How to run git commands on remote without having local repo
提问by NickSoft
I have a script called 'git-export' which helps me to export a remote repository. It is run like that:
我有一个名为“git-export”的脚本，它可以帮助我导出远程存储库。它是这样运行的：
git-export http://host.com/git-repo <-t tag or -b branch or -c commit> /local/dir
Before it was used to export local repository and I used these commands:
在用于导出本地存储库之前，我使用了以下命令：
to get commit from branch:
从分支获取提交：
git branch -v --no-abbrev|awk '(=="'$BRANCH'") || ( == "*" && == "'$BRANCH'"){if( == "*"){print ;}else{print ;}}'
or
或者
git rev-parse -q --verify $BRANCH^{commit}
to get commit by tag:
按标签提交：
git rev-parse -q --verify $TAG^{commit}
also I have scripts to list tags, versions (tags, starting with v), I use git branch -v to show branches....
我也有脚本来列出标签、版本（标签，以 v 开头），我使用 git branch -v 来显示分支....
Question is: How can I do these things on remote repository without having local. Is there some general way to query remote. For example: git --remote=http://host.com/repo branch -vor git --remote=http://host.com/repo log
问题是：如何在没有本地存储库的情况下在远程存储库上执行这些操作。有没有一些通用的方法来查询远程。例如：git --remote=http://host.com/repo branch -v或git --remote=http://host.com/repo log
Resion: If I want to install software on remote host I just want to
Resion：如果我想在远程主机上安装软件，我只想
- list versions, branches, etc
- export specific version/branch/commit and show SHA1 of the commit regardless which one of these I export (by export I mean
git archive --remote=<repo>|tar x)
- 列出版本、分支等
- 导出特定版本/分支/提交并显示提交的 SHA1，无论我导出其中哪一个（我的意思是导出
git archive --remote=<repo>|tar x）
edit:
编辑：
I don't want to actionalyl run the commands on remote. I want to use the remote repository with local commands and display it formatted.
我不想在远程操作上运行命令。我想将远程存储库与本地命令一起使用并格式化显示。

You're looking for git ls-remote. For example:
您正在寻找git ls-remote. 例如：
$ git ls-remote git://git.kernel.org/pub/scm/git/git.git

...
(git.git has a lot of tags!)
You can limit yourself to branches with the --headsoption or tags with the --tagsoption, or specify a pattern to select refs, for example to see only the git version tags from git.git, git ls-remote <url> refs/tags/v*. Or you might already know exactly what ref you want: git ls-remote <url> HEAD.
您可以将自己限制在带有--heads选项的分支或带有选项的标签--tags，或者指定一个模式来选择引用，例如只查看来自 git.git, 的 git 版本标签git ls-remote <url> refs/tags/v*。或者你可能已经确切地知道你想要什么 ref: git ls-remote <url> HEAD。
You can't run arbitrary commands on arbitrary remotes, though. The transfer protocols don't support that - they're designed to support listing refs and transferring objects (via packs). In particular, you won't be able to do anything analogous to rev-list. You'll be limited to getting SHA1s for commits pointed to by refs.
但是，您不能在任意遥控器上运行任意命令。传输协议不支持 - 它们旨在支持列出引用和传输对象（通过包）。特别是，您将无法执行类似于rev-list. 您将仅限于为 refs 指向的提交获取 SHA1。

You can use curl for checking if the specific url exists or not for example when i try to hit angularjs existing url
您可以使用 curl 检查特定 url 是否存在，例如当我尝试点击 angularjs 现有 url 时
$ curl -I https://github.com/angular/angularjs.org/tree/master/src
**HTTP/1.1 200 OK**
Server: GitHub.com
Date: Mon, 11 Aug 2014 15:22:40 GMT
When I hit on a wrong URL
当我点击错误的网址时
$ curl -I https://github.com/angular/angularjs.org/tree/master/abcd
**HTTP/1.1 404 Not Found**
Server: GitHub.com
