View the change history of a file using Git versioning

Question

How can I view the change history of an individual file in Git, complete details with what has changed?

I have got as far as:

git log -- [filename]
         


        

Answer 1

Summary of other answers after reading through them and playing a bit:

The usual command line command would be

git log --follow --all -p dir/file.c

But you can also use either gitk (gui) or tig (text-ui) to give much more human-readable ways of looking at it.

gitk --follow --all -p dir/file.c

tig --follow --all -p dir/file.c

Under debian/ubuntu, the install command for these lovely tools is as expected :

sudo apt-get install gitk tig

And I'm currently using:

alias gdf='gitk --follow --all -p'

so that I can just type gdf dir to get a focussed history of everything in subdirectory dir.
