[ -fl ] [ -fx ] { [ -Fx ] -l <list-file> | <element-list> }The mergelist command determines which element versions must be promoted from one stream (the “source” or “from” stream) to another stream (the “destination” or “to” stream) in order to fulfill this synchronization requirement: after the promotions, all changes recorded in the source stream will have been propagated to the destination stream.Note: for some elements, a merge may be required before such a promotion can occur; for other elements, the version in the source stream can be promoted to the destination stream immediately, without requiring a merge first.mergelist merely provides information. It does not perform any actual merge or promote commands. This command is the “engine” used by the GUI’s Send to Change Palette command to populate the Change Palette with a list of versions to be merged/promoted.Typically, you invoke mergelist on two non-workspace streams. But the command works for any two streams. A case that’s particularly informative is determining which versions need to be promoted from a workspace stream to its own backing stream:This command lists all the versions that are active in the workspace stream gizmo_3.4_john — that is, the members of the workspace stream’s default group. By definition, the default group records the set of workspace-stream versions that have not yet been promoted to the backing stream.mergelist works on an element-by-element basis. For each element in the source stream, it considers the relationship between:Note: non-workspace streams contain virtual versions of elements. Each virtual version is associated with (is a reference to) some real version of the element, which was created in some workspace stream.The derivation can be either direct (a series of keep commands) or indirect (one or more merge commands, along with keep commands). Note that patch commands don’t count in this analysis of a version’s derivation.The mergelist command is quite similar to the form of the diff command that shows the differences between two streams:
