You can make git diff and git log ignore new and deleted files by using the --diff-filter option with the git diff and git log commands. The --diff-filter option allows you to specify which types of file changes to include or exclude from the output.

To ignore new and deleted files, you can use the --diff-filter option with the ACMRT parameters. Here are the commands:

To make git diff ignore new and deleted files:

git diff --diff-filter=ACMRT

To make git log ignore new and deleted files:

git log --diff-filter=ACMRT

The A parameter in --diff-filter specifies that you only want to show added files, C specifies that you only want to show copied files, M specifies that you only want to show modified files, R specifies that you only want to show renamed files, and T specifies that you only want to show files that have had their type changed.

By specifying these parameters, you can make git diff and git log ignore new and deleted files and only show changes to existing files.

In the other hand shortest example to make git-diff and git log ignore new and deleted files?

The --diff-filter option works with both diff and log.

I use --diff-filter=M a lot which restricts diff outputs to only content modifications.

To detect renames and copies and use these in the diff output, you can use -M and -C respectively, together with the R and C options to --diff-filter.
