-config-watch - by default ASF sets up a FileSystemWatcher over your config directory in order to listen for events related to file changes, so it can interactively adapt to them. For example, this includes stopping bots on config deletion, restarting bot on config being changed, or loading keys into BGR once you drop them into the config directory. This switch allows you to disable such behaviour, which will cause ASF to completely ignore all the changes in config directory, requiring from you to do such actions manually, if deemed appropriate (which usually means restarting the process). We recommend to keep the config events enabled, but if you have a particular reason for disabling them and would instead prefer ASF to not do that, you can use this switch for achieving that purpose.

--no-restart - this switch is mainly used by our docker containers and forces AutoRestart of false. Unless you have a particular need, you should instead configure AutoRestart property directly in your config. This switch is here so our docker script won't need to touch your global config in order to adapt it to its own environment. Of course, if you're running ASF inside a script, you may also make use of this switch (otherwise you're better with global config property).

--no-steam-parental-generation - by default ASF will automatically attempt to generate Steam parental PINs, as described in SteamParentalCode configuration property. However, since that might require excessive amount of OS resources, this switch allows you to disable that behaviour, which will result in ASF skipping auto-generation and go straight to asking user for PIN instead, which is what would normally happen only if the auto-generation has failed. Usually we recommend to keep the generation enabled, but if you have a particular reason for disabling it and would instead prefer ASF to not do that, you can use this switch for achieving that purpose.

--path <path> or --path=<path> - ASF always navigates to its own directory on startup. By specifying this argument, ASF will navigate to given directory after initialization, which allows you to use custom path for various application parts (including config, logs, plugins and www directories, as well as NLog.config file), without a need of duplicating binary in the same place. It may come especially useful if you'd like to separate binary from actual config, as it's done in Linux-like packaging - this way you can use one (up-to-date) binary with several different setups. The path can be either relative according to current place of ASF binary, or absolute. Keep in mind that this command points to new "ASF home" - the directory that has the same structure as original ASF, with config directory inside, see below example for explanation.

Due to the nature of this property, it's also possible to set expected path by declaring ASF_PATH environment variable, which may be more appropriate for people that would want to avoid sensitive details in the process arguments.

If you're considering using this command-line argument for running multiple instances of ASF, we recommend reading our management page on this manner.

Examples:

dotnet /opt/ASF/ArchiSteamFarm.dll --path /opt/TargetDirectory # Absolute path
dotnet /opt/ASF/ArchiSteamFarm.dll --path ../TargetDirectory # Relative path works as well
ASF_PATH=/opt/TargetDirectory dotnet /opt/ASF/ArchiSteamFarm.dll # Same as env variable

--service - this switch is mainly used by our systemd service and forces Headless of true. Unless you have a particular need, you should instead configure Headless property directly in your config. This switch is here so our systemd service won't need to touch your global config in order to adapt it to its own environment. Of course, if you have a similar need then you may also make use of this switch (otherwise you're better with global config property).

--system-required - declaring this switch will cause ASF to try signalizing the OS that the process requires system to be up and running for its entire lifetime. Currently this switch has effect only on Windows machines where it'll forbid your system from going into sleep mode as long as the process is running. This can be proven especially useful when farming on your PC or laptop during night, as ASF will be able to keep your system awake while it's running.
