### Showing only files that changed in the last commit

You can always see the changes made in the last commit using

git show


But, on occasions, you just want to see the list of files changed. You can do this by simply passing the --stat flag:

git show --stat


### Making git ignore changes in file permissions

Sometimes you’d git to not recognize the changes in the file permissions. This can happen very frequently if you’re mounting file systems across the network or a virtual machine. For a particular repository, you can locally set the fileMode to false like this:

git config --local core.fileMode false


or, simply

git config core.fileMode false


The commands above will change the ./git/config file to add/edit the following line

[core]
fileMode = false


As always, you can use --global flag instead of --local flag to make a system wide change. The global change will add/edit ~/.gitconfig file.

### Making git ignore changes in line endings

Line ending in Windows is \r\n, which is the combination of Carriage Return (CR) of \r and the Line Feed (LF) \n. Line ending in Unix is only \n. See the Wikipedia entry on Newline for a better understanding.

When you edit a file on Windows or on a text editor that changes line endings, you will notice that git diff shows that the entire file has changed. You might see ^M at the end of lines when you see the output of git diff.

When git diff shows that the entire file had changed, you cannot see the meaningful changes you’ve made. To make git ignore the line endings, you can use the --ignore-space-at-eol flag:

git diff --ignore-space-at-eol


This will still show the changes that don’t involve the line endings.
