| 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 | |
