|
|
'%prog' compares the working tree to the staging area (aka index),
|
|
and the most recent commit on this branch (HEAD), in each project
|
|
specified. A summary is displayed, one line per file where there
|
|
is a difference between these three states.
|
|
|
|
The -j/--jobs option can be used to run multiple status queries
|
|
in parallel.
|
|
|
|
Status Display
|
|
--------------
|
|
|
|
The status display is organized into three columns of information,
|
|
for example if the file 'subcmds/status.py' is modified in the
|
|
project 'repo' on branch 'devwork':
|
|
|
|
project repo/ branch devwork
|
|
-m subcmds/status.py
|
|
|
|
The first column explains how the staging area (index) differs from
|
|
the last commit (HEAD). Its values are always displayed in upper
|
|
case and have the following meanings:
|
|
|
|
-: no difference
|
|
A: added (not in HEAD, in index )
|
|
M: modified ( in HEAD, in index, different content )
|
|
D: deleted ( in HEAD, not in index )
|
|
R: renamed (not in HEAD, in index, path changed )
|
|
C: copied (not in HEAD, in index, copied from another)
|
|
T: mode changed ( in HEAD, in index, same content )
|
|
U: unmerged; conflict resolution required
|
|
|
|
The second column explains how the working directory differs from
|
|
the index. Its values are always displayed in lower case and have
|
|
the following meanings:
|
|
|
|
-: new / unknown (not in index, in work tree )
|
|
m: modified ( in index, in work tree, modified )
|
|
d: deleted ( in index, not in work tree )
|
|
|
|
