git - 是否所有 git 命令都有空运行选项？

Question

是否所有 git 命令都有一个 --dry-run 选项，或者一个可以指示该命令在不实际执行它们的情况下会做什么的选项？

Answer 1

并非每个命令都自然地支持直接试运行。

• git merge 有 its own option (git merge --no-commit --no-ff)
• 但是git pull does not really need it ('git fetch origin', 然后是 'git log master..origin/master'，在 git merge origin/master 之前)
  (但是 git push 有一个试运行选项)

作为J.C. Hamano summarizes :

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.

Another thing to be aware of is that commands like git add and git rm allow the -n command-line option to specify dry run, while in git commit, the -n option means something completely different.
So be sure to check the man page

git commit -n:

-n
--no-verify

This option bypasses the pre-commit and commit-msg hooks. See also githooks(5).
