Help: heads
hg heads [-ac] [-r STARTREV] [REV]...
show current repository heads or show branch heads
With no arguments, show all repository branch heads.
Repository "heads" are changesets with no child changesets. They are where
development generally takes place and are the usual targets for update and
merge operations. Branch heads are changesets that have no child changeset
on the same branch.
If one or more REVs are given, only branch heads on the branches
associated with the specified changesets are shown. This means that you
can use "hg heads foo" to see the heads on a branch named "foo".
If -c/--closed is specified, also show branch heads marked closed (see "hg
commit --close-branch").
If STARTREV is specified, only those heads that are descendants of
STARTREV will be displayed.
If -t/--topo is specified, named branch mechanics will be ignored and only
changesets without children will be shown.
Returns 0 if matching heads are found, 1 if not.
options:
-r --rev STARTREV show only heads which are descendants of STARTREV
-t --topo show topological heads only
-c --closed show normal and closed branch heads
--style STYLE display using template map file
--template TEMPLATE display with template
use "hg -v help heads" to show more info
