| NAME |
| ---- |
| git-patch-id - Compute unique ID for a patch |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'git patch-id' < <patch> |
| |
| DESCRIPTION |
| ----------- |
| A "patch ID" is nothing but a SHA-1 of the diff associated with a patch, with |
| whitespace and line numbers ignored. As such, it's "reasonably stable", but at |
| the same time also reasonably unique, i.e., two patches that have the same "patch |
| ID" are almost guaranteed to be the same thing. |
| |
| IOW, you can use this thing to look for likely duplicate commits. |
| |
| When dealing with 'git diff-tree' output, it takes advantage of |
| the fact that the patch is prefixed with the object name of the |
| commit, and outputs two 40-byte hexadecimal strings. The first |
| string is the patch ID, and the second string is the commit ID. |
| This can be used to make a mapping from patch ID to commit ID. |
| |
| OPTIONS |
| ------- |
| <patch>:: |
| The diff to create the ID of. |
