# Branch Display
The branch display output by this command is organized into four
columns of information; for example:
*P nocolor | in repo
repo2 |
The first column contains a * if the branch is the currently
checked out branch in any of the specified projects, or a blank
if no project has the branch checked out.
The second column contains either blank, p or P, depending upon
the upload status of the branch.
(blank): branch not yet published by repo upload
P: all commits were published by repo upload
p: only some commits were published by repo upload
The third column contains the branch name.
The fourth column (after the | separator) lists the projects that
the branch appears in, or does not appear in. If no project list
is shown, then the branch appears in all projects.
