If the +repository is specified as a URL, then this flag is ignored (and we +never use the local optimizations). Specifying `--no-local` will +override the default when `/path/to/repo` is given, using the regular +Git transport instead. + +--no-hardlinks:: + Force the cloning process from a repository on a local + filesystem to copy the files under the `.git/objects` + directory instead of using hardlinks. This may be desirable + if you are trying to make a back-up of your repository. + +-s:: +--shared:: + When the repository to clone is on the local machine, + instead of using hard links, automatically setup + `.git/objects/info/alternates` to share the objects + with the source repository. The resulting repository + starts out without any object of its own. ++ +*NOTE*: this is a possibly dangerous operation; do *not* use +it unless you understand what it does. If you clone your +repository using this option and then delete branches (or use any +other Git command that makes any existing commit unreferenced) in the +source repository, some objects may become unreferenced (or dangling). +These objects may be removed by normal Git operations (such as `git commit`) +which automatically call `git gc --auto`. (See linkgit:git-gc[1].) +If these objects are removed and were referenced by the cloned repository, +then the cloned repository will become corrupt. ++ +Note that running `git repack` without the `--local` option in a repository +cloned with `--shared` will copy objects from the source repository into a pack +in the cloned repository, removing the disk space savings of `clone --shared`. +It is safe, however, to run `git gc`, which uses the `--local` option by +default. ++ +If you want to break the dependency of a repository cloned with `--shared` on +its source repository, you can simply run `git repack -a` to copy all +objects from the source repository into a pack in the cloned repository. + +--reference[-if-able] :: + If the reference repository is on the local machine, + automatically setup `.git/objects/info/alternates` to + obtain objects from the reference repository. Using + an already existing repository as an alternate will + require fewer objects to be copied from the repository + being cloned, reducing network and local storage costs. + When using the `--reference-if-able`, a non existing + directory is skipped with a warning instead of aborting + the clone. ++ +*NOTE*: see the NOTE for the `--shared` option, and also the +`--dissociate` option. + +--dissociate:: + Borrow the objects from reference repositories specified + with the `--reference` options only to reduce network + transfer, and stop borrowing from them after a clone is made + by making necessary local copies of borrowed objects. This + option can also be used when cloning locally from a + repository that already borrows objects from another + repository--the new repository will borrow objects from the + same repository, and this option can be used to stop the + borrowing. + +-q:: +--quiet:: + Operate quietly. Progress is not reported to the standard + error stream. + +-v:: +--verbose:: + Run verbosely. Does not affect the reporting of progress status + to the standard error stream. + +--progress:: + Progress status is reported on the standard error stream + by default when it is attached to a terminal, unless `--quiet` + is specified. This flag forces progress status even if the + standard error stream is not directed to a terminal. + +--server-option=
