How to view file diff in git before commit

git git-diff

If you want to see what you haven't git added yet:

git diff myfile.txt

or if you want to see already added changes

git diff --cached myfile.txt

git git-diff

git diff HEAD file

will show you changes you added to your worktree from the last commit. All the changes (staged or not staged) will be shown.

git git-diff

To check for local differences:

git diff myfile.txt

or you can use a diff tool (in case you'd like to revert some changes):

git difftool myfile.txt

^{To use git difftool more efficiently, install and use your favourite GUI tool such as Meld, DiffMerge or OpenDiff.}

Note: You can also use . (instead of filename) to see current dir changes.

In order to check changes per each line, use: git blame which will display which line was commited in which commit.

To view the actual file before the commit (where master is your branch), run:

git show master:path/my_file
