# but do track lib.a, even though you're ignoring .a files above
!lib.a

# only ignore the TODO file in the current directory, not subdir/TODO
/TODO

# ignore all files in any directory named build
build/

# ignore doc/notes.txt, but not doc/server/arch.txt
doc/*.txt

# ignore all .pdf files in the doc/ directory and any of its subdirectories
doc/**/*.pdf

Branches

To get remote branches localy:

git branch -r | grep -v '\->' | sed "s,\x1B\[[0-9;]*[a-zA-Z],,g" | while read remote; do git checkout "${remote#origin/}"; done

or just:

git branch -r | grep -v '\->' | while read remote; do git checkout "${remote#origin/}"; done

To keep password for remote in memory for a few minutes:
git config --global credential.helper cache

graph LR;
  untracked -- "git add" --> staged;
  staged    -- "???"     --> tracked/comitted;

%% example arrow without text: 
  A --> B;
