How can I discard modified files?

Question

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.

Answer 1

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.

Answer 2

To restore:

modified: specific_filename

git checkout <specific_filename>

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

Answer 3

You can remove untracked files with clean as well

git clean -f

Answer 4

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"?

Answer 5

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; }

Answer 6

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
