gwz forall

Run a command in each selected workspace target.

gwz forall [OPTIONS] [projects]... [-- <cmd>...]

gwz forall resolves selected materialized targets, then runs the requested command in each target directory. Positional projects are target selectors: member ids, member paths, or reserved selectors such as @root. When no projects are supplied, the command runs in materialized configured members; the workspace root is included only when selected, for example with --all or @root.

Arguments And Options

Item	Meaning
[projects]...	Target selectors. Empty means the command default: materialized configured members.
[cmd]...	Command and args, run directly without a shell. Use after --.
-c, --command-string <string>	Run a shell command string.
--no-banner	Suppress the per-member banner.

Examples

Run direct argv:

gwz forall -- git status --short

Run a shell command string:

gwz forall -c 'printf "%s\n" "$GWZ_MEMBER_PATH"'

Run in selected members:

gwz forall gwz-cli taut -- cargo test

Run in the workspace root:

gwz forall @root -- git status --short

Run everywhere except the workspace root:

gwz --all --no-target @root forall -- git status --short

Suppress banners:

gwz forall --no-banner -- git rev-parse --short HEAD

Continue after a member command fails:

gwz --partial forall -- cargo test

Use member path substitution in argv mode:

gwz forall -- printf '%s\n' '{@}'

Environment

Each child process receives:

Variable	Meaning
GWZ_MEMBER_ID	Member id.
GWZ_MEMBER_PATH	Workspace-relative member path.
GWZ_MEMBER_ABSPATH	Absolute member path.
GWZ_ROOT	Absolute workspace root.
GWZ_TARGET_KIND	root for @root, otherwise member.

Output And Failure

• Child stdio is inherited and streams live.
• Unless --no-banner is supplied, a === <path> === banner is written to stderr before each member command.
• The command stops on the first failing member unless global --partial is supplied.
• --json and --jsonl are rejected for forall; child output is not wrapped in machine records.
