Do all git commands have a dry-run option?
提问by vfclists
Do all git commands have a --dry-run option, or one which would indicate what the command would do without actually doing them?
是否所有 git 命令都有一个 --dry-run 选项，或者一个可以指示命令在不实际执行的情况下会做什么的选项？
采纳答案by VonC
Not every command would naturally support a dry run directly.
并非每个命令都会自然地直接支持试运行。
- git merge has its own option(
git merge --no-commit --no-ff) - but git pull does not really need it('
git fetch origin', then a 'git log master..origin/master', before agit merge origin/master)
(butgit pushhas a dry-run option)
- git merge 有它自己的选项(
git merge --no-commit --no-ff) - 但git pull 并不真正需要它（'
git fetch origin'，然后是 'git log master..origin/master'，在 a 之前git merge origin/master）
（但git push有一个空运行选项）
There are things that are not implemented in git because they do not make sense, and there are things that are not implemented in git because nobody had itch to scratch for.
To put it differently, we tend to implement only things that there are actual, demonstrated needs for from real world and only when the addition makes sense as a coherent part of the system.
有些东西没有在 git 中实现，因为它们没有意义，有些东西没有在 git 中实现，因为没有人想要抓挠。
换句话说，我们倾向于只实现现实世界中存在实际的、已证明的需求，并且只有当添加作为系统的一个连贯部分有意义时。

Another thing to be aware of is that commands like
git addandgit rmallow the-ncommand-line option to specify dry run, while ingit commit, the-noption means something completely different.
So be sure to check the man page
另一件要注意的事情是，像
git add并git rm允许-n命令行选项指定试运行的命令，而在 中git commit，该-n选项意味着完全不同的东西。
所以一定要检查手册页
git commit -n:
git commit -n：
-n
--no-verify
This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).
此选项绕过 pre-commit 和 commit-msg 挂钩。另请参阅githooks(5)。
回答by Amber
While there isn't always a --dry-runflag for every comment, there are usually equivalents. For example, this previous questionshows what to do for git merge.
虽然并非--dry-run每条评论总是有一个标志，但通常有等价物。例如，上一个问题显示了要为git merge.
