jj-run(1) General Commands Manual jj-run(1)

jj-run - Run a command across a set of revisions.

jj run [-r|--revision] [-R|--repository] [--ignore-working-copy] [-j|--jobs] [--no-integrate-operation] [--ignore-immutable] [--root] [--at-operation] [--clean] [--debug] [--restore-descendants] [--color] [--quiet] [--no-pager] [--config] [--config-file] [-h|--help] <COMMAND> [ARGS]

Run a command across a set of revisions.

Checks out each revision in an isolated working copy, runs the command, then amends the revision with the resulting working copy. By default, descendants are rebased on top of the amended revisions, propagating the diff. Use `--restore-descendants` to keep descendants' content unchanged instead.

The command is executed with the following environment variables set:

- JJ_CHANGE_ID - JJ_COMMIT_ID - JJ_WORKSPACE_ROOT

# Example

```shell # Run pre-commit on your local work $ jj run -j 4 -- pre-commit run .github/pre-commit.yaml ```

The revisions to change
How many processes should run in parallel

Overrides the `run.jobs` config setting. Defaults to 1 if neither is set.

Run the command from the working-copy root in each commit instead of from the subdirectory `jj run` was invoked from
Delete each working copy before running the command

By default `jj run` reuses working copies between invocations so build artifacts are preserved. With `--clean`, every commit starts from a freshly checked-out tree.

Preserve the content (not the diff) when rebasing descendants
Print help (see a summary with '-h')
<COMMAND>
Command to run across all selected revisions
[ARGS]
Arguments to pass to the command

Hint: Use a `--` separator to allow passing arguments starting with `-`. For example `jj run --revisions=... -- cargo build --release`.

Path to repository to operate on

By default, Jujutsu searches for the closest .jj/ directory in an ancestor of the current working directory.

Don't snapshot the working copy, and don't update it

By default, Jujutsu snapshots the working copy at the beginning of every command. The working copy is also updated at the end of the command, if the command modified the working-copy commit (`@`). If you want to avoid snapshotting the working copy and instead see a possibly stale working-copy commit, you can use `--ignore-working-copy`. This may be useful e.g. in a command prompt, especially if you have another process that commits the working copy.

Loading the repository at a specific operation with `--at-operation` implies `--ignore-working-copy`.

Run the command as usual but don't integrate any operations

When this option is given, the operations will still be created as usual but they will not be integrated to the operation log. The working copy will also not be updated.

The command will print the resulting operation ID. You can pass that to e.g. `jj --at-op` to inspect the resulting repo state, or you can pass it to `jj op restore` to restore the repo to that state. You can also pass the ID to `jj op integrate` to integrate the operation.

Note that this does *not* prevent side effects outside the repo. For example, `jj git push --no-integrate-operation` will still perform the push.

Allow rewriting immutable commits

By default, Jujutsu prevents rewriting commits in the configured set of immutable commits. This option disables that check and lets you rewrite any commit but the root commit.

This option only affects the check. It does not affect the `immutable_heads()` revset or the `immutable` template keyword.

Operation to load the repo at

Operation to load the repo at. By default, Jujutsu loads the repo at the most recent operation, or at the merge of the divergent operations if any.

You can use `--at-op=<operation ID>` to see what the repo looked like at an earlier operation. For example `jj --at-op=<operation ID> st` will show you what `jj st` would have shown you when the given operation had just finished. `--at-op=@` is pretty much the same as the default except that divergent operations will never be merged.

Use `jj op log` to find the operation ID you want. Any unambiguous prefix of the operation ID is enough.

When loading the repo at an earlier operation, the working copy will be ignored, as if `--ignore-working-copy` had been specified.

It is possible to run mutating commands when loading the repo at an earlier operation. Doing that is equivalent to having run concurrent commands starting at the earlier operation. There's rarely a reason to do that, but it is possible.

Enable debug logging
When to colorize output

Possible values:

  • always
  • never
  • debug
  • auto
Silence non-primary command output

For example, `jj file list` will still list files, but it won't tell you if the working copy was snapshotted or if descendants were rebased.

Warnings and errors will still be printed.

Disable the pager
Additional configuration options (can be repeated)

The name should be specified as TOML dotted keys. The value should be specified as a TOML expression. If string value isn't enclosed by any TOML constructs (such as array notation), quotes can be omitted.
