View the change history of a file using Git versioning
You can use
git log -p filenameto let Git generate the patches for each log entry.
See
git help logfor more options - it can actually do a lot of nice things :) To get just the diff for a specific commit you can
git show HEADor any other revision by identifier. Or use
gitkto browse the changes visually.
git log --follow -p -- path-to-file
This will show the entire history of the file (including history beyond renames and with diffs for each change).
In other words, if the file named bar was once named foo, then git log -p bar (without the --follow option) will only show the file's history up to the point where it was renamed -- it won't show the file's history when it was known as foo. Using git log --follow -p bar will show the file's entire history, including any changes to the file when it was known as foo. The -p option ensures that diffs are included for each change.
