How to show uncommitted changes in Git and some Git diffs in detail

Question

How do I show uncommitted changes in Git?

I STFW'ed, and these commands are not working:

teyan@TEYAN-THINK MINGW64 /d/nano/repos/PSTools/psservice (teyan/psservice) $ git status On branch teyan/psservice Your branch is up-to-date with 'origin/teyan/psservice'. Changes to be committed:   (use "git reset HEAD <file>..." to unstage)          modified:   psservice.c         modified:   psservice.vcxproj.filters   teyan@TEYAN-THINK MINGW64 /d/nano/repos/PSTools/psservice (teyan/psservice) $ git diff  teyan@TEYAN-THINK MINGW64 /d/nano/repos/PSTools/psservice (teyan/psservice) $ git diff master fatal: ambiguous argument 'master': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]'

How to show uncommitted changes in Git

The command you are looking for is git diff.

git diff - Show changes between commits, commit and working tree, etc

---

Here are some of the options it expose which you can use

git diff (no parameters)
Print out differences between your working directory and the index.

git diff --cached:
Print out differences between the index and HEAD (current commit).

git diff HEAD:
Print out differences between your working directory and the HEAD.

git diff --name-only
Show only names of changed files.

git diff --name-status
Show only names and status of changed files.

git diff --color-words
Word by word diff instead of line by line.

Here is a sample of the output for git diff --color-words:
