|

|
|
|
||
|
|
Manage BetterDiscord installations on Linux.
|
||
|
|
|
||
|
|
Options:
|
||
|
|
-V, --version display version info and exit
|
||
|
|
-h, --help display this help message and exit
|
||
|
|
-v, --verbose increase verbosity
|
||
|
|
-q, --quiet decrease verbosity
|
||
|
|
-f, --d-flavors <d_flavors> discover Discord installations with the
|
||
|
|
colon-separated list of suffixes <d_flavors>.
|
||
|
|
Defaults to ':canary:ptb:development'. Flavors
|
||
|
|
must be lowercase. Stable is flavor '', as
|
||
|
|
it's unsuffixed. Flavors shouldn't include
|
||
|
|
spaces.
|
||
|
|
-m, --d-modules <d_modules> use Discord modules in directory <d_modules>.
|
||
|
|
Defaults to discovery. Discord's user-specific
|
||
|
|
storage directory should contain <d_modules>.
|
||
|
|
-D, --bd-remote-dir reference BetterDiscord files at directory
|
||
|
|
<bd_r_dir> <bd_r_dir>. Overrides earlier --bd-remote-url
|
||
|
|
or --bd-remote-github. An empty string keeps a
|
||
|
|
previous value.
|
||
|
|
-U, --bd-remote-url download BetterDiscord files at base URL
|
||
|
|
<bd_r_url> <bd_r_url>. Overrides earlier --bd-remote-dir
|
||
|
|
or --bd-remote-github. An empty string keeps a
|
||
|
|
previous value. Works like --bd-remote-dir
|
||
|
|
with files downloaded into BetterDiscord's
|
||
|
|
data directory.
|
||
|
|
-H, --bd-remote-github download BetterDiscord files at GitHub
|
||
|
|
<bd_r_github> repository release <bd_r_github>, of form
|
||
|
|
[~<owner>][/<repo>][#<release>]. Defaults to
|
||
|
|
'~BetterDiscord/BetterDiscord#latest'. Overrides
|
||
|
|
earlier --bd-remote-dir or --bd-remote-github.
|
||
|
|
An omitted part keeps a previous value.
|
||
|
|
<owner> and <repo> must not contain '~', '/',
|
||
|
|
or '#'. Works like --bd-remote-url with a
|
||
|
|
GitHub repository release download base URL.
|
||
|
|
--bd-remote-asar <bd_r_asar> finds "betterdiscord.asar" at path <bd_r_asar>
|
||
|
|
relative to remote. Defaults to
|
||
|
|
'betterdiscord.asar'.
|
||
|
|
-i, --d-install traditional use a traditional Discord install. Default.
|
||
|
|
-i, --d-install flatpak use a Discord Flatpak app
|
||
|
|
-i, --d-install snap use a Discord Snap app
|
||
|
|
--flatpak-bin <flatpak> invoke Flatpak executable <flatpak>. Defaults
|
||
|
|
to 'flatpak'.
|
||
|
|
--snap-bin <snap> invoke Snap executable <snap>. Defaults to
|
||
|
|
'snap'.
|
||
|
|
--self-upgrade-url query <self_upgrade_url> for self-upgrades
|
||
|
|
<self_upgrade_url>
|
||
|
|
|
||
|
|
Commands:
