create git repository

• 文档 https://www.atlassian.com/git/tutorials/setting-up-a-repository/git-init

Start using Git on the command line

The most common use case for  git init --bare is to create a remote central repository:$ssh <user>@<host> cd path/above/repo git init --bare my-project.gitor$git init --bare mautic.gitInitializes a new Git repository and copies files from the  <template_directory> into the repository.$git init <directory> --template=<template_directory>$git clone ssh://[e-mail]/path/to/my-project.gitCloning to a specific folder$git clone <repo> <directory>Cloning a specific tag$git clone -branch <tag> <repo>Shallow clone$git clone -depth=1 <repo>clone only the new_feature branch from the remote Git repository.$git clone -branch new_feature git://remoterepository.gitThis means that a repository will be set up with the history of the project that can be pushed and pulled from, but cannot be edited directly.$git clone --bareGit URLs, Git has its own URL syntax which is used to pass remote repository locations to Git commands.Git URL protocols:-SSH$ssh://[user@]host.xz[:port]/path/to/repo.git/$git clone ssh://coober@192.168.0.62/var/workspace/git_respository/mautic.git-GIT$git://host.xz[:port]/path/to/repo.git/- HTTPhttp[s]://host.xz[:port]/path/to/repo.git/
