Motivation
To be able to see a file in your git repository at a certain revision. This can easily be done with
git show <rev> <file>, but I want it to have in my editor of choice with syntax highlighting turned on (which is why the temporary file is needed, to preserve the extension)Usage
Put this into your
~/.bashrc, then you cann use it withgshow <revision> <file>, e.g.gshow 3f51bc4d74ec1ca054a7197be16e6fe095c78b88 export.py.
