The "blame" command:
Usage: fossil annotate|blame|praise ?OPTIONS? FILENAME
Output the text of a file with markings to show when each line of the file
was last modified. The version currently checked out is shown by default.
Other versions may be specified using the -r option. The "annotate" command
shows line numbers and omits the username. The "blame" and "praise" commands
show the user who made each check-in.
Reverse Annotations: Normally, these commands look at versions of
FILENAME moving backwards in time back toward the root check-in, and
thus the output shows the most recent change to each line. However,
if the -o|--origin option is used to specify some future check-in
(example: "-o trunk") then these commands show changes moving towards
that alternative origin. Thus using "-o trunk" on an historical version
of the file shows the first time each line in the file was changed or
removed by any subsequent check-in.
--filevers Show file version numbers rather than
-r|--revision VERSION The specific check-in containing the file
-l|--log List all versions analyzed
-n|--limit LIMIT Limit the amount of analysis:
N Up to N versions
Xs As much as possible in X seconds
none No limit
-o|--origin VERSION The origin check-in. By default this is the
root of the repository. Set to "trunk" or
similar for a reverse annotation.
-w|--ignore-all-space Ignore white space when comparing lines
-Z|--ignore-trailing-space Ignore whitespace at line end
