What

tsk bulk — apply a mutation across many tasks at once, selected via filter flags. Dry-run by default; --apply commits.

The current workflow for retagging or repriorititizing more than a couple of tasks is "open in $EDITOR and find/replace" — fine for one task, awful for 20.

Selectors (AND between types, OR within repeats)

At least one selector required.

Mutations

At least one mutation required. --set-due and --clear-due are mutually exclusive.

Behavior

• Default: dry-run. Prints which tasks would change and the mutation summary, then a hint to re-run with --apply.
• --apply: commits the edits and prints updated N task(s): <summary>.
• No matches: prints no tasks matched and exits 0.

Examples

$ tsk bulk --tag old --add-tag legacy --remove-tag old --apply
updated 2 task(s): +tags[legacy], -tags[old]

$ tsk bulk --priority low --status open --set-priority medium
DRY RUN — 5 task(s) would be changed (priority=medium):
  #2    refactor parser
  #4    investigate flaky test
  #9    deps: bump go-cmp
  #11   docs: rewrite quickstart
  #14   triage backlog

re-run with --apply to commit.

Tests

11 new tests in internal/commands/bulk_test.go:

• requires selector
• requires mutation
• dry-run is default; no write
• tag add + remove + filter together
• priority filter + set-priority
• multi---id selection
• --clear-due
• --set-due and --clear-due mutually exclusive
• no-match prints message, exits 0
• tag match is case-insensitive
• --add-tag is idempotent (no duplicate)
