Presumably, Git will > do 1,000 commits of work when it may only need to do 1 or 5 or 10? The trick is to pipe 'git log' output into another process that reads no more than it needs and exits. Then 'git log' dies from SIGPIPE before it processed all 1000 commits because its down-stream has gone away. For example: git log --show-notes=p4notes -1000 | sed -n -e '/^commit /h' -e '/P4@/{H;g;p;q}' (The pipeline keeps track of the most recent 'commit' line, and when it finds the 'P4@' it prints the most recent 'commit' line followed by the 'P4@' line.) -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
