如何将所有当前未跟踪的文件/文件夹添加到 git ignore？

Question

I initialized the git repository and made a first commit. Now, in this directory I run ./configure and ./make all so that it populates a lot of extra files/folders don't want to track.

What I would like to do, is to add all those untracked files once and for all to my gitignore. Is there any simple way to do it?

I can get rid of some unnecessary files like *.o or *.mod by specifying appropriate lines in .gitignore, but this does not solve the problem.

Answer 1

Try this:

git status -s | grep -e "^\?\?" | cut -c 4- >> .gitignore

Explanation: git status -s gives you a short version of the status, without headers. The grep takes only lines that start with ?? , ie untracked files, the cut removes the ?? , and the rest adds it to the .gitignore file.

Answer 2

A simpler command to do this is

git ls-files --others --exclude-standard >> .gitignore

You might want to edit the result to replace repeated patterns with wildcards.

Answer 3

如果您的工作树除了未跟踪的文件/文件夹之外是干净的，则可以使用awk更短的解决方案：

git status -s | awk '{print $2}' >> .gitignore

Answer 4

in the accepted answer, the grep part was causing me problem (ie was not filtering, instead all lines including those starting with M (modified) were shown as well), and replacing "^\\?\\?" with "^??" solved it for me. I am on win 10 and using it in msys2's bash.
