I want to list someone 's git commit ,but I don't know the git command formate of since or after

When I execute this git command: git rev-list --since=2015-03-01, it always says

Invalid object name 'usage'.

I don't know the format of since or after. I'm using Java ProcessBuilder to execute the command. Any help appreciated!

The code:

command=new String[] {"git", "rev-list", "--since=2015-06-22", "--pretty=oneline"};
ProcessBuilder processBuilder = new ProcessBuilder(command);`
Solution

  • You are getting an error about usage because you're using arguments that are not valid for rev-list, and git will print a usage summary as a result. The first word it gets back is usage, which it is complaining about.

    $ git rev-list --since=2015-06-22 --pretty=oneline
usage: git rev-list [OPTION] <commit-id>... [ -- paths... ]
  limiting output:
    --max-count=<n>
    --max-age=<epoch>

    ... and so on.

    Based on your current attempt, I gather you are trying to find commits after a certain date, and return them one per line. Since you are using rev-list instead of log, you probably want a list of commit objects, not full log entries.

    The main problem with your command is that rev-list expects a commit ID or other reference as its starting point, and you aren't supplying one. That's easy, just point it to HEAD.

    This will give you the commit IDs from HEAD back to the specified date.

    git rev-list --since=2015-06-22 HEAD

    Or specified in the syntax you are using for Java,

    command=new String[] {"git", "rev-list", "--since=2015-06-22", "HEAD"};
