kdocker is a utility for the KDE desktop environment that allows users to dock application windows to the taskbar (panel). When docked, windows are minimized but remain accessible via their icon on the panel, behaving like traditional dock applications.

It primarily targets KDE 3.x and 4.x, integrating with KWin window manager. Users can dock the active window without arguments or specify windows by title or class name. Options like --iconic minimize to icon, and --keep prevents undocking.

Common use: Run kdocker to dock the foreground app, freeing desktop space while keeping quick access. It's lightweight but deprecated in modern Plasma (KDE 5+), where Plasma panels and activities handle similar tasks natively.

KDE 3/4 only; unsupported in Plasma 5+. Requires running KDE session. Window must support iconify.

Without args, docks the active/foreground window.

Use xprop | grep WM_CLASS or xwininfo to get window class/title for precise targeting.

Developed for KDE 3.x (~2003) as part of kdeutils or kdocker package. Maintained through KDE 4, but dropped in Plasma 5 favoring native panel features. Last active ~2010.
