This is a Linux 2.6 kernel repository. I git clone it to my local host.

After that. I didn't make any change. But when I "git status". I found 13 modified files. I want to discard them, but I can't.

A git reset --hard HEAD should solve the problem.

By entering these commands in succession.

git stash
git stash drop

git stash stores modified files on a stack for later retrieval.

git stash drop discards them.

You can use:

git checkout .

To understand the difference between git checkout and git reset refer to the following question :

What's the difference between "git reset" and "git checkout"?

It happens because the linux kernel includes files with the same name (but different cases):

include/linux/netfilter/xt_connmark.h 
include/linux/netfilter/xt_CONNMARK.h

To restore:

modified: specific_filename

git checkout <specific_filename>

It's safer than removing all files at once using git checkout ..

this problem was caused, for me, by a non-case-sensitive filesystem (e.g. on Mac OS). You can either create a case-sensitive disk image and mount it and do your git work on there, or use a different OS to do your development.

You can remove untracked files with clean as well

git clean -f

The question is similar to Strange behaviour of Git: mysterious changes cannot be undone

You need a case-insensitive filesystem. If your PC is Apple MAC like me, you can create Case-sensitive disk.

hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 25g ~/android.dmg

hdiutil resize -size <new-size-you-want>g ~/android.dmg.sparseimage

# mount the android file image
function mountAndroid { hdiutil attach ~/android.dmg.sparseimage -mountpoint /Volumes/android; }

# unmount the android file image
function umountAndroid() { hdiutil detach /Volumes/android; }

There's another possibility where the issue is filemode-related. In that case you may try git config core.filemode false

More info: How do I make Git ignore file mode (chmod) changes?

Edit:

Another possibility would be the line endings, try setting git config core.autocrlf true|false|input and see if it makes any difference.

More info: Why should I use core.autocrlf=true in Git?

If you would like to remove all the files and modifications that differ from your origin branch but would like to keep all the ignored files (ex. node_modules, .vscode, .idea etc..) the best choice is to combine these two commands:

 git reset --hard && git clean -f

This will reset all modified files and will clean all the unstaged ones.
