The jj absorb command in Jujutsu (jj), a Git-compatible version control system, moves changes from the working-copy commit into specified target commits. Unlike traditional Git, jj always treats the working copy as a committed state, allowing seamless integration of unstaged modifications.

By default, it absorbs changes into the parent of the working-copy commit (@-), effectively amending the previous commit without a separate staging area. This is ideal for incorporating small fixes or refinements post-commit.

Users can specify --source to select different source revisions and --revision (or -r) for targets. Interactive mode enables hunk-by-hunk selection. It handles multiple revisions, message editing, and unknown files. Dry-run previews actions.

This command streamlines workflows in jj's change-centric model, reducing commit fragmentation while preserving history. It's safer than rebasing for local changes, as jj uses immutable snapshots with operation logs for reversibility.

Requires no conflicts between source and target; may fail on divergent histories. Use jj log to verify revisions. Not for remote changes—use jj rebase.
