These commands do not take +time to optimize the Git data, since such optimizations scale with the full +size of the repository while these user commands each perform a relatively +small action. + +The `git maintenance` command provides flexibility for how to optimize the +Git repository. + +SUBCOMMANDS +----------- + +run:: + Run one or more maintenance tasks. + +TASKS +----- + +gc:: + Clean up unnecessary files and optimize the local repository. "GC" + stands for "garbage collection," but this task performs many + smaller tasks. This task can be expensive for large repositories, + as it repacks all Git objects into a single pack-file. It can also + be disruptive in some situations, as it deletes stale data. See + linkgit:git-gc[1] for more details on garbage collection in Git. + +OPTIONS +------- +--auto:: + When combined with the `run` subcommand, run maintenance tasks + only if certain thresholds are met. For example, the `gc` task + runs when the number of loose objects exceeds the number stored + in the `gc.auto` config setting, or when the number of pack-files + exceeds the `gc.autoPackLimit` config setting. + +GIT +--- +Part of the linkgit:git[1] suite @@ -167,6 +167,7 @@ int cmd_ls_tree(int argc, const char **argv, const char *prefix);
