bk-repogca - (unknown subject)
NAME
bk repogca − show greatest common ancestor across a
set of repositories
SYNOPSIS
bk repogca [−dspec]
[−5kS] [repo repo ...]
DESCRIPTION
This command will print the latest revision in the current
repository that exists in all of the the remote repositories
either listed on the command line or implied in the parent
pointer[s]. By default, `bk parent` is the remote
repository.
OPTIONS
−dspec Use spec as the specification
for displaying the revision.
−−dspecf=file Like −d
but read the dspec from a file.
−5 A short hand for asking for a spec of
“:MD5KEY:”.
−k A short hand for asking for a spec of
“:KEY:”.
−S In a component in a nested collection, produce
the repo gca of the component instead of the repo gca of the
product.
EXAMPLES
To generate a traditional patch for the changes that exist
only in the local repository:
bk export -tpatch -r`bk repogca`,+ > patch
To throw away all local work that doesn’t exist in a remote repository:
bk undo -a`bk repogca URL`
Warning: This might also throw away some local csets which also exist in the remote repository. That can happen if there are multiple common ancestors on different branches. The ancestor chosen is the one created most recently.
