项目历史

The xrdb manual carries Digital Equipment Corporation and Open Group copyright dates from the 1990s and identifies Bob Scheifler and Phil Karlton as authors, rewritten from Jim Gettys's original. That lineage places xrdb in the classic MIT X / X11 tooling family, before the program was maintained as part of the modular X.Org application set.

The tool's design follows the X resource system: resources can be stored in RESOURCE_MANAGER on screen 0 and SCREEN_RESOURCES on individual screens. The X(7) manual describes xrdb as the program used by startup systems such as xdm and xinit to put global and per-screen resources into those properties.

采用历史

xrdb became a normal part of X session startup because many X Toolkit and Xlib-era applications read resources from the server. It is a quiet dependency of the .Xresources/.Xdefaults culture: users could keep one resource file, merge it at login, and have X clients pick up consistent defaults across hosts and screens.

Its adoption persisted through packaging because the resource database remains relevant for traditional X clients, terminal emulators, lightweight window-manager sessions, remote X workflows, and compatibility setups even as many desktop applications moved to toolkit-specific configuration systems.

使用方式

Typical usage is `xrdb -merge ~/.Xresources` from an X startup file, followed by `xrdb -query` to inspect the server-side database. Users also use `-load`, `-override`, `-remove`, and `-edit` when replacing or round-tripping resource settings.

For package users, xrdb is most visible when installing or configuring xterm, bitmap-era X applications, old app-defaults packages, or minimalist desktop sessions where the user wants font, color, cursor, and widget defaults controlled by X resources.

为什么软件包爱好者会关心

xrdb is a classic example of a tiny package with outsized historical surface area: it is not a daemon or library, but it is the bridge between a user's resource files and the X server state that clients consult.

It matters in package catalogs because it explains why X11 setups still ship separate utilities for session glue. Without xrdb, many old-but-still-packaged X applications lose the shared configuration path their manuals assume.
