Remove ignored files from your repository's directory

While a regular git clean will ignore them as well, passing the -x switch changes that:

• Dry run: git clean -xn
• Clean files: git clean -x
• Clean by passing the -f (force) or -d (directories): git clean -xdf

• Changes on dev branch but not on master: git diff master..dev
• Changes on dev branch that affect a specific file: git diff master..dev -- file/path/lib.py

Get the current revision hash for scripting

• Latest revision on the currently active branch: git rev-parse HEAD

List changed files in a commit
